Core Operation Tips for Gas Detectors
For better use of the instrument, please carefully read the instruction manual before use.
2. Before testing, the preheating time of this instrument should be reasonably controlled. For example, if there is a high demand for results when it has not been used for more than 2 hours, it is recommended to preheat for 15 minutes.
If the battery level is less than 40%, it is recommended to charge it for emergency use.
4. This instrument is equipped with a PTFE sampling tube. If there is a lot of dust, it is recommended to use a sampling tube with a dust filter inserted into the air inlet (left nozzle). Otherwise, it is not recommended to use a sampling tube with a filter; The air outlet can be connected to the trachea according to the situation.
5. After detecting toxic and harmful gases, it is necessary to enter the detection mode again in a clean environment for gas detection until the concentration values of various toxic and harmful gases return to 0ppm, and continue for more than 1 minute before shutting down and placing it in the instrument box.
6. The ideal working temperature for most sensors is 20 degrees Celsius, so when used in low-temperature environments, the sensor response will be slower than usual, especially for semiconductor sensors such as odor sensors, which require a long preheating time and a certain temperature to accurately detect.
7. In environments with high humidity (greater than 65% RH), sensor signals are usually biased.
