VTSYIQI Portable Ammonia Gas Detector NH3 Gas Detector NH3 Gas Leakage Alarm Monitor with Measuring Range 0-100ppm Accuracy ≦ 5% F.S. Resolution 0.1/1ppm for Coal Mine Shipping Gas Detection

VTSYIQI Portable Ammonia Gas Detector NH3 Gas Detector NH3 Gas Leakage Alarm Monitor with Measuring Range 0-100ppm Accuracy ≦ 5% F.S. Resolution 0.1/1ppm for Coal Mine Shipping Gas 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 for combustible gasSelf test for the combustible gas sensorLow battery indicationSelf-adjustment functionVisual and audible alarm with vibrationAdvanced self-examination and self-renovation functionPassword management to avoid wrong operationExplosive proof housing Specifications: Accuracy:≦ 5% F.S.
