Description
Overview
GAOTek handheld hydrogen multi sensor gas leak detector is a portable gas and dust detector which can be configured flexibly up to 5 gas sensors or 3 gas sensors plus 1 dust sensor. With import gas sensor and most advance nanometre semiconductor technology this detector can detect corresponding gas and dust concentration at the same time rapidly and precisely maintain a leading position in domestic level and our products are famous for high stability and repeatability. User can customise all parameters to ensure the operations are user friendly. 4000 mA built-in high-capacity polymer rechargeable battery, technical indicators, gas concentrations and historical data can be displayed in the 3.5 in IPS technical grade screen. User can save concentration data, output data, print and output data, detect temperature and humidity level.
