The HRP-B1000-B is a portable, single-component toxic gas detector, specifically designed for the detection of particular toxic and hazardous gases. Suitable for confined space operations and on-site detection, it provides rapid early warning of leaks of single toxic gases, ensuring safety. These detectors are widely used in high-risk locations such as chemical industrial parks, wastewater treatment plants, metallurgical plants, confined space operations, and equipment maintenance, effectively preventing toxic gas poisoning accidents.
For jobs that only need to protect against a single risk, single gas detector is the king of cost performance.
1.Low procurement cost: the price is usually much lower than that of four-in-one or multi-gas detectors, which is suitable for small and micro enterprises with limited budget or large-scale popularization and equipment.
2.Simple maintenance: the service life of the sensor is usually long (2-3 years), and the calibration process is simple, and only one gas is needed for calibration, which greatly reduces the subsequent consumables and manual maintenance costs.

Usb cable(Standard):
This Micro USB cable features thickened copper cores and high-density nylon braiding, offering excellent resistance to bending and abrasion for long-lasting durability.
Portable Calibrator Calibration Gas Cylinder(Optional):
The high-precision standard gas supply device designed by portable gas detector is used for periodic calibration, zero correction and range verification of sensors in the field or laboratory to ensure the accuracy and reliability of long-term operation data of testing equipment.
Calibration Hood(Standard):
The compact calibration cover designed by portable hand-held gas detector is used to quickly and accurately complete the zero calibration and range calibration of sensors on the equipment site. It is small, light and precise in structure, which ensures that the standard gas can cover the sensor probe efficiently and avoid the interference of ambient airflow. It is an indispensable professional accessory for daily maintenance and compliance testing.
Air Sampling Probe(Optional):
The high-precision and long-distance gas sampling extension tool designed by portable hand-held gas detector is used to safely and stably extend the probe into narrow space, high place, deep well, pipeline or dangerous area for remote gas detection, which greatly improves the operation safety and detection coverage.Typically used with sampling tubes.
Portable Hand-held Gas Detector Charger(Standard):
The high compatibility, safe and reliable charging solution designed by portable hand-held gas detector includes a standard two-pin plug power adapter and a USB-A to Micro-USB/Type-C data cable (matched according to the equipment interface), which ensures that the equipment can quickly recover power after field inspection, factory duty or emergency tasks, and ensures continuous and stable operation.
Extended Sampling Tube(Optional):
The portable hand-held or pumping gas detector is designed with a high flexibility and corrosion resistance to extend the sampling catheter, which is used to extend the gas inlet of the equipment to the detection points that are difficult to directly contact, such as the depth of the pipeline, the equipment interlayer, the high vent, the inside of the closed container, etc., so as to realize "remote accurate sampling" and greatly improve the detection coverage and operation safety.
Water Vapor and Dust Filter(Optional):
Blocks solid particles from entering the detector's gas path, preventing blockage and avoiding particle adhesion to the sensor surface, which could cause sensor poisoning, decreased sensitivity, slowed response, or even permanent failure. It also avoids physical interference from dust, ensuring the sensor only contacts the measured gas, thus guaranteeing measurement accuracy.
