Measurement of the activity of hydrogen ions (pH, pH25) of "ultrapure" waters (including water with a reduced electrical conductivity of 0.055 microns /cm) and alkaline waters containing ammonia or amines. Measurement of electrical conductivity (UEP, UEP25), temperature of aqueous media. Control of water-chemical regimes at energy facilities. A new patented measurement method that does not require calibration. The absence of elements that degrade in "ultrapure" water. Convenience and accuracy of measurement | Automatic thermal compensation. Freely programmable measurement ranges. Measurement of conductivity in the range up to 30 microns/cm. Communication with external devices | Galvanically isolated current outputs 0-5/4-20/0-20 Ma. RS 485 port. MODBUS RTU exchange protocol. Relay of "dry" contacts (6 pcs.) with programmable functions. Durable aluminum housing IP65 | The device is reliably protected from dust and moisture. A single protective box that combines the secondary converter and the hydraulic part. Intelligent data processing algorithms. 5.7" graphic touchscreen display, 65535 colors, resolution 640*480 pixels.

It is designed to measure pH, ion concentration and redox potential (Eh) with simultaneous temperature measurement. It allows the determination of nitrates in accordance with GOST 34570-2019.
