Portable Ozone Detector -EST-10- II -O3
1.Product introduction
EST-10-Ⅱ series recording gas detector is an intelligent hand-held alarm with high precision and low power consumption, which uses advanced electrochemical technology to detect the concentration of toxic gases in the air.
EST-10-ⅱ series is a natural diffusion gas detection method (hand-held external pump can be selected), and the sensitive element adopts advanced electrochemical toxic gas sensor, which has high sensitivity and excellent repeatability; With an LCD screen, the concentration value of target gas can be observed online on site; With two-stage alarm output, the acousto-optic alarm signal will be started immediately when it exceeds the preset alarm point; With soft/hard calibration methods, calibration can be completed without opening the cover; There is a memory chip inside the instrument, which can store 100,000 pieces of data. USB is connected to the computer to export data tables.
2.Product highlights
1. Advanced electrochemical sensor with stable and reliable performance;
2. external power supply DC5V, built-in rechargeable 3.7V lithium battery, connected to the external power supply can be charged;
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, can be placed in a pocket or bag, and can also be hung on the body, which is convenient to carry;
7. Two-stage acousto-optic alarm, with two highlighted LEDs to remind users of the alarm;
8. This instrument has data storage function, which is convenient for users to analyze data and monitor ambient gas for a long time.
