Product Description

Veinasa-HCHO Formaldehyde Detector Pollution Meter Formaldehyde Sensor 

Product Description

 

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.

Wiring Method

1. When DC power is supplied, the "VCC" terminal is the positive pole of the power supply and the "GND" terminal is the negative pole of the power supply. Please pay attention to the polarity of the power supply when powering on. If the positive and negative connections are reversed, the sensor will not work properly, but it will not damage the sensor;
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.

Application Fields

Suitable for modern buildings, smart air conditioners, chemical plants, furniture factories, subways, airports, schools and other places.

FAQ

Q: Are you a factory/manufacturer?

A: Yes, we are professional factory/manufacturer of weather station and relative weather sensors. We also have hot sale and widely used weather station AWS005S.

Q: What's the common power supply and signal output?
A: Common power supply and signal output is DC12-24V, RS485. But we can customize for you as demands.

Q: How can I collect data?
A: If you have your own data logger, you only need to buy our sensor and meanwhile we send you communication protocol.

If you do not have, we can add our data logger for you, also provided with English software, which can help you read, inquire and download data.

Q: What's the lifetime of this air quality monitoring equipment?
A: At least 5 years long. Every sensor has its own calibration certificate or testing report.

Q:What's the delivery time?
A: Usually, we dispatch goods in 3-5 working days after receiving your payment. But it depends on your quantity.

Q: May I know your warranty?
A: Yes, usually it's 1 year. We can send you detailed warranty document if needed.
