Gas detectors need to be calibrated and tested regularly
Gas detector is a relative comparison of the method of running the measurement of the first zero gas and a standard concentration of gas to run the calibration of the gas detector, toxic and hazardous gas detector is also the same as other analytical detection of gas detectors. Get the normative curve stored in the gas detector, measurement, the gas detector will be measured gas concentration of electrical signals generated with the standard concentration of electrical signals run comparisons, calculations to get the accurate value of the gas concentration.
Therefore, at any time on the gas detector run zero, regular calibration of the gas detector run are to ensure that the gas detector measurement is accurate and indispensable work. It should be noted that many gas detectors are replaceable sensors, but this does not mean that a detector can be used at any time with a different detector probe. Whenever a probe is replaced, the gas detector must be recalibrated in addition to the sensor activation time. In addition, it is recommended that all types of gas detectors be run with a standard gas response test before use to ensure that the gas detector is actually maintained.
Gas detector malfunction simple processing methods
1, if the gas detection and alarm instruments if the product for the use of the situation can not be opened normally, please check whether the battery power is sufficient. If the battery is not charged, please charge the battery according to the instructions on the instructions. If in the process of use found that the instrument can not work properly, the power is not a problem, the principle of the measured gas, wait 3-5 minutes, waiting for the instrument value to return. If the problem can't be solved by yourself, then re-labelling gas (or mailing Australia new instrument Beijing headquarters for labelling gas). If the problem can not be solved, please contact our customer service staff to send Australia's new instrument headquarters in Beijing for overhaul.
2,If it is on-line testing instrument. Check whether the line is smooth. Use the observation method Use the sense of sight, smell and touch. At some times, the damaged components will be discoloured, blistered or have burnt spots; burnt devices will produce some special smells; short-circuited chips will be hot; with the naked eye can also be observed at the virtual welding or desoldering. If the problem can not be solved, please contact the customer service staff of Australia New Instruments Beijing headquarter and mail it back to us for overhaul.
