Co2 Leak Detector-The Range Of The Sound And Light Alarm Is Selectable
The EST-10-II series carbon dioxide gas detector is a high-precision and low-power intelligent handheld alarm that uses advanced electrochemical technology to detect the concentration of toxic gases in the air.
The EST-10-Ⅱ series carbon dioxide gas detector adopts a natural diffusion gas detection method (a handheld external pump can be optionally equipped). The sensitive component uses an advanced electrochemical toxic gas sensor, which features 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, the audible and visual alarm signal will be immediately activated. It has both soft and hard calibration methods, and the calibration work can be completed without opening the cover. The instrument is equipped with a storage chip inside, capable of storing 100,000 pieces of data. It can be connected to a computer via USB to export data tables.
Product features
1. Advanced electrochemical sensors with 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, making the data clear at a glance.
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 a data storage function, which facilitates users to conduct data analysis and monitor environmental gases for a long time.
