Formaldehyde Detector- EST-10-Ⅱ-CH2O
The EST-10-Ⅱ-CH2O formaldehyde detector is a portable handheld gas concentration measurement instrument. It adopts a natural diffusion gas detection method and is designed and produced in accordance with relevant national standards and alarm design standards. It adopts high-precision circuit design, with the core using original imported sensor chips. After secondary development, calibration, temperature compensation, signal amplification and stability testing by Wanyi Technology, it is completed. After the standard gas is mixed with a professional gas mixing instrument and the core sensor is calibrated, the product will only be finally released from the factory and delivered to the user after meeting the relevant national standards.
It is mainly used in residences, textiles and food. Artificial boards such as plywood, fiberboard and particleboard used in home decoration materials and furniture contain a large amount of urea-formaldehyde resin mainly composed of formaldehyde, various paints and coatings, and phenolic resin adhesives for artificial boards, such as plywood, fine wood boards, fiberboard and particleboard, etc
Product features
1. Advanced imported sensors, with stable and reliable performance.
2. External power supply: DC5V, with a built-in rechargeable battery. It can be charged simply by connecting to an external power source.
3. The LCD screen can display various parameters, making the data clear at a glance.
4. Conversion between ppm and mg/m³ units.
This instrument has the function of displaying the average values of 5-minute and 15-minute time periods.
6. Intelligent design, built-in temperature compensation, and complete zero adjustment and correction functions.
7. Two-level sound and light alarm, with two high-brightness leds to alert users when an alarm occurs.
8. CE certification, ISO9001 quality certification, ISO14001 environmental system certification, and national metrological certification can be passed.
9. An optional sampling pump is available for safe and stable measurement in enclosed Spaces.
