Hydrogen Analyzer Principle and Introduction
The instrument uses the difference between the thermal conductivity of the component to be analyzed and the background component, and the characteristic of the thermal conductivity of the mixed gas changes with the component to be analyzed. The instrument performs online analysis consisting of a thermally conductive gas sensor and an intelligent signal converter The […]
How to Use Biogas Analyzer?
Open The following inspections and operations should be performed before using the instrument: This instrument is an optical measuring instrument, and the damage to the instrument by dust and moisture in the biogas should be strictly controlled; the sampling head provided by the manufacturer should be connected to the sampling pipeline before measurement, and the […]
How to Debug the Combustible Gas Alarm?
If a metrological certification is required, the portable meter needs to be sent to the local metrology institute, and the fixed meter needs to invite the measurement staff to come to the calibration. (If it is within the range of test accuracy, a metrological verification certificate or test report can be obtained). Learn more about […]
How to Choose the Right Toxic and Harmful Gas Detector?
For various production occasions and testing requirements, choosing the appropriate gas detector is a must for everyone who is engaged in safety and health work. Here we will introduce some specific situations for your reference. Confirm the type and concentration range of the gas to be detected: The types of gases encountered in each production […]
How to Choose Gas Detectors for Different Environments?
According to different environment and testing requirements, choosing the right and correct gas detector is a must for everyone who is engaged in safety and health work. The type of gas detector is different depending on the environment. fixed: This is the most commonly used detector in industrial installations and production processes. It can be […]
How does too Much or too Little Oxygen Harm the Human Body?
What about the oxygen content around you, oxygen detector to protect you! The oxygen concentration in the pure air is 20.95% VOL, then look at how the oxygen is too much to harm the human body: 100% lethal / 6 minutes (absolutely enclosed environment, such as hyperbaric oxygen chamber or deep water) 50% fatal / […]
How does an Environmental Dust Monitor Work?
The working principle of environmental dust monitor, this instrument is composed of a sensor and a data processor assembled together. The sensor is a key component of the instrument’s data acquisition. The principle of this component is to convert the laser beam After a set of aspherical mirrors, it becomes a fine measuring beam with […]
How does a Flammable Gas Alarm Guarantee Production Safety?
Combustible gas alarm device is related to safety, so it belongs to the scope of compulsory verification. Flammable gas alarm instrument has a built-in temperature and humidity sensor, which displays the ambient temperature and humidity in real time. GASTiger 2000’s wireless capabilities allow security personnel to obtain instrument data and alarm status in real-time from […]
How Do Dust Monitors Work?
The working principle of the dust monitor is mainly the principle of light scattering and the principle of electrostatic AC induction. Light scattering principle: The dust meter sucks the aerosol to be tested into the detection chamber through the gas pump. The aerosol to be tested is divided into two parts at the branch, and […]
