The PH850-SA from Apera Instruments is a handy and easy-to-use meter for the determination of pH, ORP (electrode available separately e.g. 301Pt-C) and temperature. It is ideal for carrying out precise and reliable measurements of solutions with a strongly alkaline/alkaline character (up to 14 pH). The LabSen® 843 combined pH/temp. electrode included in the scope of delivery is equipped with a special HA glass membrane, which ensures that the alkali error is minimized when measuring high pH values. The electrode can be used at temperatures up to 130°C (266°F) and is therefore also suitable for high-temperature solutions. The PH850-SA 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® 843 combined pH/temp. electrode for strongly alkaline solutions and high-temperature solutions
  • 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

The meter is RoHS and EC certified and has a 3 year warranty (6 months on the electrode).

Electrode

The LabSen® 843 pH electrode from Apera Instruments is manufactured using proprietary Swiss sensor technology and materials. It was specially developed for measuring strongly basic solutions (10-14 pH) and has an integrated temperature sensor, which enables automatic temperature compensation for pH measurements.

This electrode has the following features:

    • Proprietary pH sensor technology and materials from Switzerland
    • Especially for pH measurement of strongly basic solutions (10-14 pH) with minimized alkali error
    • Silver ion trap reference system prevents contamination of the electrode
    • Glass membrane up to 10 times more robust than conventional products
    • Blue gel electrolyte, does not flow and does not cause air bubbles
    • Integrated temperature sensor enables automatic temperature compensation
