The PH850-MS from Apera Instruments is a handy and easy-to-use meter for the determination of pH, ORP (electrode sold separately e.g. 301Pt-C) and temperature. It is particularly suitable for pH measurement of small test quantities or in thin sample containers.

Due to its slim design, the LabSen® 243-6 pH electrode included in the scope of delivery can measure sample volumes of up to 200µl, and even up to 60µl with a suitable test tube. It operates at temperatures up to 100°C and has an integrated temperature sensor, which enables automatic temperature compensation (ATC). The PH850-MS is protected by a silicone cover and is waterproof and dustproof (IP57), making it particularly well suited for field use, even in harsh environments.
