GfG’s new intrinsically safe G460 is a rugged, compact instrument for simultaneous detection of up to 6 gases. Installed sensor options include infrared (NDIR) for CO2 and PID for VOC measurements. The G460 offers completely automatic calibration, one-button operation, top mounted display and interchangeable battery packs. GfG’s concussion-proof boot, along with the highly dust and water resistant housing protect the instrument in the harshest environments. Datalogging and event logging are standard.

Easy operation

A single on-off button is all it takes for normal day-to-day operation. A simple three button interface provides access to advanced setup options. Calibration adjustment is completely automatic; just attach the calibration adapter and apply gas. The instrument automatically makes adjustments and retains the three most recent calibration dates for each sensor.

Widest range of sensors

G460 detectors are available for use with a wide range of longlasting, interchangeable smart-sensors for LEL, O2, H2S, CO, NH3, SO2, Cl2, PH3, NO2, HCN, EtO, ClO2, HF, O3, NO and H2. Infrared (NDIR) sensors for the direct measurement of CO2, and photoionization detectors (PID) for the measurement of volatile organic chemical (VOC) hazards are also available.

Motorized sampling pump

The motorized pump includes a built-in slide-shutter switch that permits operation in either diffusion or sampledraw mode while the pump is attached. The easily attachable pump is powered by its own battery pack that provides 20 hours of continuous sampling from up to 100 feet away.

Lifetime warranty

The G460 carries a lifetime warranty on nonconsumable components and a two-year warranty on consumable components. O2, LEL, H2S, CO and COSH sensors carry a full three-year warranty against failure.

Datalogging / event loggingstandard

The G460 automatically stores complete results for the most recent 55 hours of monitoring. Any periods during which readings exceed the alarm thresholds are stored as “events” in the permanent on-board memory. Downloading logged information to generate reports and graphs of your monitoring results is easy and automatic with a simple to use data transfer cable.

Innovative easy-to-read displays and alarms

The large, easy-to-read, three-color display changes color to indicate the severity of the alarm; the backlight color changes from from green for "OK" to orange or red for an alarm. The loud audible alarm (103 dB at 12"), built-in vibrator and bright 360° LED alarm indicators alert users to hazardous conditions. The backlit display can be "flipped" 180° or "zoomed" at the push of a button for even easier reading.

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

Interchangeable alkaline and rechargeable (NiMH) battery packs provide up to 25 hours of continuous operation. The drop-in cradle charger fully charges a depleted battery pack in less than 4 hours. The cradle includes LEDs to indicate fast charge / trickle charge status.

Built-in "flash light" LEDs

G460 detectors can be equipped with built-in high intensity "flash light" LEDs.
