Tips: Maintenance of nitrogen gas detector

Regularly calibrate, test and inspect the nitrogen gas detector. In general, the calibration frequency is once a year.
As the most important part of nitrogen gas detector, the sensor should avoid exposure to the gas generated by inorganic solvents or organic solvents as much as possible. Especially for electrochemical sensors used to detect toxic and harmful gases, the evaporation or contamination of the electrolyte will cause the signal of the sensor to drop and shorten the service life of the N₂ gas detector.
When installing the nitrogen gas detector, please do not put it close to the wall, and reserve enough space around it for daily maintenance and troubleshooting.
Ensure that the nitrogen gas detector is in a dry state to avoid affecting its detection accuracy and service life due to the humid environment.
The entire outside of the nitrogen gas detector needs to be kept clean. You can wipe the surface with a soft damp cloth. Do not use a damp cloth dripping with water to prevent water droplets from accidentally splashing into the N₂ gas detector.
Dust cover of the sensor is for protection. In order to prevent the dust cover from being blocked by dust and affecting the use of sensor, it should be cleaned regularly.

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.
