Humidity Analyzer

http://www.zetian-group.com/products/humidity-analyzer/

ZETIAN humidity test meter has a built-in high-precision capacitive digital temperature and humidity sensor.

 The accurate humidity meter can be used to measure the humidity of flue gas pollution sources. Based on the measured humidity, the moisture concentration is converted to dry gas concentration. In addition, it can also be used for industrial online humidity monitoring.

 With the development of the times, scientific research, agriculture, HVAC, computer room, aerospace, electric power and other industrial sectors have higher requirements for product quality, and the more they need to use humidity test meters, control of environmental humidity and industrial materials. The monitoring and analysis of moisture value have become one of the more common technical conditions. Continuous emission monitoring system suppliers like ZETIAN meets all your requirements.

 1. The application of humidity analyzer in the pharmaceutical industry

The important links related to humidity in the pharmaceutical industry require comprehensive and reliable products and solutions, such as the storage environment monitoring of pharmaceutical raw materials, the verification of the sterilization and sterilization process of pharmaceuticals and pharmaceutical machinery, the monitoring of the pharmaceutical transportation environment, the laboratory purification workshop environment and equipment monitoring, etc.

 2. The application of humidity analyzer in the cold chain logistics industry

Vaccines need to be refrigerated, and their storage humidity also has certain requirements. In fact, there are more biological products that have strict requirements on the storage and transportation environment, such as plasma, blood products, biological agents and so on. These fields related to life sciences have higher requirements for equipment, like precision humidity meter, than other industries.

 3. The application of humidity analyzer in the industrial and electronic industry

The industry is mainly geared towards epoxy resins, high-end composite materials, precision microelectronics, integrated chips, optoelectronic components and other fine chemical products, such as epoxy resins and high-end composite materials.

 During storage and transportation, there are special requirements for environmental temperature and humidity conditions and severe vibrations. This is why high temperature gas analyzer has become more and more important. If some parameters are not properly controlled, the quality of the product will be unstable and even waste products will be produced.

 Humidity is the deadly enemy of the quality of electronic products, and most electronic products require operation and storage under dry conditions. According to statistics, more than a quarter of industrially manufactured defective products are related to the hazards of moisture each year in the world.

 For the electronics industry, the hazard of moisture has become one of the main factors affecting product quality. Such as integrated circuits, liquid products, silicon wafers, electronic devices during operation and finished electronics, etc., if stored for too long in a high humidity environment, some pads and chip pin surfaces will be oxidized, resulting in poor contact and failure.

 Companies in the chemical electronics industry should focus on managing the temperature and humidity of raw material warehouses, production workshops, finished product warehouses, and transportation processes to provide decision-making basis for quality stability.

HM-100 High-temperature Hygronom

Overview

Hygronom is also called moisture meter or dew-point meter, which is used to measure the humidity of flue gas emitted by pollution source. According to measured humidity, it converts wet gas concentration into dry gas concentration. In addition, it also can be used in industrial online humidity monitoring.

It is a self-developed product, of which, the core component is from Switzerland. Put the sensor inside stack to get in touch with flue gas. The probe needs preheating to prevent gas from condensation, which will affect the measurement of moisture in the flue gas. After gas contacts with the measurement chip, the chip will change capacitance to measure flue gas concentration.

EQMS VOCs Online Monitoring System

Volatile Organic Compounds (VOCS) are carbon based compounds that pose a significant health hazard due to their toxicity. VOCs online monitoring system adopts PIO (photoionization detector ) for gas detection. The target gas is irradiated I bombarded by ultraviolet light produced by the ion lamp, and is ionized after absorbing enough uv energy. The concentration of the target gas can be detected by detecting the tiny current generated after the ionization of the gas.

 The system consists of sampling unit, condensing unit, zeroing unit, calibration unit, display unit, pressure alarm unit and analysis instrument. The sample gas enters into the PIO under the action of filtration and condensation of the suction pump. The detector transmits the processed concentration signal to the display unit, the end user, and the EPA platform. The user can set the auto zeroing and calibration period according to the actual situation. While the pressure alarm unit outputs a pressure alarm signal when the injection port of the analysis instrument is blocked, prompting the end user to clean the filter in time.
