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 ConfigurationConfirm 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.Why Choose Activated Carbon Depot?Compare RKI sensor part numbers, gas ranges and model compatibility in a single listing to simplify replacement-part selection.
