Veinasa-HCHO Formaldehyde Detector Pollution Meter Formaldehyde Sensor
The formaldehyde transmitter is small, soft and beautiful in appearance. It uses a PC engineering plastic case with an internal high-precision electrochemical formaldehyde sensor as a sensitive sensing element. It is equipped with a dedicated IC processing chip and a new type of compensation operational amplifier circuit. The formaldehyde concentration data is converted into a corresponding standard signal.
Formaldehyde transmitter has the characteristics of small size, light weight, high accuracy, high linearity, fast response speed, good long-term stability, etc.
It is a professional formaldehyde concentration measuring device.

2. For AC AC power supply, the "VCC" terminal and the "GND" terminal do not distinguish between positive and negative polarity. However, it is recommended that the "VCC" terminal be connected to the live wire and the "GND" terminal to be the neutral wire for consideration of electrical installation specifications.
3. "GAS" terminal is the output terminal of formaldehyde measurement voltage signal.
Suitable for modern buildings, smart air conditioners, chemical plants, furniture factories, subways, airports, schools and other places.
