Formaldehyde alarm is a device used to detect formaldehyde content in the air, when the formaldehyde concentration exceeds the preset alarm value, the alarm will send out an alarm. The formaldehyde alarm is mainly composed of a formaldehyde gas detector and a gas alarm controller, the detector is responsible for detecting the formaldehyde concentration, and the controller is responsible for receiving the signal of the detector and triggering the alarm.
The main performance characteristics of the formaldehyde alarm include:
1. Alarm storage memory: the formaldehyde concentration value at the time of the alarm can be recorded to facilitate subsequent traceability and analysis.
2. Historical record query function: you can query the past formaldehyde concentration data to understand the changes in indoor formaldehyde content.
3. Permanent clock display: the current time can be displayed in real time, which is convenient for users to know the time when the alarm occurs.
4. Main and standby electric conversion: when the main power supply fails, it can be automatically switched to the standby power supply to ensure the normal operation of the alarm.
5. Backlit LCD screen display: It can be clearly displayed in a dark environment, which is convenient for users to view.
6. Each detection point can be set independently: different alarm values can be set according to needs to meet different application scenarios.
7. Automatic fault diagnosis of each channel: It can automatically detect the working status of each channel, find the fault in time and prompt it.
8. Sound and light alarm: When the formaldehyde concentration exceeds the preset value, the alarm will send out an sound and light alarm to attract the attention of users.
9. Accurate measurement: high-precision formaldehyde sensor is used to ensure the accuracy of measurement data.
10. Explosion-proof design: It can be used in dangerous occasions such as factories to ensure the safety of equipment.
11. Easy maintenance: The sensor adopts digital module design, which does not need to be calibrated and calibrated when replaced on site, which is convenient for maintenance.
12. Sound and light alarm: special explosion-proof sound and light alarm can be selected to realize on-site sound and light alarm.
Precautions for the installation of formaldehyde alarms include:
1. The detector should be installed 30 60cm from the ground, and the sensor part should be downward.
2. The controller should be installed in the duty room or office, and the detector should be installed at the testing site. When the on-site gas concentration reaches the preset alarm point, the detector gives a signal to the controller, starts the sound and light alarm function, and turns on the exhaust fan or solenoid valve.
3. The mounting plate can be fixed on the wall with 6 plastic expansion plugs, and the mounting hook on the back of the controller can be hung on the mounting plate.
