Tips: Troubleshooting Fixed Chlorine (Cl2) Gas Detectors

Unable to Turn on or Have No Display: First, make sure the gas leak detector power connection is normal, then check the power switch and power cord. If the problem persists, the battery may need to be replaced or the supply voltage checked.
Inaccurate Measurements: If you suspect inaccurate measurements, you can first perform a calibration to ensure the gas detector is in the correct working order. Also, check to see if the gas detector sensor needs replacing or cleaning to make sure it's working properly.
Alarm Unresponsive: If the gas leak detector is not responding to gas alarms, check that the alarm is in silent mode and make sure the alarm is set correctly. Also, check to see if the gas alarm is damaged or needs to be replaced.
Unable to Connect to the Gas Monitor System: If the gas meter cannot connect to the monitoring system, check whether the communication lines and interfaces are normal. Make sure the connection lines are not disconnected or damaged.
Continuous Alarm or False Positive Alarm: If the gas monitor emits a continuous gas alarm or false positive alarm, check whether the Cl2 concentration in the environment is really above the alarm threshold. Also, check the status and performance of the gas sensor, which may need to be calibrated or replaced.

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.
