Background：

Hydrogen sulfide gas is a colorless and highly toxic acid gas, and a low concentration of hydrogen sulfide has the smell of rotten eggs. It can damage people's sense of smell, and high concentrations of hydrogen sulfide can cause immediate death. Therefore, the detection of hydrogen sulfide by smell is fatal, and the detection of hydrogen sulfide gas mainly requires special equipment. Portable hydrogen sulfide detector is the primary detection method when leakage occurs in sulfur-containing oil and gas wells.

Features：

Handheld Hydrogen Sulfide Detector: carry it with the field operators. There are two alarm values. When the concentration reaches the highest, the instrument will intermittently sound and light alarm. When the concentration reaches the second alarm value, the instrument continuously sends out sound and light alarms, and the concentration data is displayed on the LCD digital display. With night lighting function. When its headset can pass the alarm value under strong noise conditions, the instrument will emit a series of audible and visual alarms. And display the hydrogen sulfide concentration on the LCD digital screen. It has the characteristics of small size, light weight, fast response speed and high sensitivity.

Detection method requirements：

• ●Open the power supply, check the power supply voltage, you must ensure that the voltage of the instrument is sufficient
• ●To ensure accuracy, we need to calibrate the zero point once a month. And calibrate the probe regularly.
• ●If the portable hydrogen sulfide detector is in a place with clean air, the digital indication is not "000". Adjust the zero potentiometer so that the indication should be "000". If we find the device is substandard or the numbers jump a lot, we should replace the sensor.
