Description
The ST-725 is an industrial-grade, inline ultra-low conductivity sensor designed for pure & ultra-pure water applications. It can be used for ultra-low conductivity measurement of pure water, ultra-pure water and deionized water including:
- Boiler Feedwater and Condensate
- RO and EDI/EDR Process Water
- Ion Exchange
- Distillation
- Semi-Conductor Cleaning
- Degas Conductivity and Other Process Applications
So, these are ‘smart sensors’ with a built-in transmitter supporting digital & analog signal outputs, and are designed to simplify field installation, calibration and operation. The sensors offer simple 3/4” MNPT threaded installation and are constructed with a Hastelloy electrode tip & stainless-steel body. The ST-725 sensor can be wirelessly calibrated with uPyxis® app when used with the MA-CR Bluetooth® adapter. The sensors both offer (2) 4–20mA Analog outputs, one for conductivity and one for temperature, as well as RS-485 Modbus output for a broad array of installations that desire to connect the smart sensor directly to any receiving controller, PLC or DCS network. The ST-725 has a built in RTD for the automatic compensation of sample temperature.
