Recording portable gas detector The EST-10-Ⅱ series recording gas detector is a high-precision and low-power intelligent handheld alarm that uses advanced electrochemical technology to detect the concentration of toxic and harmful gases in the target gas.Recording portable gas detector
EST-10-Ⅱ series is a natural diffusion gas detection method (optional hand-held external pump), the sensitive element adopts advanced electrochemical toxic gas sensor, with high sensitivity and excellent repeatability; with an LCD The LCD screen can observe the target gas concentration value on-site; it has two-level alarm output, and the sound and light alarm signal is activated immediately when the preset alarm point is exceeded; it has two correction methods of soft and hard, and the calibration can be completed without opening the cover; There is a memory chip inside, which can store 100,000 pieces of data.
This instrument has the following characteristics:
1. Advanced electrochemical sensor, stable and reliable performance;
2. External power supply DC5V, built-in rechargeable 3.7V lithium battery, can be charged when connected to an external power supply;
3. The LCD screen can display various parameters, and the data can be viewed at a glance.
5. Intelligent design, complete functions, zero adjustment, alarm setting and calibration are very convenient;
6. The shell is small and light, which can be placed in a pocket or bag, or hung on the body, which is convenient to carry;
7. Two-level sound and light alarm, 2 bright LEDs remind users to pay attention when alarming;
8. This instrument has a data storage function, which is convenient for users to analyze data and monitor environmental gases for a long time.
