Handheld Nitrogen Dioxide Gas Detector Digital NO2 Monitor with Range 0-20ppm
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:
1. Industrial-grade sensor, high precision, real data, strong stability, real-time detection.
2. Triple alarm mode (sound, light, vibration) is not easy to ignore, high security, high and low alarm value can be set free.
3. 7v rechargeable lithium battery, battery capacity 1500MA, charging time is less than five hours, continuous work for more
than ten hours (gas detection is not less than 7 hours).
4. High-strength ABS material, waterproof, dustproof, explosion-proof, three anti-design.
5. The use of mainstream 8-bit micro-control technology, fast response, high precision, stability and repeatability, simple operation, small size, portable and durable, with a high degree of waterproof performance, withstand the harsh environment of the test.
