Tips: Installation of Fixed Hydrogen Sulfide (H2S) Detector

Fixed hydrogen sulfide (H2S) detector shall be installed in the areas which are easy to release and gather the hydrogen sulfide gas, such as the drilling site, downhole operation site, gathering station, natural gas evolution field, water treatment station and refinery area.

The mounting site of fixed-type H2S detector should be determined by on-site facilities, processes, and the diffusion and gathering of hydrogen sulfide gas.

The fixed hydrogen sulfide (H2S) detector should be installed below the release source, and it shall be within 2m outside and within 1m inside. Moreover, the detector is better to be installed at 0.5-0.6m away from the gas release source. The installation height shall be 0.3-0.6m higher than the ground or floor. If the detector is installed lower, it’s easy to be affected by the rain drops, which may damage the detector.

If possible, please select the gas detectors with concentration display and acousto-optic alarm. The operators can observe the existence of hydrogen sulfide gas on site without returning to the duty room to see the alarm controller. It is finally better to protect them.

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 Hydrogen Sulfide (H2S) Gas Detector, 0 to 50/100/200 ppm

Gas detectors

For several years I have been using Hydrogen Sulfide (H2S) Gas Detectors and Fixed Ammonia (NH3) Gas Detectors to monitor odors around an industrial zone. They work perfectly - no problems. The sensors work continuously outdoors, in various weather conditions (summer/winter). The sensors have little drift. Contact with the company's support is also impeccable.
