Description
Overview
GAOTek portable multi gas detectors are compact full-featured gas detectors for detecting up to four and five types of gases respectively, typically oxygen, combustible gas, hydrogen sulfide, carbon monoxide and VOCs. The key features include an easy-to-operate design, a water-resistant case and high sensitivity sensors.
Features
- Lightweight (less than 300 g) with compact design, easy to operate
- Excellent built-in vibration alarm, ideal for environments with high ambient noises
- 90 dB audible vibration alarm
- Sturdy, protective, concussion-proof shockproof design for normal working in harsh environments
- Easy access to pump, sensors, filter, and battery compartment without exposing electronic components to potential damage
- The rechargeable lithium battery ensures an over 10 hours continuously operation (equipped with a recharger)
- Intuitive simple-to-operate buttons
- User interface with a built-in pump
- 2+2 digits LCD display showing gas concentration and corresponding gas types in real time.
- Full-featured self-test for sensors, lithium battery, circuit integrity and acousto-optic vibration alarm function.
- Accessories: an operator manual, a calibration hose, a recharger, and conversion plug.
