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.

4G Wireless Temperature and Relative Humidity Datalogger with flood detector
he U3832G datalogger is used to measure temperature, relative humidity and dew point temperature using internal sensors, plus an attached LD-81 flood detector to indicate water flooding. In case of exceeded set limits, SMS and JSON messages can be sent via 4G data connection. Measured values can be sent to the internet storage COMET Cloud, which is a complete monitoring, alarm and analysis system.
It is also possible to set the regular sending of JSON messages to COMET Database, the sending interval is adjustable. Alarms are also indicated locally by LED, LCD and acoustically by built-in beeper.
The recording is performed in a non-volatile electronic memory. The data can be transferred to a PC via included USB-C cable.
GSM recorder includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
