Description
Overview
GAO Tek Portable Multi Gas Detector it can be used in rapid detection of a variety of gas concentration and measurement of environmental temperature and humidity. If the measurement exceeds the limit value, the alarm will emit sound & light vibration as an alarm. It adopted advanced electronic circuit design, mature kernel algorithm processing, unique external appearance design, had achieved a number of patents about the software works, and external appearance.
Features
- Detects multiple gases, providing comprehensive safety monitoring
- Designed for easy carrying and on-the-go use
- Utilises advanced sensors for accurate gas measurement
- Intuitive interface for simple operation
- Provides continuous monitoring and instant gas concentration readings
- Stores historical data for analysis and reporting
- Allows users to set sensitivity levels for different applications
- Built to withstand tough environments and conditions
