Portable formaldehyde testerIt is a portable device used for rapid detection of formaldehyde concentration in the air, widely used in indoor environmental monitoring, furniture detection and other fields.

Working principle: Electrochemical sensing technology is usually used. Through electrochemical sensors and high-precision operational amplification chips, the formaldehyde concentration signal in the air is directly converted into an electrical signal in real time and continuously. After data processing by a microcomputer, the measurement results are displayed in LCD digital format.

Features:

Strong portability:Portable formaldehyde testerCompact in size, lightweight, easy to carry, and capable of formaldehyde detection anytime and anywhere.

Intuitive display: Generally equipped with a large LCD screen, it can clearly display the instantaneous value, peak value and other information of formaldehyde concentration. Some also have backlight function, making it easy to view in different environments,.

Alarm function: It has sound and light alarm function. When formaldehyde concentration exceeds the set safety threshold, it will emit sound and light prompts to remind users to pay attention.

Easy to operate: Usually operated with simple buttons or touch screens, it can be used without complex training, and some instruments have a power on self-test function to ensure normal operation.

Fast detection speed: Short response time, able to quickly provide detection results.

Precautions for use:

Calibration and maintenance

Regularly calibrate with standard gas (recommended every 3 months) to avoid sensor drift.

Choose original accessories when replacing sensors to prevent compatibility issues.

Environmental interference avoidance

Close doors and windows for 12 hours before testing to avoid ventilation affecting the results.
