The SE230K and SE233K are gas detectors for methane and LPG that advices with an optical and acoustic signal the presence of gas in the environment.

The SE230K/SE233K detectors are calibrated to notice existent gas in the environment up to 10% less from the explosion concentration L.E.L. (Low Explosion Limit), this threshold can change following the environmental conditions but it will not be over passed, during the first 4 years of use of the 15% L.E.L., after that period the instrument have to be put out of order or resend to Tecnocontrol S.r.l. for a complete substitution of the device.

With that aim, the package is provided with a printed label on were is indicated the correct working period (4 years from installing date); this printed label have to be filled from the installer on the frontal panel of the detector during the installation.
