The Apera PH700-HT (AI5019) is a laboratory-grade benchtop pH meter specifically designed for measuring high-temperature liquids up to 130°C and chemically aggressive or caustic water solutions. It uses the Swiss-engineered LabSen® 865 pH/temperature electrode, featuring a chemically resistant PHY glass membrane, a PTFE anti-clog junction, and a Silver Ion Trap reference system. These features help maintain reliable measurements in demanding chemical environments where conventional pH electrodes may deteriorate or become unreliable. Built on Apera's PH700 platform, the instrument provides ±0.01 pH accuracy, automatic temperature compensation, electrode-condition diagnostics, and internal storage for 50 measurement sets. It is suitable for laboratories and commercial cultivation facilities that need to measure heated nutrient solutions, concentrated stock solutions, and chemical process liquids.

Key Advantage: The Apera PH700-HT combines laboratory-grade pH measurement with an electrode specifically engineered for high-temperature and caustic environments. Its 130°C sample-temperature rating, chemically resistant PHY glass membrane, and PTFE anti-clog junction make it suitable for demanding applications beyond the operating limits of many standard pH probes. Automatic calibration diagnostics and 50-set data storage further support quality control in commercial laboratories and cultivation facilities.
