Pyxis ST-725 Inline Stainless Steel Ultra-Low Conductivity + Temperature Analyser (Lower Range)

Model:
ST-725
Brand:
Pyxis

The Pyxis ST-725 is a stainless steel inline conductivity and temperature analyser built for ultra-low conductivity measurement, covering a narrower 0.02-200uS/cm range for finer resolution in very pure water. It reports conductivity and temperature from a single sensor, with dual 4-20mA analog outputs plus RS-485 Modbus via an 8-pin connector.

Ultra-low range sensitivity — measures conductivity down to 0.02uS/cm, with a narrower top end for finer resolution in very pure water
Two measurements, one sensor — reports conductivity and temperature from a single inline unit
Ultra-low range sensitivity — measures conductivity down to 0.02uS/cm, with a narrower top end for finer resolution in very pure water

Description

The Pyxis ST-725 is a stainless steel inline conductivity and temperature analyser built for ultra-low conductivity measurement, with a narrower 0.02-200uS/cm range that provides finer resolution than the standard ultra-low variant. This makes it well suited to applications requiring precise tracking of very pure water.

It reports conductivity and temperature from a single sensor, in a stainless steel body designed for durability in industrial settings.

Dual 4-20mA analog outputs plus RS-485 Modbus via an 8-pin connector support direct integration into process control systems.

Why Use This

High-Purity Water Monitoring

The ultra-low range (0.02-200uS/cm) offers finer resolution for monitoring very high-purity process water.

Durable Construction

Stainless steel body suits demanding industrial installations.

Flexible System Integration

Dual 4-20mA outputs and RS-485 Modbus support integration with control and monitoring systems.

Applications

  • Very high-purity water monitoring — finer resolution tracking for demineralized or ultrapure streams
  • RO permeate quality verification — monitoring low conductivity in reverse osmosis product water
  • Precision process water control — where narrower-range resolution is needed over the standard ultra-low sensor

FAQ

How is the ST-725 different from the ST-724?

The ST-725 covers a narrower 0.02-200uS/cm range, which provides finer resolution for very high-purity water compared to the wider 0.02-1,000uS/cm range of the ST-724.

Does it report temperature alongside conductivity?

Yes, both are measured from a single inline sensor.

What outputs does it support?

Dual 4-20mA analog outputs plus RS-485 Modbus, via an 8-pin connector.
