Chematest 42
The Chematest 42 includes an individual factory calibration and every device guarantees a robust and accurate low-rage turbidity measurement from 0.01 FNU/NTU. The high precision and repeatability results from the fixed cuvette position – the cuvette is mechanically aligned to the very same position throughout all measurements which also allows a smart cuvette offset management.
Furthermore, the turbidity measurements are fully compliant to DIN ISO 7027-1 and USEPA 180.1. All photometric and nephelometric measurement results can be validated at any time with stable, fully traceable standards through the VeriKit accessory.
