Choose the Right Replacement Sensor
- Standard gas options include LEL, O2, H2S, CO, hydrogen-compensated CO and combination CO/H2S sensors.
- PID choices include 10.6 eV lamps for 0-40 ppm or 0-4000 ppm VOC measurement, a 10.0 eV VOC/benzene option and an 11.7 eV VOC option.
- Infrared options include auto-ranging methane and hydrocarbon sensors plus CO2 sensors in ppm or percent ranges, with selected scrubber versions.
- Specialty options include NH3, HCN, Cl2, MMH, NO2, SO2 and PH3 sensors.
- TE-7561 provides TC percent-volume measurement. SH-8661 is the MOS ppm plug-in portion only.
Installation and Configuration
Confirm your monitor supports the selected sensor and measurement range before purchase. A replacement sensor alone does not convert an instrument to a different gas configuration. Benzene-specific PID operation requires the correct configuration and pre-filter accessories. Follow the applicable RKI manual for installation, calibration and functional testing before returning the monitor to service.
