Inline oil-in-water fluorometer (0-10ppm). 4-20mA + RS-485, 7-pin.

The Pyxis HM-500 is an inline oil-in-water fluorometer designed for produced water, wastewater discharge compliance, and process water monitoring. It covers a 0-10ppm range and outputs via both 4-20mA analog and RS-485 Modbus through a single 7-pin connector, making it suitable for continuous oil-in-water compliance monitoring.
The Pyxis HM-500 is an inline oil-in-water fluorometer designed for continuous monitoring in produced water, wastewater discharge compliance, and general process water applications. It uses fluorometric detection to track oil-in-water concentration across a 0-10ppm range, suited to streams where oil content needs to stay low and well characterized.
The instrument outputs via both 4-20mA analog and RS-485 Modbus communication, delivered through a single 7-pin connector for simplified field wiring. This dual-output approach lets the HM-500 connect to conventional analog control loops as well as networked PLC/SCADA systems.
For operators responsible for produced water handling or wastewater discharge, the HM-500 provides continuous, inline data that supports ongoing compliance monitoring without relying solely on periodic manual sampling.
Covering 0-10ppm, the HM-500 gives produced water and wastewater operations a continuous read on oil-in-water levels to support discharge compliance.
4-20mA analog output combined with RS-485 Modbus lets the sensor communicate with both analog controllers and networked control systems through one 7-pin connector.
It measures oil-in-water concentration using fluorometric detection over a 0-10ppm range.
It is designed for produced water monitoring, wastewater discharge compliance, and general process water monitoring.
Dual output via 4-20mA analog and RS-485 Modbus, delivered through a single 7-pin connector.
Yes, its inline design allows continuous tracking of oil-in-water levels to support wastewater discharge compliance programs.
