Pyxis ST-820 Online Full-Spectrum Multi-Parameter Probe

Model:
ST-820
Brand:
Pyxis Lab

The Pyxis ST-820 is an online full-spectrum probe that simultaneously measures multiple water quality parameters, including Nitrate, COD, BOD, and TOC, from a single sensor with customisable ranges per parameter. It connects via an 8-core 10m open cable and outputs data through both RS-485 and 4-20mA for continuous process monitoring.

Description

The Pyxis ST-820 is an online full-spectrum multi-parameter probe that simultaneously measures multiple water quality indicators, including Nitrate, COD, BOD, TOC, and others, from a single sensor. Each parameter’s measurement range can be customised to the application, allowing the probe to be configured for the specific water quality profile being monitored.

The ST-820 connects via an 8-core 10m open cable and outputs data through both RS-485 and 4-20mA, supporting integration with plant monitoring and control systems.

By consolidating several water quality parameters into one probe, it reduces the number of separate instruments needed for continuous multi-parameter process monitoring.

Why Use This

Simplified Multi-Parameter Monitoring

Measures Nitrate, COD, BOD, TOC, and other parameters simultaneously from a single probe, reducing the number of sensors needed.

Configurable to Your Process

Each parameter’s range can be customised to match specific application requirements.

Applications

  • Continuous multi-parameter water quality monitoring — Nitrate, COD, BOD, TOC, and other parameters from one probe
  • Process monitoring requiring customised parameter ranges — configurable per-parameter measurement ranges

FAQ

Which parameters can the ST-820 measure?

It simultaneously measures Nitrate, COD, BOD, TOC, and other parameters from a single probe.

Can the measurement ranges be adjusted for my application?

Yes, each parameter’s measurement range is customisable to the application.

How does the probe connect to a control system?

It uses an 8-core 10m open cable and outputs data via both RS-485 and 4-20mA.
