Gas Sensors (replacement)

We offer gas sensor replacements for our most popular models. All sensors are pin-to-pin replacement and the majority are 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.
