It uses 2.4 inch high definition color screen to display data in real time, built-in well-known brand Sensor, detection principle includes electrochemistry, infrared, etc., can detect more than 1000 kinds of gas, suitable for pipeline, confined space, atmospheric environment gas concentration detection, leakage monitoring or high purity single Gas Analysis.
Features
1. With waterproof splash, dustproof, explosion-proof, shock-proof characteristics, using intrinsically safe circuit design, anti-static and electromagnetic interference, Protection Rating IP65, built-in water vapor and dust Filter.
2. It can directly detect gases with negative or positive pressure of 0.05 MPa.
3.2.4-Inch high definition color screen displays real-time concentration, alarm, time, Humidity, storage, communication, power and other information, and the menu adopts simulation icons.
4. Large capacity Data storage, standard 100,000, support real-time, timing or only store alarm data, data can be viewed locally, deleted or uploaded to the computer through USB analysis.
5. USB charging interface, compatible with computer, power bank and mobile phone charger, with overcharge, overdischarge, overvoltage, short circuit, overheating protection, 5-level power display, support hot swapping, charging can work normally.
4500 mA large-capacity rechargeable polymer battery is used to support long-term continuous operation.
7. Equipped with sound and light, vibration, vision, under-voltage and fault alarms, three-dimensional display of alarm status, alarm value and mode (low report, high report, interval report, weighted average report) can be set.
8. Optional High Accuracy Humidity measurement function, and temperature compensation for Sensor, Temperature range -40 ℃~ 70 ℃, can detect gas up to 400 ℃ (higher temperature can be customized).
9. It can simultaneously detect 1-4 kinds of gases, and the unit can be selected from ppm, mg/m ³, etc., and supports three display modes to switch.
10. Chinese and English interface is optional, default Chinese, with data recovery, zero point automatic tracking, target point three-level calibrating, concentration calibrating misoperation identification and blocking, real-time or timing detection, calibrating and maintenance log recording, Sensor life and next calibrating time reminder and other functions.
Principle
The detection and alarm instrument adopts electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photoion and other principles of gas Sensor for detection. Through professional circuit design and mature core algorithm processing, the signal collected by the Sensor is analyzed to achieve accurate measurement of gas concentration, temperature Humidity compensation and excessive alarm.
Applications
Chemical, Petroleum, Environmental Protection Flue Gas Analysis, Pipeline, Boiler Gas Analysis, Air Treatment and other occasions that need to detect gas concentration
