G450 Multi-Gas Detector from GfG Instrumentation

The G450 Multi-Gas Detector, continuously measures and displays readings for up to four gases at the same time including LEL, O2, CO & H2S. The GfG G450 portable gas detector is compact, robust and very easy to use. The dust proof and highly water resistant (IP-67) housing is designed to survive the toughest environmental conditions. The housing even includes a built in rubberized boot to withstand the hard knocks of confined space entry.

Dependable and accurate G450 sensors keep the cost of ownership down. All sensors – including O2, LEL combustible, CO and H2S sensors – carry a full three year warranty from the date of purchase.

The G450 keeps combustible gas detectors simple. Most day to day functions are controlled with a single button and calibration is fully automatic. Simply attach the adapter and flow gas to the sensors. GfG Autocal programming automatically makes the adjustments and updates the information in the instrument’s on board memory.

G450 battery packs deliver up to 25 hours of continuous operation. Alkaline packs are powered by two “AA” batteries. Rechargeable battery packs can be completely recharged in less than four hours in the drop in cradle charger. Rechargeable battery packs can even be equipped with optional “flash lights” LEDs.

Whether it’s worn on your belt or held by hand, the G450 is easy to read. The top mounted, full graphics LCD includes a built in backlight for use in the dark. Readings can be zoomed or flipped at the push of a button to make it even easier to see your monitoring results.

The G450 includes an extremely loud audible alarm (103 dB at 12″), built in vibrator and bright wrap around LED alarm lights visible from every direction. The top mounted display changes color from green to orange to red just like a traffic signal to help communicate the severity of the hazardous condition.

The field attachable motorized pump is powered by its own alkaline or rechargeable battery pack. The powerful diaphragm pump is equipped with an on/off shutter that allows the instrument to be used in diffusion mode even while the pump is attached.

All G450 instruments are equipped with datalogging. The datalogger records gas concentrations and alarms on moment to moment basis. Monitoring results can be downloaded to a PC for viewing, storage and evaluation.

Each G450 comes complete with sensors and battery pack (as specified), cal adapter, manual and training DVD. Rechargeable instruments additionally include a drop in cradle charger and wall power adapter.
