1. Product Overview
Hand-held formaldehyde monitors use electrochemical sensors and high-end microprocessors that provide a continuous, real-time digital display of air formaldehyde concentrations on liquid crystals. They are well suited to provide 24-hour constant real-time monitoring of indoor formaldehyde concentrations.
The high-sensitivity, formaldehyde monitor model is designed to look good, operate easily, and provide comprehensive care for your health and that of your family.
Scope of application: indoors, office premises, cars.

Domestic formaldehyde monitors, a completely new indoor formaldehyde concentration monitoring instrument, break the technical bottlenecks in the use of traditional formaldehyde detectors, which are cumbersome, costly and can only be tested once, using the latest imported electrochemical sensors and high-precision amplification chips, conversion of signals of formaldehyde in air directly into telecommunications in real time and continuously, and displaying measurements in LCD digitally after data processing through microcomputers. Monitors are designed to look good, operate easily, and provide comprehensive care for the health and safety of you and your family.
Precautions for use
(1) The screening of windows, doors, and so forth is done 10 minutes before the screening of spaces such as bedrooms, living rooms, and cloakrooms.
(2) The product is sampled in a free circulation mode of air, with a certain response time when the product is moved from room A to room B for testing, and after a steady reading of about three minutes, the detected value is the value of the formaldehyde at the detection point.
(3) Any sensor works with a certain amount of external substance, so when using this product for testing, avoid exposure to alcohol substances such as alcohol, perfumes and high concentrations of HS, CO, SO, H, fumes, etc.
(4) The product is based on a diffuse sampling method of free circulation of air, indoor air is in circulation at all times, air entering the sensor ' s sample window at different points of time, and the level of formaldehyde in the air may vary, so it is normal to monitor a small amount of floating up or down.
(5) Please do not blow directly into the sensor or block the sensor window, which would interfere with the normal work of the product.
(6) Please do not place this product in a high concentration of formaldehyde that is beyond the scope of measurement, which would otherwise cause damage to the product.
Note: If a bluetooth version is required, an additional $100 will be required, and we will provide a description of the data format.
