Online full-spectrum nitrate probe, mid range (0-50mg/L). RS-485 + 4-20mA, 8-core 10m open cable.

The Pyxis ST-801 is a mid-range online full-spectrum nitrate probe for continuous water quality monitoring, measuring nitrate concentrations from 0-50mg/L. It connects via an 8-core 10m open cable and outputs data through both RS-485 and 4-20mA for integration with plant monitoring and control systems.
The Pyxis ST-801 is a mid-range online full-spectrum nitrate probe for continuous water quality monitoring, measuring nitrate concentrations across a 0-50mg/L range. It uses full-spectrum optical measurement technology to provide real-time nitrate data without the reagents required by traditional colorimetric methods.
The probe connects via an 8-core 10m open cable and outputs data through both RS-485 and 4-20mA, allowing straightforward integration with plant monitoring and control systems.
Its mid-range measurement span makes it suited to applications where nitrate concentrations exceed the lower-range ST-800 but do not require the ST-802’s high-range capability.
Full-spectrum measurement technology tracks nitrate concentrations from 0-50mg/L in real time, suited to mid-range applications.
Dual RS-485 and 4-20mA outputs connect directly to plant monitoring and control systems.
It measures nitrate from 0 to 50mg/L, a mid-range variant within the Pyxis nitrate probe lineup.
It uses an 8-core 10m open cable and outputs data via both RS-485 and 4-20mA.
It uses full-spectrum optical measurement for continuous, real-time nitrate monitoring.
