Thickness standards are used to verify the accuracy and operation of coating thickness gauges. As a component of ISO 9000 or in-house quality control procedures, they are a practical alternative to sending instruments to DeFelsko for calibration.
DeFelsko offers various solutions for this process and this group of products is their group of metal zero plates, as follows:
- Aluminum. Available in small and medium sizes.
- Steel. Available in small, medium and large sizes.
-
Each DeFelsko instrument family is factory calibrated and is designed to be ready-to-use upon arrival. Best practice and specifications determine when instruments should have their calibrations rechecked. For the PosiTector UTG probes, DeFelsko offers five different variations of stainless steel Step Blocks that are factory certified for checking their calibration, as follows:
- B1. Standard range Imperial. Five steps (100, 200, 300, 400, and 500 mils).
- B1M. Standard range Metric. Five Steps (2.5, 5, 7.5, 10, and 12.5 mm).
- B2. High range Imperial. Eight steps (1", 1.5", 2", 2.5", 3", 3.5", 4", and 4.5").
- B2M. High range Metric. Eight steps (25, 37.5, 50, 62.5, 75, 87.5, 100, and 112.5 mm).
- P. (Use with PosiTector UTG P probe.) Imperial labeled at 40, 60, 80, and 100 mils. (Metric equivalent 1, 1.5, 2, and 2.5 mm)

Surface Profile Standards and Shim Sets are used for checking and adjusting calibration on PosiTector SPG, PosiTector RTR (and other depth micrometer probe) instruments. Product details as follows:
- For the PosiTector SPG:
- Certified Standards. Typically used in calibration labs, these are available for any user who desires this level of verification. Includes serialized and traceable height standards mounted to a metal plate. Labeled in both metric and imperial units.
- Certified Shim Set. Premium option for everyday use with any depth micrometer using a fine-pointed probe (as well as the PosiTector SPG). Includes 3 shims at 50/125/500 microns (2, 5, 20 mils).
- Zero Glass Plate / Metal Shim (Non-Certified). For training and quick checks for accuracy, each new SPG unit comes with this verification set, with replacement / additional units also available for purchase here.
- For the PosiTector RTR: (both models unless otherwise noted)
- Certified Shim Set. Premium option to check Peak Height measurements for accuracy verification on the RTR series (as well as other spring micrometer replica tape readers).
- Non-Certified Shim Set (aka Precision Plastic Shim Set). Lower cost version of the above, ideal for everyday accuracy verification.
- Single Check Shim. This non-certified shim comes standard with each new RTR and is available as a replacement if desired, although it is more economical to purchase the above full set.
- Check Tape. This reusable tape is used to verify Peak Density, and is used on the RTR 3D model only.
- For the PosiTector SPG:

A top priority for corrosion control contractors is knowing how to dry air for sandblasting. It is essential that you remove the moisture from your compressed air for efficient blasting. Moisture can cause your abrasive to clog, slow down your blasting speed and even cause your freshly blasted surface to rust.
Cool, dry air exits the air dryer and is connected to the hose for your blast machine. The result keeps moisture from the blasting surface which minimizes any potential rusting before the protective coating is applied.
Air dryers are used to dry the air between the compressor and the blasting or spraying equipment. Warm, moist air from the compressor enters the air prep dryer and travels into a radiator where the air is cooled. As the temperature drops from warm to cool, it then enters the expansion tank which causes the water to drop to the bottom. Cool, dry air exits the air dryer and is connected to the hose for your blast machine. The result keeps moisture from the blasting surface which minimizes any potential rusting before the protective coating is applied.
