Concentration and environmental monitoring
Gaseous Hydrogen Peroxide Probe
Local concentration, temperature and relative humidity readings.
The probe measures gaseous hydrogen peroxide over 0–2000 ppm, with a local display for concentration, temperature and relative humidity. Configurable probe addresses support monitoring at different locations.
RS485 / Modbus RTU digital communication and a 4–20 mA analog output support system integration. The probe uses 12–24 VDC power and supports zero and span calibration.
View multiple points together
The independent display terminal is designed to show readings and connection status from multiple monitoring points.
Probe placement can reflect the space layout and monitoring needs. A compatible data-acquisition or monitoring system can show changes at different locations. Supported probe count, display functions and recording arrangements require confirmation for the accompanying system.
Discuss installation conditions and interface requirements for existing equipment and monitoring systems.
Integration and use requirements
Concentration, temperature and humidity readings should be used alongside process records, effectiveness evaluation and site safety requirements. These readings alone do not establish sterilization effectiveness or permission for personnel entry.
