Product details
Portable Formaldehyde Detector - Measurement of Formaldehyde Content in Indoor Air and Building Materials
Portable formaldehyde detectorIntroduction to the Device
The EST-101-CH2O formaldehyde detector is a portable handheld gas concentration measuring instrument designed and produced in accordance with relevant national regulations for natural diffusion gas detection. Adopting high-precision circuit design, the core adopts original imported sensor chips. After being developed and calibrated by Wanyi Technology, signal amplification, calibration, and multiple tests, the product meets the relevant national standard GB_T 18204.2-2014 "Public Place Health Inspection Methods Part 2: Chemical Pollutants" before being released from the factory.
EST-101-CH2O formaldehyde detectorMainly used for:
Medical and disease control public places, occupational health formaldehyde testing.
Indoor environmental testing includes formaldehyde removal, air treatment, and environmental testing.
The interior environment inspection of the car includes seat covers, seat cushions, and roof linings, among other interior decoration materials, with a focus on the new car's formaldehyde emissions.
Formaldehyde is a prohibited additive in food according to national regulations and cannot be detected in food. However, formaldehyde has been detected to varying degrees in many foods
The detection of outdoor air pollution, such as cigarettes, industrial waste gas, automobile exhaust, photochemical smog, etc., can to some extent emit or produce a certain amount of formaldehyde.
Portable formaldehyde detector features:
- High quality sensors with stable and reliable performance.
- External power supply DC5V, built-in rechargeable battery.
- Intelligent design, automatic startup detection, no need for operation, convenient zero adjustment and calibration.
- Supports conversion between ppm and mg/m3 units.
- Can display time and date
- This instrument has the function of viewing weighted concentration values for 1-hour, 8-hour, and intra time periods, which meets the national indoor air quality testing standards.
- Equipped with alarm function, high and low alarm values can be set, two-level sound and light alarms, and 2 high brightness LED lights to remind users to pay attention when an alarm occurs.
- The instrument is compact and lightweight, and can be easily placed in a pocket or bag.
- ISO9001 quality certification, ISO14001 environmental system certification, and can pass national metrology certification.
- Optional sampling pump is available for safe measurement in enclosed spaces such as pipelines, tunnels, and test chambers.
