PH850-MS Portable pH Meter for Test Tubes and Small Sample Volumes

The picture may be different from the article and can include supply, which is not in the standard scope.

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.

  • Equipped with the LabSen® 243-6 pH/temp. electrode for small sample volumes
  • Silicone case provides safe & firm grip and protects from shocks
  • Waterproof and dustproof (IP57) for use in harsh environments
  • Fold-out stand for convenient indoor operation
  • Quick and easy 1- to 3-point calibration
  • Large, illuminated LCD simultaneously displays conductivity value and temperature, as well as additional measurement and calibration information
  • Self-diagnosis supports calibration or troubleshooting
