Inline HST/HRA corrosion inhibitor tracer sensor (0-7.5ppm). 4-20mA + RS-485, 7-pin.

The Pyxis ST-565 is an inline sensor that measures tolyltriazole (TTA) / HST-HRA corrosion inhibitor levels, supporting closed-loop and cooling water treatment programmes. It reports concentration across a 0-7.5ppm range and communicates via 4-20mA analog output and RS-485 Modbus through a 7-pin connector.
The Pyxis ST-565 is an inline tracer sensor that measures tolyltriazole (TTA) / HST-HRA corrosion inhibitor levels, supporting closed-loop and cooling water treatment programmes. Continuous inline measurement gives operators real-time visibility into corrosion inhibitor dosing, helping confirm that protective chemistries are being maintained at the intended concentration.
It reports concentration across a 0-7.5ppm range and communicates via a 4-20mA analog output and RS-485 Modbus digital signal, both wired through a 7-pin connector for integration with plant control and monitoring equipment.
This sensor is designed for treatment providers and facility operators managing closed-loop or cooling water systems that rely on TTA/HST-HRA corrosion inhibitor chemistries.
Measures tolyltriazole (TTA) / HST-HRA corrosion inhibitor levels in real time across a 0-7.5ppm range, giving operators direct visibility into treatment chemical performance.
Dual 4-20mA analog and RS-485 Modbus outputs through a 7-pin connector let the sensor feed data straight into existing SCADA or controller setups.
It measures tolyltriazole (TTA) / HST-HRA corrosion inhibitor concentration, used in closed-loop and cooling water treatment programmes.
It covers a 0-7.5ppm range.
It is an inline sensor that mounts directly into the process water line for continuous monitoring.
It provides 4-20mA analog output and RS-485 Modbus communication through a 7-pin connector.
