The Starr Instruments TE-242 Grindometer, is specifically designed for assessing the fineness of grind in coating materials. This precision instrument, modeled after the Grindometer acc to Hegman, Model 232, is an indispensable tool in the quality control process for coatings.

The TE-242 Grindometer features a block of hardened steel, treated to ensure dimensional stability and longevity. The instrument has two precisely defined wedge-shaped channels meticulously cut into the block. The design facilitates the creation of a liquid wedge-shaped specimen of the test substance, making it convenient for users to visually inspect and determine the grain size. During the assessment, it becomes readily apparent through visual inspection if the grain size exceeds the local dimensions of the wedge channel. The critical information is derived from the channel depth, where the boundary between the smooth and uneven surface areas defines the fineness of the grind. The instrument's ability to produce accurate and reliable readings is paramount in gauging the quality and performance of coating materials.

Measuring the depth of each channel is made seamless with the TE-242 Grindometer, thanks to the microscale engraved on one of the longitudinal sides of the block. The gauge measures in two different scales through seperate channels, calibrated in both micrometers (μm), and the corresponding Hegman scale (HS).
