Frequently Asked Questions - HC-RTHCO2 Mach Power
How is the CO2 sensor of the HC-RTHCO2 calibrated?
To calibrate the sensor, place the device in an area with fresh air (400 ppm CO2) and hold down the calibration button for 3 seconds. The process takes about 2 minutes and should be performed outdoors or in a well-ventilated environment.
What does the CO2 value in ppm mean?
ppm stands for parts per million. It indicates how many CO2 molecules there are per million air molecules. A level of 400 ppm is typical outdoors, while more than 1000 ppm may indicate poor indoor ventilation.
How often should I clean the device?
It is recommended to clean the exterior with a soft, dry cloth at least once a month. Avoid using harsh chemicals that could damage the display or sensors. Make sure the ventilation openings are not obstructed by dust.
How do I change the battery?
The battery is rechargeable and built-in. It does not need to be replaced frequently. If battery life decreases noticeably, open the back cover with a small screwdriver and disconnect the battery. Replace it with one of the same specification (3.7 V, 18650).
Can the device be used outdoors?
Yes, the allowed temperature range is 0 °C to 50 °C. However, avoid exposure to rain or extreme humidity, as the device is not waterproof. For outdoor use, protect it under a roof.
How are CO2 levels interpreted?
According to the ASHRAE standard, a level below 800 ppm is recommended for indoors. Between 800 and 1000 ppm indicates moderate ventilation, and above 1000 ppm it is recommended to ventilate. Exceeding 2000 ppm can cause drowsiness.
How do I set up the alarms?
Press the settings button to enter the menu. Select the alarm threshold (CO2 value) and choose whether you want sound and/or vibration. Confirm with the OK button. The alarm will activate when the level exceeds the threshold for 1 minute.
What maintenance does the NDIR sensor need?
The NDIR sensor has a long lifespan (more than 5 years). To maintain its accuracy, avoid exposing it to solvents or corrosive gases. Perform manual calibration every 6 months or after a drastic change in altitude.
How do I export the recorded data?
Connect the device to a computer using the USB-C cable. It will appear as a storage drive. The data is saved in a CSV file that you can import into Excel or analysis applications. Use the included software or a text viewer.
What is the lifespan of the sensor?
The expected lifespan of the NDIR sensor is approximately 5 to 7 years under normal use conditions. If readings become inaccurate or unstable, the sensor may need to be replaced. Refer to the manual for the procedure.
