Concentration Measurement Device
Handheld Refractometers are used in DPI to measure the refraction of light in a diluted solution. From that the concentration of penetrants can be determined when that value is compared to the refraction of light through just water. This unit is easy to read and comes in a heavy duty case as standard.
- Can be supplied with full certification upon request.
- Replacement Refractometer flaps available - 5 Pack.
