The PH850-WW from Apera Instruments is a compact, easy-to-use pH meter designed for precise measurement of pH, ORP (electrode sold separately, e.g., 301Pt-C), and temperature in challenging environments. Specifically suited for wastewater, emulsions, dirty water, and turbid solutions containing sulfides and proteins, the PH850-WW ensures reliable readings even in difficult conditions.

The included LabSen® 333 pH electrode is equipped with a solid electrolyte and a hole diaphragm structure, preventing clogging and ensuring consistent performance. The polyoxymethylene (POM) sheath protects the electrode from corrosion and impact damage, making it highly durable for field use. The integrated temperature sensor allows for automatic temperature compensation (ATC), providing accurate results across a wide range of temperatures.

The PH850-WW features a rugged silicone cover, making it IP57 waterproof and dustproof, ideal for field use in harsh environments. The fold-out stand provides added convenience for indoor operation, while the large illuminated LCD displays pH and temperature readings, as well as additional measurement and calibration data. The meter supports quick 1- to 3-point calibration and includes a self-diagnosis feature for troubleshooting.
