Chematest 42

Swan Analytical Instruments Chematest 42

The unique multiparameter device which includes turbidity measurements

Turbidity measurements are fully compliant to DIN ISO 7027-1 and USEPA 180.1. The individual factory calibration of every device guarantees a robust and accurate low-rage turbidity measurement from 0.01 FNU/NTU.

The instrument offers high precision and repeatability of results due to the fixed cuvette position – the cuvette is mechanically aligned to the very same position throughout all measurements which allows a smart cuvette offset management.

All photometric and nephelometric measurement results can be validated at any time with stable, fully traceable standards through the VeriKit accessory

Public Pools

All relevant parameters in one device. Using the proven DPD-method ensures precision and reproducibility of online analytics. Saves maintenance time and costs for pool control and water treatment.

Potable Water

Verify your online measurements for additional security. Handy to use and suitable for even the most remote sampling points where no online monitor can be installed. Suitable from the source to the distribution network.

Pharmaceutical & Life Sciences

Quick and easy QA/QC spot-check analysis to monitor the effective sanitisation of your pharmaceutical water for compliance. Provides confidence in analysis accuracy by using traceable standards for verification of the measurement precision.

Food & Beverage

Operators of industrial plants require verification tools for their online water analytics to maintain the process water. Also, aquarium or fish farming operators require a good water quality monitoring to reduce maintenance costs.
