Hydrogen Detector- EST-10-Ⅱ-H2 Natural Diffusion Built-in Storage
The EST-10-Ⅱ-H2 hydrogen detector adopts a natural diffusion gas detection method and also offers an optional handheld sampling pump to meet a wider range of application environments. The sensitive element adopts advanced sensors, featuring high sensitivity and excellent repeatability. It is equipped with an LCD liquid crystal display screen, allowing for on-site online observation of the concentration value of the target gas. It features two-level alarm output. Once the preset alarm point is exceeded, it will immediately trigger an audible and visual alarm prompt. It has two calibration methods and can complete the calibration work without opening the cover.
The instrument is equipped with an internal storage chip that can store 100,000 pieces of data. The product will only be finally released from the factory after it complies with the relevant national standard GB_T 18204.2-2014 "Hygiene Inspection Methods for Public Places - Part 2: Chemical Pollutants".
Product features
It adopts superior sensor technology, featuring stable and reliable performance.
2. External power supply: DC5V, built-in rechargeable 3.7V lithium battery. It can be charged by connecting to an external power source.
3. The LCD screen can display various parameters, and it has an automatic calculation function for 5-minute and 15-minute average values.
5. Intelligent design, complete functions, zero adjustment, alarm setting and calibration are very convenient.
6. The shell is compact and lightweight, which can be placed in a pocket or bag, or hung on the body, making it convenient to carry.
7. Two-level sound and light alarm, with two high-brightness leds to alert users when an alarm occurs.
8. This instrument is equipped with data storage and export functions, facilitating users' data analysis.
