Overview:
The GX-3R Pro is the world’s smallest and lightest five gas personal monitor, weighing only 129 grams and fits in the palm of your hand (73 W x 65 H x 26 D mm). It simultaneously monitors and displays up to 5 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 ppm or % volume CO2 or SO2. A H2 compensated carbon monoxide sensor is also available. Two of the four sensor slots have interchangeable sensors providing flexible configurations.
Furthermore, the GX-3R Pro 5 gas personal monitor comes equipped with Bluetooth wireless communication, a man-down alarm, the choice of alkaline or rechargeable power supply, and a 3-year warranty.
Lithium-ion battery packs will operate for 25 hours and will fully charge in 3 hours. So, this can be put into long-life battery mode and operate up to 40 hours.
Bluetooth Communication
Also, the five gas personal monitor utilises Bluetooth communication to display direct gas readings from the instrument to a phone app, and it is available free on either iOS or Android phones.
Alarm Notification
Automatic notification can be programmed to send text or email messages, if there is an alarm event from the GX-3R Pro.
Safety supervisors will appreciate the non-compliance indicator, because the instrument will flash its 3 LED lights every 30 seconds, if the instrument has been exposed to a gas or has not been bump tested or calibration is due.
Additionally, the 3 LED lights will continue to flash once every 30 seconds until the non-compliance condition has been resolved. It will also gas a tick which is visible on the screen to confirm a bump test has been carried out.
