This Gas Detector is a unique gas meter which protects against a specific gas, inflammable or toxic. The Gas Detector Gasman warns with a penetrating alarm and an optical signal (useful when there are loud noises in the surrounding area) of the existence of dangerous gas concentrations and shows on screen the value of the gas measurement. In addition with this gas meter you are able to save measurements and transmit them onto the computer for evaluation. For that, it is necessary to require the additional option of data logger and optional software. The function of logger will allow you to keep all the values in the meter with a quota of measurement from 1 minute to a total of 900 hours. The data saved in the apparatus can be, at any time, transferred onto the computer or laptop for later evaluation. The Gas Detector can be calibrated and certified according to DIN ISO.
