Tips: Gas detector troubleshooting

The number cannot be displayed correctly
If the gas detector has been used for a long time, or it has not been calibrated for a long time, there will be a problem of incorrect readings. We all know that the gas detector is mainly detected by the internal sensor. The sensor has a certain life. When used for a certain number of times, the sensitivity of the sensor decreases, which affects the detection result. In addition, if the calibration is not carried out for a long time, the test results will also be affected.
The gas detector cannot inhale
This type of problem mainly occurs on pump-aspirated gas detectors. A small suction pump inside the detector is used to inhale gas for detection. Once the suction pump is damaged or other failures, the gas detector will not be able to inhale. This problem is easy to deal with, and a new suction pump can be replaced.
The gas detector fails
Such faults are prone to occur in special working environments, such as the presence of a lot of dust and oil in the detection environment, which will contaminate the gas detector and lead to failure. In such an environment, the gas detector needs to be cleaned.

How to Calibrate a Fixed Gas Detector?

This video introduces the zero calibration process of a fixed gas detector. When the air is clean, press the menu first, then press the "+" key to enter F04, then press the OK key, and then press the BACK key. The detected data will become zero. Prepare the standard gas, we use isobutane for calibration.

Step 1: Press the menu, then press the "+" key to enter F07, change the data to the same as the standard gas value, and press OK.
Step 2: Press the menu, then press the "+" key to enter F08, now you will see it shows 0, change it to 1, and then press the OK key to return.
Step 3: Connect the sensor to the standard gas, the gas flow rate is 500mL/min, and press the OK key after the data stabilizes.

Portable Oxygen Gas Detector with PC Interface

The Smart Handheld Gas Detector from ATO is designed to detect oxygen in a range from 0% to 30%. In this video, ATO will show you that the detector uses a micro sampling pump to draw in the measured gas with the max flow rate up to 1L/min. The LED display provides simultaneous pickup of gas variety, density units, the maximum value, local time and atmospheric temperature, etc.

Existing reviews of Fixed Sulfur Dioxide (SO2) Gas Detector, 0 to 20/50/100 ppm

Give me some recommendations

I was tasked with identifying equipment necessary to set up 3-4 ground level sulfur dioxide monitoring stations at my facility. We manufacture zinc and sulfur dioxide generated in the process is converted to sulfuric acid. Occasionally, we have small leaks so early detection is needed. Do you have any recommendations?

ATO Responded

According to your description, we recommend GD300-SO2, which has a range of 0-20ppm, 0-50ppm, and 0-100ppm, and can detect the leakage concentration of SO2 in the air in real time 24 hours a day.
