Description
Overview
GAOTek Gas Test Instrument is a specialized device designed for detecting and analyzing nitrogen gas (N2) leaks. It offers a fast response time of 10 seconds and is capable of measuring nitrogen gas concentrations in the range of 0 to 100 % volume. The instrument is primarily used for leak detection purposes, ensuring the integrity and safety of nitrogen gas systems. It is an essential tool for industries such as manufacturing, aerospace, electronics, and HVAC that rely on nitrogen gas for various applications.
Features
- It can detect 1 to 5 kinds of gases at the same time, and the unit can be switched
- The sampling distance is larger than 32.81 ft (10 m), and the special gas circuit design can be directly detected
- Using 5500 mA large-capacity rechargeable polymer battery
Multiple alarm mode settings - Low alarm, high alarm, interval alarm, weighted average alarm
- Mistaken operation recognition function
- Zero-point automatic tracking, long-term use will not be affected by zero-point drift
- Multi-level calibration of target points to ensure linearity and accuracy of measurement Chinese and English interface can be selected
