The GX-Force can detect flammable gases, Oxygen and toxic gases (Carbon monoxide and Hydrogen sulphide), quickly and reliably using built-in pump aspiration. The CO/H2S dual sensor enables the number of sensors to be reduced from four to three, and the dimensions and weight have been downsized (approx. 280 g (-22% compared to the previous version)), leading to lower cost and ease of use.
The GX-Force can be used for confined space, safety monitoring in its Normal Operating mode. A Leak Check mode is the solution for all leak investigations. The GX-Force can monitor the standard confined space gases (LEL combustibles, Oxygen content, Carbon Monoxide, and Hydrogen Sulphide). Built around high-quality micro-sensor technology, which are compatible with the GX-3R, GX-3R Pro, 04 Series, and Gaswatch 3 instruments.
In Leak Check Mode, the GX-Force, can monitor for combustibles in the ppm range.
The GX-Force's large LCD display shows all gas readings, battery level, current time, and will automatically backlight in alarm conditions. Standard alarm types include vibration, visual, and audible alarms, which can be set to latching or non-latching. Controlled by a microprocessor, the GX-Force continuously checks itself for sensor connections, low battery, circuit trouble, low flow, and calibration errors.
