เครื่องวัดแก็ส Gas Detector Oxygen H2S LEL CO

Watertight design GfG’s G450 is a compact and lightweight 4-gas detector that continuously measures CO, H2S, O2 and combustibles in ambient air. Its functional and watertight design (IP 67) incorporates an impact proof, rubberized housing to meet the toughest requirements of harsh environments.

Easy operation

The G450 simplifies gas detection with three menu-driven soft touch keys. A large graphic display provides accurate readings of all sensors at a glance.

Long life sensors

Factory-calibrated sensors ensure accurate readings. The extended sensor life reduces the cost of ownership. Sensors come with a three year warranty.

Operation time

Depending on the frequency and duration of alarms, the device will operate for up 25 hours. Only 4 hours are needed to fully recharge a unit equipped with the NiMH battery pack.

Perfect alarm system

An extremely loud audible alarm (103 dB at 30 cm) and bright, rotating alarm lights provide a reliable warning for gas hazards. Depending on the severity of the alarm, the display changes color from green to orange or red. The detector’s battery status and readiness for operation are continously monitored and displayed. Critical conditions will cause an immediate alarm. TLV, TWA and STEL values are continuously monitored. A vibrating alarm gives an extra degree of protection in loud environments.เครื่องวัดแก็ส Gas Detector Oxygen H2S LEL CO

Sampling pump

A detachable, self-powered pump is available for sampling confined spaces prior to entry. A low flow alarm is triggered in the event of insufficient flow to the monitor caused by blocked or bent tubing.


The datalogger records gas concentrations and alarms over a period of 50 hours. The data can be downloaded to a PC for viewing, storage and evaluation.

Easy reading

The large, high resolution topmounted display can be flipped 180o by pressing two buttons, allowing measurements to be easily read while the detector is being worn on a belt, pocket or lapel.

Interchangeable battery packs

Rechargeable NiMh or alkaline battery cartridges are easily interchangeable in the field, allowing the user to choose the best choice for their application. The intelligent electronics automatically recognize the type of battery pack installed, allowing the remaining power level to be displayed accurately.
