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.

Electrode

The LabSen® 243-6 from Apera Instruments is a pH electrode with integrated temperature sensor and is manufactured using patented Swiss sensor technology and materials. It is particularly suitable for measuring small-volume samples (≥0.2 ml) and for use in thin test tubes.

Long-life reference system – The LabSen 243-6 pH electrode uses a long-life reference system consisting of a glass tube, AgCl and a reference silver wire. The top of the thin glass tube is filled with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference electrode and extends the life of the electrode.

LabSen S-type semi-micro glass membrane – With a length of 100mm, a diameter of 6mm and low membrane resistance (<350MΩ), the electrode enables reliable measurements of sample volumes ≥0.2 ml at temperatures up to 100°C.
