The PH850-MS from Apera Instruments is a portable and easy-to-use pH meter designed for precise pH, ORP (electrode sold separately, e.g., 301Pt-C), and temperature measurements, especially in small sample volumes. Its slim design makes it ideal for measuring small test quantities or in thin sample containers.

The included LabSen® 243-6 pH electrode is specially designed for measurements in samples as small as 200µl, and even as low as 60µl with a suitable test tube. The electrode can operate at temperatures up to 100°C and features an integrated temperature sensor that provides automatic temperature compensation (ATC) for accurate results in varying conditions.

The PH850-MS is protected by a durable silicone cover, making it waterproof and dustproof (IP57), which is perfect for field use in tough environments. The fold-out stand makes it convenient for indoor use, and the large illuminated LCD displays pH, temperature, and additional calibration information. The meter supports easy 1- to 3-point calibration, and the self-diagnosis feature helps with troubleshooting.
