Description
Overview
GAOTek Portable Ammonia Measuring Gas Leak Detector is a new type of detector for detecting gas leakage from the gas pipelines, gas valve, and other possible places. With imported high quality semi-conductor sensor and embedded microcontroller, it has very high sensitivity, excellent man-machine operation interface and various adaptive ability. The housing of the detector is made of high strength engineering plastics and compound anti-slip rubber. It is waterproof, dustproof, and with good handle.
Features
- Calibration and Auto-Zeroing: The detector may have calibration features and auto-zeroing functions to maintain accurate measurements over time
- Battery or Power Options: Portable ammonia detectors typically use replaceable batteries or have rechargeable battery options for convenient operation in the field
- Portability: The device is designed to be lightweight, compact, and easy to carry, allowing for on-site gas detection tasks
- Environmental Compatibility: Portable ammonia detectors are often designed to operate in various environmental conditions
- Robust Construction: The detectors are built with durable materials to withstand harsh environments and ensure long-lasting performance
- Compliance: Reliable portable ammonia detectors should meet relevant safety standards and certifications to ensure their accuracy and reliability
