Portable flammable gas detector GOFL
The GOFL detector is an instrument designed to detect the leakage of flammable gases into the air in a normal environment. Its main features advantages are easy operation, simple use, small size and good mechanical resistance. The instrument allows the setting of a concentration level, the exceeding of which is indicated by an uninterrupted beeping sound.
A catalytic sensor is used as the detection sensor, which responds to a wide range of combustible gases. The instrument is calibrated to methane as standard and, due to the known sensitivity of the sensor to other gases, allows switching between a methane value or a converted propane value. The instrument is equipped with a backlighted display which shows the current concentration value of the gas being detected. The value is displayed in units of \%LFL (percent lower flammable limit) and in units of ppm. The battery status is also indicated.
A battery is hardwired into the GOFL detector to power the instrument. Recharging of the internal battery can be done using a standard adapter with a USB-C connector.
