GX-3R Pro Gas Detector
The GX-3R Pro is the world’s smallest 5-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 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 infrared or toxic gas sensors (Hydrogen Cyanide (HCN) and Nitrogen Dioxide (NO2) sensors are currently available for the GX-3R Pro). Two of the four sensor slots have interchangeable sensors providing flexible configurations, which can easily be changed in the field.

Description / GX-3R Pro Gas Detector
Benefits:
Compact and Lightweight: The GX-3R Pro is the world's smallest 5-gas monitor, weighing only 4.58 ounces and fitting in the palm of your hand. Its dimensions are 2.9” W x 2.6” H x 1.06” D, making it highly portable and convenient to carry.
Simultaneous Monitoring: It can simultaneously monitor and display data for 5 different gases, allowing for comprehensive gas detection in real-time.
Wide Gas Range: In addition to standard confined space gases like LEL, O2, CO, and H2S, the GX-3R Pro offers a 5th channel where you can add infrared or toxic gas sensors, such as Hydrogen Cyanide (HCN) and Nitrogen Dioxide (NO2), enhancing its versatility and applicability.
Interchangeable Sensors: Two of the four sensor slots are designed for interchangeable sensors, providing flexibility in sensor configurations. These sensors can be easily changed in the field, optimizing adaptability.
Availability of Additional Sensors: The availability of new toxic gas sensors, such as Hydrogen Cyanide (HCN) and Nitrogen Dioxide (NO2), adds to the options for monitoring hazardous gases.
Bluetooth Wireless Communication: The GX-3R Pro comes equipped with Bluetooth wireless communication, enabling direct gas reading display on a phone app, available for both iOS and Android devices. This feature enhances data accessibility and remote monitoring capabilities.
Man-Down Alarm: The device includes a man-down alarm feature, which can be crucial for worker safety in hazardous environments.
Power Supply Options: Users have the choice between alkaline or rechargeable power supply options, providing flexibility in power management.
Long Battery Life: The Lithium-ion battery pack offers an impressive 25-hour operating time and can fully charge in just 3 hours, ensuring extended use without frequent recharging.
Warranty: The GX-3R Pro comes with a 3-year warranty, offering peace of mind and support for an extended period.
Non-Compliance Indicator: The instrument features a non-compliance indicator that notifies users with flashing LED lights in specific conditions, such as when the instrument has not been bump tested, calibration is due, or there was a gas alarm event. This feature helps ensure instrument reliability and safety compliance.
Adjustable Notification Interval: The 30-second interval for the non-compliance indicator is adjustable, allowing customization to suit specific monitoring needs.
