Terms & Conditions

Can gas sensors or related products be repaired?
Repairs should never be attempted for gas sensors and related products. Instead, they should be replaced.
We are using a finished product manufactured by a third party in which a Figaro gas sensor is installed. For maintenance purposes, can I order replacement/maintenance parts from Figaro?
Figaro sensors are not plug-and-play products. The process of installing a gas sensor into a finished product usually requires the device to be calibrated. Without calibration according to the device maker's instructions, the device may not function as expected and safety may be compromised. Users should not attempt to replace gas sensors unless they can perform this calibration process, which typically involves exposing the target gas. In most cases, calibration is a proprietary process. Please contact the finished product's manufacturer for guidance on replacement/maintenance.
