The PH850-HT from Apera Instruments is a robust and easy-to-use pH meter designed for precise pH, ORP (electrode sold separately, e.g., 301Pt-C), and temperature measurements in high-temperature (up to 130°C) and caustic solutions. It is particularly suitable for industrial, laboratory, and field applications that involve high-temperature or caustic environments.

The included LabSen® 861 pH electrode features a special PSY glass membrane, which is highly resistant to chemical corrosion. This makes the electrode ideal for complex and caustic solutions, maximizing the electrode's reliability and service life. The set includes an MP500 temperature sensor for temperature measurement, ensuring accurate and stable results even in challenging conditions.

The PH850-HT is protected by a durable silicone cover, making it waterproof and dustproof (IP57), perfect for field use in harsh environments. The fold-out stand adds convenience for indoor use, and the large illuminated LCD displays pH, temperature, and additional measurement data. The meter supports quick 1- to 3-point calibration and features a self-diagnosis function for troubleshooting.
