Import Ar8500 Ammonia (Nh3) Gas Detector — Buy in wholesale FOB from Supplier in China

The AR8500 ammonia gas detector is a portable, electrochemical sensor-based instrument designed for continuous quantitative analysis of ammonia (NH3) concentrations in air. It delivers a measuring range of 0 to 100 ppm with a resolution of 0.1 ppm and a basic error margin of ±0.5 ppm, ensuring precise detection for industrial and environmental applications. The device features a response time and recovery time of under 120 seconds, with repeatability within ±1%, making it suitable for real-time monitoring in dynamic environments.

This detector incorporates an imported electrochemical sensor with a typical service life of 2 years, replaceable to maintain long-term reliability. The unit is powered by 3 x 1.5V AA batteries, providing approximately 100 hours of continuous operation with the backlight disabled. Its compact dimensions of 182 x 66 x 32 mm and LCD backlight display allow for easy handling and clear visibility of gas concentration, working state, and alarm status. Electrochemical NH3 sensors are a standard choice for such detectors due to their selectivity and sensitivity to ammonia in low-ppm ranges.

Common applications include ammonia detection in farms, animal husbandry, landfills, and frozen storage facilities, as well as ambient air monitoring, hazardous space entry checks, and leakage detection in storage tanks or pipelines. Industrial buyers such as metallurgical plants, power stations, and chemical manufacturers use this detector to comply with workplace safety standards. The dual-grade alarm system, with an audio output of up to 80 dB, ensures immediate alerts for threshold breaches, a critical feature for environments where ammonia exposure poses health risks.

Week Technology Ltd. is based in Shenzhen, Guangdong, China, operating from the 16th floor of Building #3, Zhongke Mansion. The company specializes in gas detection equipment, with a focus on electrochemical sensor-based analyzers for industrial and environmental applications. Its product portfolio includes portable and fixed gas detectors tailored for hazardous gas monitoring in sectors such as metallurgy, chemical manufacturing, and environmental protection.

The supplier’s profile indicates an imported tier classification with a harbor trust tier, signifying a baseline level of verification for international trade. While the response rate and average response hours are currently listed as zero, this reflects a lack of recent activity rather than a confirmed operational limitation. Buyers are advised to contact the supplier directly to confirm current responsiveness, technical support capabilities, and any additional certifications or compliance documentation for the AR8500 model.
