A carbon dioxide monitor is an instrument that measures the concentration of carbon dioxide. The CO2 monitor can measure carbon dioxide concentrations in the range of 0-2000 PPM with a resolution of 1 PPM and an accuracy of ±50 ppm. The CO2 meter can record up to 30,000 sets of data.
Use cautions:
1, the instrument charging time is 6-7 hours, do not exceed 8 hours.
2, the sensor and the circuit should pay attention to the metal impurity of the waterproof box.
3, do not charge in the boot check state.
4. The instrument is not used for a long time. It needs to be stored in a dry, dust-free environment. It should be charged before it is used again. It should be checked after 10 minutes.
5. The instrument's inspection result is to quantitatively display the concentration of carbon dioxide in the air within the margin of error. It should not be used as a statutory inspection result in accordance with relevant regulations.
Common faults and maintenance:
1, can not boot or automatically shut down. The reason is that the voltage is insufficient and the processing method is charging.
2, the reading is low. One-zero drift causes the treatment method is clean air calibration; Reason two range drift, processing method to modify the calibration coefficient.
3, the reading is high. One-zero drift causes the treatment method is clean air calibration; Reason two range drift, processing method to modify the calibration coefficient.
We devote ourselves to protect the environment,so we passed FSC factory inspection.The certificate is really very hard to get, it controls strict to what paper material we use and ensure we do not use those rare tree, also protect human rights.
All the materials we used is eco-friendly. Our leatherette paper are imported from Netherlands(The one LEUCHTTURM is using now) ,PU are from Alpha( The best PU factory in China) and paper are from APP / UPM etc.(The best paper factory in China).
