The GX-3R Pro is the world’s smallest 4-gas monitor weighing only 4.58 ounces and fits in the palm of your hand (2.9” W x 2.6” H x 1.06” D).

It simultaneously monitors and displays 4 different gases. In addition to monitoring standard confined space gases, LEL, O2, CO, & H2S, the GX-3R Pro has a 5th channel where you can add infrared or toxic sensors.

Two of the four sensor slots have interchangeable sensors providing flexible configurations, which can easily be changed in the field.

GX 3R Pro Intro Features & Benefits

The GX-3R Pro comes equipped with Bluetooth wireless communication, a man-down alarm, the choice of alkaline or rechargeable power supply, and a 1-year warranty.  The Lithium-ion battery pack will operate for 25 hours and will fully charge in 3 hours.

The GX-3R Pro utilizes Bluetooth communication to display direct gas readings from the instrument to a phone app, which is available free on either iOS or Android phones.  Automatic notifications can be programmed to send text or email messages if there is an alarm event from the GX-3R Pro.

Ideal for:

  • Personal monitoring
  • Confined spaces
  • Refineries/petrochemical
  • Utilities
  • Oil and Gas
  • Water/Wastewater
  • Fire Services
  • Construction

Safety supervisors will appreciate the non-compliance indicator. The instrument flashes its 3 LED lights every 30 seconds in the following conditions; if the instrument has not been bump tested, or if calibration is due, or if there was a gas alarm event. The 3 LED lights will continue to flash once every 30 seconds until the non-compliance condition has been resolved. The 30-second interval is adjustable.

Our GX-3R price is highly competitive and adapted to Canadian market.

QUICK TIP:
Measuring Mode Operation
When the GX-3R completes its startup sequence, it is in Measuring Mode. In Measuring Mode the GX-3R continuously monitors the sampled atmosphere and displays the target gas concentrations. The GX-3R is considered to be in Normal Operation if there are no alarm indications.
Heart Symbol: The heart symbol in the upper left corner of the LCD indicates the operation status and blinks when normal. A microprocessor error causes the heart symbol to stop flashing or to disappear.
Check Mark: If BUMP.RMDR is set to ON and if a bump test is not due, a check mark appears in the upper left corner of the LCD.
“S”: If the instrument is operating in Stealth Mode, an “S” appears at the top of the LCD.
Backlight: In a low-light environment, press and release either button to turn on the display backlight.
Confirmation/Non-Compliance Indicator: If the BEEP menu item in User Mode is set to anything other than OFF, the GX-3R gives periodic indications to confirm that it’s operating or to indicate a non-compliance.
