These are our replacement H2S gas sensors for Forensics Detectors Hydrogen Sulfide gas detector and gas analyzer products. These are generic H2S sensors used as the pin-to-pin replacement of the standard 4-series electrochemical sensors. Once replaced, please undertake the appropriate calibration. An alternative is to send us your gas detector unit. Purchase the replacement gas sensor and the gas detector calibration service. Once received, we will replace the sensor for FREE and send the gas detector back to you with a new calibration certificate.
