Standard value of formaldehyde concentration: 0.1 mg / m3.(Refer to GB/T 18883-2002)
Formaldehyde detector has high power consumption due to guarantee the detection accuracy and sensitivity, the program needs to process a lot of complicated operations, which costs much usage of electricity. Turn off the power when detection ends to avoid waste of electricity
i) 1~3 locations should be detected when the area is less than 50 m2; 3~5 locations should be detected when the area is between 50 m2~100 m2; at least 5 locations should be detected when the area is larger than 100 m2. All the detection locations should be distributed on the diagonal or in quincunx form.
ii) detection locations should be kept away from an air vent, and at least 0.5 m far away from walls.
iii) height of detection locations are comparable to the height of a human, relatively between 0.5~1.5 m
1. The sensor of the detector may be affected by external disturbance just like all the other high precision apparatuses, so contact with ethanol, perfume or gas like H2S, CO, SO2 and smoke should be avoided.
2. When the detector is working, avoid straight wind flow from electric fans, warm air blower, air conditioner or air cleaner.
3. The average concentration of the targeted gas in a room can be obtained by detecting at several locations of the room and then averaging the data.
4. Don’t contaminate or block the detection window, otherwise, the sensitivity of the sensor may deviate.

Carbon dioxide is a colorless, odorless, faintly acidic-tasting, non-flammable gas. In low quantities carbon dioxide is harmless. In moderate levels, people can start to experience mild effects of drowsiness, headaches and sleepiness. At high levels, carbon dioxide can be extremely harmful and is life-threatening. Therefore, it is essential to monitor levels of CO2 at all times, especially in industries that actively use it for their applications such as breweries, restaurants and laboratories, other than these areas we also spend a great deal of time indoors.
On average we spend more than 70% of our time indoors home, offices and other confined environments. If the air quality indoors (IAQ) is poor, this can lead to discomfort and bad health. This can be more damaging to children, those with respiratory conditions or heart diseases as well as the elderly.
The CO2000 Carbon dioxide data logger can actively measure and log CO2, temperature and humidity levels within a confined space indoors. Logging the data to show if there are irregularities during any time of the day and sound of an alarm when Carbon dioxide levels reach or surpass a certain level.
Suitable for: hot water pipes, hot engine parts, cooking surfaces, hot tubes insulation, electrical connection, ballasts in electric lights, electric motors, bearings, wine coolers hot asphalt, swimming pools, fish tanks, hot & cold food products, heating air conditioning, etc.
High quality with one year warranty.
