The PH850-PW from Apera Instruments is a compact, easy-to-use pH meter designed specifically for measuring pH, ORP (electrode sold separately, e.g., 301Pt-C), and temperature in low ion concentration solutions such as pure, distilled, or deionized water.

Equipped with the LabSen® 803 pH electrode, the PH850-PW provides fast, accurate, and reproducible pH measurements. The electrode features a unique L-type glass membrane and a movable sleeve, allowing you to adjust the infiltration rate of the electrolyte for better measurement performance. The integrated temperature sensor supports automatic temperature compensation (ATC) for accurate results across varying temperatures.

The PH850-PW is housed in a durable silicone cover that provides a secure grip and protects against shocks. Its IP57 waterproof and dustproof rating ensures reliability even in harsh field conditions. The large illuminated LCD displays pH and temperature readings, as well as additional calibration information, making it easy to monitor results. The meter also supports quick 1- to 3-point calibration and features self-diagnosis for troubleshooting.
