HRP530 Mini Handheld Telemetering Gas Detector
Product description
HIREP HRP530 mini handheld telemetering gas detector is a compact and high-precision laser methane detector, which is specially designed for fast and non-contact detection of CH4 gas leakage. The instrument adopts tunable diode laser absorption spectroscopy (TDLAS) technology, which can remotely detect methane concentration without direct contact with the leaked gas source.
The detection range of HRP530 is 0–100,000 ppm m, the resolution is 1 ppm·m, and the fastest response time is 0.1 second, which can quickly and reliably identify gas leakage. The equipment provides optional detection distances of 15m, 30m and 60m, which is suitable for detecting pipelines, storage facilities, industrial equipment and other potentially dangerous areas from a safe distance.
The mini handheld design makes the whole machine weigh only 230 grams, and the durable industrial aluminum alloy shell combined with IP65 protection level can meet the use requirements in harsh working environment. Through Bluetooth connection and dedicated detection APP, data transmission and monitoring can be carried out conveniently. When abnormal methane concentration is detected, sound and vibration alarm can remind the operator in time.
principle of operation
HRP530 adopts TDLAS (tunable diode laser absorption spectroscopy) technology for remote methane detection.
The instrument emits infrared laser to the target area. When the laser passes through an environment containing methane, CH4 molecules will absorb the laser with a specific wavelength. The detector calculates the methane concentration in the optical path by analyzing the degree of laser absorption.
This laser detection technology enables HRP530 to realize remote and non-contact methane leakage detection, which helps operators to check inaccessible or potentially dangerous areas without directly approaching the suspected leakage point.
Application industry
HRP530 mini handheld telemetry gas detector is suitable for a wide range of industrial gas safety applications, including:
- Natural gas and gas transmission and distribution-pipeline leakage detection and gas facilities maintenance
- Petroleum and natural gas industry-methane leakage detection around production and storage facilities
- Petrochemical industry-monitoring of pipelines, valves, storage tanks and process equipment
- Gas filling station-natural gas equipment and pipeline inspection
