HRP-670 Tetrahydrothiophene Detector: Natural Gas Safety and Leakage Detection Solution
Product introduction
Tetrahydrothiophene (THT) is a substance commonly used to odorize natural gas. Because natural gas itself has almost no obvious smell, odorants such as THT are usually added to make the potential natural gas leakage easier to find. However, judging only by people’s sense of smell can not meet the needs of professional detection. Using professional THT detector can provide a more convenient and objective detection method for on-site detection.
HRP-670 tetrahydrothiophene detector is a portable gas detection equipment specially used for THT detection. The instrument adopts a pumping sampling system, which actively sucks gas into the equipment for detection. The staff can detect natural gas pipelines, valves, flanges, pipeline joints and other suspected leakage points.

Pumping sampling, suitable for on-site detection
An important feature of HRP-670 is the active pumping sampling method. Unlike waiting for gas to naturally diffuse into the detector, the instrument actively sucks ambient gas through the built-in sampling pump and sends the gas into the detection chamber for analysis.
This design is very suitable for professional on-site inspection. When workers need to check a specific location, they can put the sampling probe close to the detection point to carry out targeted detection on gas equipment. HRP-670 is suitable for routine natural gas pipeline inspection and abnormal gas equipment investigation.
Designed for natural gas applications
HRP-670 can be applied to a variety of natural gas and industrial gas scenarios, including natural gas pipeline inspection, urban gas transmission and distribution, gas pressure regulating station, gas equipment maintenance, natural gas odorizing agent detection and suspected gas leakage detection.
For gas companies and equipment maintenance teams, the portable detector can directly complete the detection on the spot, reduce the inconvenience in the detection process and improve the efficiency of daily inspection and maintenance.
Protective performance and long battery life
HRP-670 adopts built-in rechargeable lithium battery, and its working time is ≥10 hours, which is suitable for long-term on-site inspection and mobile detection.
The instrument has IP54 protection grade, and the explosion-proof mark is Ex ib IIC T4 Gb. At the same time, the equipment supports the working temperature range of -30 C ~ 70 C, which can meet the field detection requirements in various industrial and outdoor environments.
Portable design
HRP-670 has a size of 245 × 135 × 45 mm and a net weight of about 775 g, which is specially designed for on-site portable detection. The compact structure is convenient for gas technicians, pipeline inspection personnel, equipment maintenance personnel and industrial safety management personnel to carry and use.
Summary
HRP-670 tetrahydrothiophene detector provides a practical solution for THT detection in the field of natural gas and industrial gas. With pumping sampling, adjustable alarm point, long battery life, explosion-proof design, IP54 protection and portable structure, HRP-670 is suitable for daily gas inspection, suspected leak detection and gas safety management.
