Nitric oxide detection analyzer

Nitric oxide detection analyzers are mainly used to detect the concentration of nitric oxide in air or liquid. It uses photometry, can quickly produce results within 10 minutes, and is portable and continuous monitoring. This kind of detector is used in chemical industry, oil refining, coking, paper making, painting, medicine and other fields.

Nitric oxide detection analyzers are mainly divided into the following two categories:

1. Active nitric oxide detector: This detector is mainly composed of a light source, a filter, a light detector, a circuit and a display. It is an active instrument, which means that the instrument itself emits light, and then detects nitric oxide in the environment through a detector, by measuring the intensity of reflected light or transmitted light, and then using the reaction principle of nitric oxide and ozone. Calculate the concentration of nitric oxide. This detector has high sensitivity and can be used to measure small amounts of nitric oxide gas.
2. Passive nitric oxide detector: This detector is mainly composed of filter membrane, filter, sampling pump, circuit and display. This kind of detector mainly passively extracts a part of the air, then filters and absorbs the nitric oxide gas in the air, and then converts the absorbed signal into an electrical signal through the photoelectric conversion device inside the instrument, and then passes through the microprocessor Perform data processing to obtain the concentration of nitric oxide in the air. This kind of detector has the characteristics of low price, portability and large size, and is suitable for use in the wild or in some environments with relatively small space.
