QR Code Reading reduces human error by eliminating the need for users to manually enter this information into the device while on the busy manufacturing floor.


User Management

This feature allows management to add individual user profiles and if necessary, limit capabilities to eliminate unwanted changes to device settings. Each inspection record automatically logs the username conducting the inspection for easy tracking and auditing purposes.



The Surface Analyst 5001 provides real-time output of inspection data into Manufacturing Execution Systems via RS232 output or ethernet API.


Enhanced Ballistic Deposition

Ballistic Deposition is BTG Labs' patented approach to depositing a drop of fluid to measure real-world surfaces that may have different roughnesses, chemical variation and complex geometries (vertical, upside down, small).

After the drop is deposited, this innovative method uses a top-down view to take a precise image of the drop in order to measure the contact angle. 


GEM Drop

GEM Drop is the dispense system that meticulously builds the perfect fluid drop on material surfaces for the most reliable and accurate contact angle measurement.

GEM Drop takes sensitive surface chemistry measurements out of the laboratory and puts them directly on the production line. This approach allows for precise inspections in crevices and tiny drops on very complex materials.



Lucent is a unique lighting configuration that controls the illumination of the surface being inspected.  

By providing the ideal lighting environment, the Surface Analyst 5001 captures high-quality images and can easily manage challenging surfaces with varying finishes and reflectivity. 


Surface Profiles

Using the Surface Profiles feature, Admins can create unique profiles with customized inspection parameters to increase accuracy when measuring dissimilar materials.

Surface Profiles ensure precise measurements on materials with varying finishes, textures, conditions, or surface preparations.


Dynamic Detection

This innovative approach to powerful image analysis provides the most precise top-down measurement of contact angle. 

Dynamic Detection enables the device to provide a contact angle that more accurately represents the droplet's interaction with the surface, therefore it is capable of exceeding the accuracy of laboratory-type goniometer contact angle measurements.

Dynamic Detection's combination of image analysis tool-sets are so intelligent, it provides perfect contact angle results in imperfect situations.


Wetting Analytics

The Wetting Analytics feature analyzes dynamic drop wet-out and alerts user to the presence of a water-soluble chemical on the material. This information is vitally important for processes that include cleaning and washing steps where improper rinsing can leave surfactants, detergents, or other hydrophilic agents on the surface.

For some applications, water-soluble agents are a necessary component of a coating, and for others it is a detrimental contaminant in an adhesion, coating, or sealing process.

BTG Labs' Wetting Analytics software will quantify the amount and uniformity of these substances to ensure downstream product performance.


Pass/Fail Mode

Enabling this mode allows management to input customizable pass/fail tolerances that read out to the operator simply, as Pass or Fail. This provides the results in a simple way without the operator having to understand the meaning of the inspection number.


Near Failure Notification 

Sometimes, although surfaces are still "passing" the inspection phase, the process is actually approaching failure. This feature is designed to warn users if their process is slowly drifting toward the fail-limit. When a test is near the set failure tolerance, the Pass/Fail message turns yellow.


Dyne Mode

This optional software package displays results in dyne/cm. This mode allows manufacturers to ease the transition away from harmful dyne solutions. Dyne Mode allows users to continue measuring to an existing dyne specification but without the use of destructive ink. This mode provides dyne results without the subjective test interpretations.


Custom Inspection Attachments

Whether you are inspecting a heavily dimpled golf ball, a fully-populated PCB board, a convex lens or a metal gasket with narrow channels, BTG Labs' custom inspection attachments make the job as easy as though it were a flat surface.

BTG Labs designs custom attachments, giving users complete control over where the measurement is taken on the surface to ensure consistency and accuracy.


Quality Check Station

Partner with BTG Labs to design a custom Surface Check Station that will keep either the handheld Surface Analyst 5001 stationary, or the material surface in place.

BTG Labs' Surface Check Stations remove any variability in inspection placement and ensure precise measurements across complex-shaped products.

Check Stations feature the ability to communicate and connect to MES through RS232 and ethernet API.


Wearable Sling

The new, wearable Surface Analyst Sling provides a convenient, hands-free method for holstering the device to the body, providing greater agility and freedom of movement on the manufacturing floor.


Extended Tether

Users have the option for an extended tether--up to 6 meters--for an easier reach into more challenging spaces.

The Extended Tether can be combined with the use of a Quality Check Station to fix the Surface Analyst 5001 device in place, allowing for precise and repeatable inspection of large material surfaces without the need to move the device.

Surface Analyst 5001 FAQ

How does the Surface Analyst determine surface quality?

Surface Quality means different things to different people. For those interested in surface characteristics that depend on surface chemical composition and uniformity (such as cleanliness, coating adhesion, and adhesive bond performance), the contact angle-based measurement performed by the Surface Analyst 5001 provides unequalled sensitivity to minute changes in these properties.

With our patented Ballistic Deposition technology, the Surface Analyst 5001 is sensitive to the contact angle hysteresis of a surface. This makes the Surface Analyst 5001 significantly more sensitive to most surface chemical properties than traditional goniometers.

What makes the Surface Analyst different than a side-view goniometer?

One of the most important features of the Surface Analyst 5001 is its innovative use of top-down imaging of the deposited drop, rather than the side view used by laboratory-type goniometers.

BTG Labs' top-down approach allows contact angle measurements to be obtained on surfaces of real-world objects that have features or orientations that prevent side viewing of a drop. Examples of these types of surfaces include: a populated circuit board, a tiny catheter, a machined metal casting, or a rough composite material surface where the hills and valleys prevent seeing the drop's edge with a side view.

When a drop of fluid is deposited on a real-world surface, it rarely produces a perfectly round droplet due to texture or chemical heterogeneity of the surface. This means there will be a range of contact angles around the drop perimeter. A side-view measurement only measures 2 of those angles and can give an erroneous picture of the true surface state.

The Surface Analyst 5001 with Dynamic Detection uses a patented top-down imaging approach to measure up to 200 points around the entire drop.

This innovative measurement provides a contact angle that more accurately represents the droplet's interaction with the surface and provides precise information about the true state of the surface.

Can the Surface Analyst measure on different types of surfaces?

The Surface Analyst 5001 has been used successfully on a wide variety of surfaces including: polymer films, metal castings, medical catheters, semiconductors, composite material, populated circuit boards, structural glass and much more. For applications where surface chemical properties are important, the Surface Analyst 5001 can provide rapid, quantitative feedback regarding the surface's quality, treatment level, cleanliness, and consistency.

Does surface roughness affect contact angle measurement accuracy?

Interrogation of rough surfaces is another situation where the Surface Analyst 5001 excels over all other contact-angle based measurements. Unlike side view goniometers where surface roughness obscures the view of the drop edge, the top-down contact angle measurement of the Surface Analyst 5001 images the entire drop perimeter regardless of roughness and returns the true average contact angle of the entire drop perimeter. The resulting number reflects the true surface state.

How accurate is the Surface Analyst at measuring contact angle?

The Surface Analyst 5001 is calibrated to match a NIST-traceable laboratory goniometer. It repeatedly proves to have higher precision (i.e. more repeatable) than sideview goniometers on real-world surfaces.

On chemically uniform surfaces, contact angle measurements using the Surface Analyst 5001 show standard deviations of less than one degree.
