What is over-range usage? What is the danger of over-range use?
Every time a customer asks for a gas detector, the salesperson will repeatedly emphasize the problem of the range. Why is this emphasized? Let us introduce the importance of it.
All types of toxic and harmful gas detectors have their own fixed detection range. Only when the measurement is completed within the measurement range can the instrument be accurately measured. If the measurement is exceeded for a long time beyond the measurement range, it may cause permanent damage to the sensor. For example, the oxygen detector range is 0-25% VOL, and if it is used in an environment with more than 25% VOL, it is possible to completely burn the sensor. The toxic gas detector can cause damage when used for a long time at a higher concentration. Therefore, if the instrument emits an over-limit signal during use, the instrument should be immediately evacuated from the gas source to ensure the safety of the sensor.
