Principle
The detector adopts the pump-suction Sampling method, and the environment gas is sucked into the air chamber inside the instrument through a built-in powerful air pump. The instrument has an imported Electrochemical sensor (for detecting CO, H2S, O2) and a heat conduction Sensor (for detecting EX combustible gases). The Sensor converts the gas concentration signal into an electrical signal, and the ultra-low power 32-bit microprocessor performs data processing and temperature compensation. Finally, the gas concentration value, temperature and humidity information are displayed in real time on the industrial-grade color screen, and data can be stored according to the settings.
Applications
Suitable for four-in-one gas concentration detection in various industrial environments and special environments
Standards
GB3836.1-2010、GB3836.4-2010
Steps
1. Boot Check: Ensure that the instrument has sufficient power and the Sensor and Filter are in normal condition.
2. Mode settings: Set the required detection mode, storage mode, display mode and air pump mode through the menu.
3. Start testing: Start the instrument, start the air pump, and suck the gas to be tested for testing.
4. Read the data: view the gas concentration (unit can be switched) and temperature and humidity information in real time on the color screen.
5. Data management: Historical data records can be viewed on the screen, or data can be transferred through the data export function.
6.Calibrate and maintain: Automatic calibration or target point calibration according to prompts or plans.
7. Shut down and charge: shut down after use, and charge the built-in polymer battery.
Notice
• Do not use under conditions exceeding the specified working environment (temperature -30~ 60 ℃, humidity 0~ 95% RH without condensation, air pressure -30Kpa~ 200Kpa).
• The instrument has the explosion-proof mark Ex ia II C T4 Ga, but still needs to be used in the specified explosion-proof environment.
• Note that the Protection Rating is IP65, which can be dustproof and water-proof, but non-diving equipment, do not immerse in liquids.
• The built-in battery is a rechargeable polymer battery, please use the matching charger and pay attention to the overcharge protection function.
• The instrument is equipped with a dust Filter, which needs to be checked and replaced regularly when used in harsh environments to ensure the accuracy of detection.
When calibrating, make sure to use standard gas and operate in a safe environment.
• Avoid strong static or magnetic field interference in the instrument.
• When not in use for a long time, please charge it regularly to keep the battery active.
