Portable Automatic Monitoring Instrument Air Quality Automatic Monitoring System

Portable automatic monitoring device

With the rapid development of industrialization and the sharp increase in population, the increasingly deteriorating environment has attracted high attention from countries around the world. In recent decades, the severity of global environmental issues has directly threatened the economic and social development of countries around the world. Air pollution incidents have damaged the health of residents. Abnormal weather conditions such as acid rain across regions and rising carbon dioxide concentrations in the atmosphere have begun to seriously affect the world's crop and food supply. A portable distribution network automatic monitoring device has been disclosed, comprising a protective box and a monitoring device body. The upper and lower sides of the protective box are symmetrically provided with cavities, and buffer mechanisms are installed in all four cavities. The portable turbidity, suspended solids, and sludge interface monitoring device is an ideal remote monitoring tool for municipal and industrial wastewater, drinking water, and river monitoring. This instrument can be used as an optimization tool in the monitoring process, as well as a convenient method for calibrating or verifying online sensors. The instrument is mainly controlled by a microcontroller and has the characteristics of automatic gain adjustment, automatic acquisition, and automatic storage according to the size of the input signal; At the same time, it also has the ability to automatically recognize signals and prevent accidental triggering.

Portable automatic monitoring device

Features and advantages:
1. One instrument can measure three parameters;
2. Multiple calibration curves for easy use;
3. Convenient measurement of sludge interface;
4. Bubble compensation measurement ensures higher accuracy;
5. Durable material with long service life;
6. Use rechargeable batteries for power supply;
7. The composite multi beam alternating light method with an infrared diode system using * is adopted,
Whether measuring turbidity or suspended solids, the measurement range is relatively wide.

Easy operation

Considering the simplicity of operation, a single gas detector usually has only one button, while multiple gas detectors often have three buttons. For the practical operation of workers, the button design is relatively large and can be easily operated even with gloves.

The readability of the screen is also an important factor, and a large display screen size is preferred. If LCD display technology is used, it is more flexible and clear than LED. The latest model of Meisi An, "Tianying 5", can even choose a color screen. "Tianying 4X" has a luminous shell, which is very convenient to use in limited spaces or other places with insufficient light.

Long life sensors

Sensors are the most important and expensive components in portable gas detectors. The accuracy of the instrument depends on the sensitivity of the sensor. The lifespan of sensors is usually 1 to 2 years.

According to the detection principle, sensors are divided into semiconductor, electrochemical, catalytic combustion, photoionization (PID), and infrared sensors. Different gases to be tested generally use fixed types of sensors.

A good sensor has fast response, sensitive readings, strong anti-interference ability, good repeatability, saves calibration gas, and the lifespan of the sensor directly affects the cost of use.

Long operation time

The operation time of a portable gas detector depends on the battery's operating time. There are dry batteries or rechargeable batteries, as well as two types of instruments that complement each other. Currently, the longer operating times on the market are 16 hours and 24 hours, which can be used by workers for two shifts. The actual application time may vary depending on the frequency and duration of the alarm.
