Notes on Using Gas Detectors

The gas detectors sensor determines the sensitivity and accuracy of the detector, so we should pay attention to the sensor of the gas detector when we buy it. Some gas detectors are small, portable, and powerful. They can also detect the concentration of various gases, therefore placing high demands on the sensors of the gas detectors.

Because the gas detector needs to detect the concentration of various gases, it is necessary to calibrate and test the gas detector regularly. In addition, there is a waiting period before the gas detector gets an accurate test value. If the gas detector is not calibrated and tested as necessary in a timely manner, it will affect the subsequent test value.

Gas Detector Probes

Each type of gas detecter has its corresponding sensor, which means that the gas detector sensor has a certain uniqueness.

When we choose each gas detector, we should pay attention to the influence of other gases on the sensor. Therefore, we should first understand the interference of other gases on the sensor, which can improve the accuracy of the detector.

In addition, we should pay attention to the reasonableness of the gas detection instrument in appearance design for better gas detection.

TC-700 Multi-function gas detector

TC-700A can detect PM2.5, PM10, CO2, TVOC, HCHO, AQI, TEMP, RH.
The TC-700 sensor detects CO2 present in the air using the non-dispersive infrared (NDIR) principle.
PM2.5 by laser scattering principle and AQI detects environmental quality.
PM2.5 and PM10 concentration. Temperature and humidity detection, using imported sensors.
In life, gas detection instruments are widely used, not at home, hospitals, public places, and even industrial production, breeding animals will be used. Gas detection instruments play a huge role.
TC-700 portable gas detector operation is very simple, but the use of some related issues needs attention.

Gas Detector Detection Range

Generally speaking, any gas detection is required to have a fixed detection range, so it is the same TC-700 portable gas detector. It can only be within its range to complete the measurement work. Otherwise, the measured results will be inaccurate, and if beyond its range detection, the gas may cause some damage to the sensor, the consequences of this will make it impossible to detect the correct results.
For example, the TC-700 has a CO2 measurement range of 370-9999 PPM, and if the CO2 concentration in the test area exceeds the range, it will not be measured. Of course, the range is basically not exceeded for either household or industrial use.

Service Life

You also need to pay attention to its service life for this detector. Generally, too much use or infrequent use will lead to its performance aging. GAS DETECTOR service life of more than 10 years, using high-precision imported sensors and high-quality raw materials.
In fact, many portable gas detectors on the market only have a few years of life. It means that the buyer has to replace the CO2 detector after a few years of purchase, increasing the economic cost.

Power Supply

TC-7000 gas meter monitor uses rechargeable lithium batteries or separate external USB power supply, ultra-long working time, and standby time. This operation is very convenient.


Wall Mounted Multi function Gas Detectors

TC-700, in the appearance of the above design, is very clever. There is a bracket and wall hole on the back, so that it can be placed on the table or hung on the wall. It can adapt to the requirements of a variety of placements. Small size, does not take up too much space.


TC-700 temperature and humidity sensor is located at the top of the detector, to avoid the heat of other sensors during operation affecting the detection of temperature and humidity. The sensor is located at the top, but also just the detection of gas temperature and humidity.
TC-700 above multiple gas outlets and air inlets, to ensure the scientific detection of multiple gases and gas values to achieve high accuracy.

This testing instrument is developed by engineers with many years of work experience, robust, stable, and very high-cost performance.
