VTSYIQI NO2 Gas Detector Portable Nitrogen Dioxide Gas Monitor with Visual and Audible Alarm with Vibration H-alarm 10ppm L-alarm 5ppm Accuracy below 5% F.S. Resolution 0.1ppm Range from 0 to 20ppm for Combustible and Toxic Gas Leakage Detection

VTSYIQI NO2 Gas Detector Portable Nitrogen Dioxide Gas Monitor with Visual and Audible Alarm with Vibration H-alarm 10ppm L-alarm 5ppm Accuracy below 5% F.S. Resolution 0.1ppm Range from 0 to 20ppm for Combustible and Toxic Gas Leakage Detection Introduction: Portable single gas detector can make continuous detection to combustible and toxic gases. It is suitable for combustible and toxic gas leakage detection in underground pipe or mines, and keeps the workers safe, prevents the facilities from being destroyed. The detector, adopting excellent-quality sensor, makes detection in the way of natural diffusion. It has good sensitivity and reproducibility. The detector adopts embedded MCU controller, easy to operate. The shell adopts special high strength material and anti-smooth rubber, with the characters of water-proof and dust-proof. Features: Advanced MCU control with low power consumptionAdjustable low and high alarm level     Adjustable calibrating levelHigh concentration protection
