GX-3R Pro Confined Space 5 Gas Personal Gas Detector W/ Bluetooth Wireless Communication 72-PAX-C

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.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.

FEATURES:

• Simultaneous detection of 5 gases: LEL; O2; H2S; CO; and other optional sensors; (H2 Compensated CO sensor available).
• Simple 2-button operation.
• Bluetooth communication with iOS & Android App.
• Non-Compliance Indicator.
• 3 user adjustable alarm levels.
• Panic Alarm: Tap instrument twice.
• Man Down Alarm.
• Impact resistant body.
• Large full dot; auto-backlit display with auto-rotation.
• Stealth mode for law enforcement.
• Field replaceable sensors & filters.
• Water and dust resistant design; IP66/68.
• 3 Year Warranty.

APPLICATIONS:

• Personal monitoring.
• Confined spaces.
• Refineries/petrochemical.
• Utilities.
• Oil and Gas.
• Water/Wastewater.
