HRP-670 Tetrahydrothiophene Detector: Portable THT Gas Detection Solution
Product introduction
HRP-670 tetrahydrothiophene detector is a professional portable gas detector, which is specially used to detect tetrahydrothiophene (THT). The instrument adopts a pumping sampling system, and actively sucks gas into the instrument for detection, which can realize fast and reliable THT concentration measurement.
Tetrahydrothiophene (THT) is usually used as a natural gas odorizing agent. HRP-670 is suitable for natural gas pipeline inspection, gas transmission and distribution system, pressure regulating station, industrial gas facilities and suspected leakage point detection.
Principle of operation
HRP-670 actively sucks the surrounding gas into the detection cavity through the built-in sampling pump, and the sensor detects the THT concentration in the gas. After signal processing, the detection result is displayed on the instrument.
When the detected concentration reaches the preset alarm value, the instrument will give an alarm to remind the staff to carry out safety inspection in time.
Detection process:
Gas sampling → sensor detection → signal processing → concentration display → overrun alarm.
Application area
HRP-670 can be applied to a variety of gas safety detection scenarios, including:
- Inspection of natural gas pipeline
- Urban gas transmission and distribution
- Gas pressure regulating station
- Detection of natural gas odorizing agent
- Gas equipment maintenance
- Suspected gas leakage detection
- Oil and gas facilities
- Industrial gas system
