Tips: Common Types of Formaldehyde Detection

Common formaldehyde test instrument in the market can be broadly divided into the following categories:

1. One of the CH2O gas detector uses the probe for testing. It is characterized by direct reading of data and easy to carry.
2. Another test instrument is the use of spectrophotometry to analyze the reading. This kind of instrument has a more prominent characteristic - high accuracy, has little interference from other gases, and has temperature and humidity compensation.
3. Portable formaldehyde gas detector is an instrument that can continuously measure formaldehyde. This product is suitable for environment monitoring, industrial production, chemical industry and other places with formaldehyde.
4. Handheld HCHO monitor can be zero calibrated on the site under test without the help of outdoor air. It is applied to the detection of formaldehyde gas in public places, civil buildings and building materials.

Calibration of Portable Gas Detector

This video will show how to calibrate the ATO portable gas detectors.

Concentration Detection of Pesticides Gas
Methyl bromide is an organic compound with the chemical formula CH3Br, which is mainly used as a pesticide, fumigant, refrigerant and solvent, and can also be used in organic synthesis.This video will mainly use methyl bromide and CH3Br as examples to introduce the detection of their concentrations.

How to Detect Hydrogen Sulfide Concentration in the Toilet
Hydrogen sulfide is a flammable acidic gas that smells like rotten eggs at low concentrations and is very toxic. In actual operation, it is necessary to ensure that the detection equipment or method used can accurately measure the concentration of hydrogen sulfide, and pay attention to safety issues during operation to avoid hydrogen sulfide poisoning.

How much C2H4 (ethylene) do ripe bananas and apples produce?
We have various gas detectors such as: CO, O2, O3, H2, NH3, H2S, CH4, Cl2, CH2O, etc, from 0~10000ppm, Industrial or daily use.
