Cnh500/50 No2&No Gas DetectorCN500/50 NO2&NO gas detector is an intrinsically safe and explosion-proof instrument and is designed to detect the NO2 & NO in the coal mine environment. With imported electrochemical sensor, it is sensitive and high accuracy. Compact size and lightweight make it easy to carry in the pocket or safety helmet. With its shockproof, t is protective and durable in use.
It is used at the underground coal mine and routine mine safety inspection mainly. Certainly, it is also applied to fire fighting, confined space, chemical industry, oil and all kinds of environment that needed to measure the NOx.

Features:
1. Imported electrochemical sensor
2. Compact size, lightweight, easy to carry
3. High brightness OLED screen
4.1500 Am polymer lithium battery
5. Alarm when high concentration, over-range and low power
6. LED alarm light with buzzer
7. High strength ABS material
8. MA, Explosion proof and CMC certificates available.

Sodium Hydrosulfite

Sodium hydrosulfite is widely used in the textile industry for reducing dyeing, reducing cleaning, printing and decoloring, and for bleaching silk, wool, nylon and other fabrics. Because it does not contain heavy metals, the bleached fabric has bright color and is not easy to fade. In terms of various substances, sodium silicate can also be used for food bleaching, such as gelatin, sucrose, honey, etc., soap, animal (vegetable) oil, bamboo, porcelain clay, etc. Sodium hydroxide can also be used in organic synthesis, such as reducing agent or bleaching agent in the production of dyes and medicines. It is the most suitable bleaching agent for wood pulp and papermaking. Moreover, many heavy metal ions such as Pb2+ and Bi3+ can be reduced to metals in water treatment and pollution control, and it can also be used to preserve food and fruits. However, due to the many dangers of sosso, many of its uses tend to be replaced by thiourea dioxide, which is safer and easier to store and transport.
