3、 Product Features
1. Adopting imported wide temperature OLED display screen, the human-machine interface with good Chinese menu and vivid graphics eliminates the need for adjustment comparison
Difficulty with temperature, it can work in ultra-low temperature environments.
2. Flow control adopts high-precision imported sensors, with good flow stability, high sampling accuracy, and automatic detection and sampling
Flow rate, automatic control of constant current sampling, compensating for flow fluctuations caused by voltage and resistance changes.
3. Automatically record the cumulative flow rate and time during the sampling process, and convert the standard volume based on air pressure and temperature.
Real time clock, with multiple sampling methods such as timed sampling, interval sampling, multiple sampling, and cyclic sampling.
4. Equipped with a rechargeable battery for storing data during AC power outages and automatically restoring sampling and deducting data during AC incoming calls
The power outage time during the sampling process can be checked by users.
5. Adopting imported fans with high load capacity and wide flow setting range, it can meet the requirements of high flow sampling. Long term continuous work
High stability, low noise, trouble free operation time greater than 20000 hours, long service life, able to operate at (-30-50) ℃
Working in the environment.
6. Automatically save the last user set parameters, and use them automatically the next time the device is turned on, achieving one click sampling. Can store multiple groups
Data, with a retention period of 10 years, convenient for users to query.
7. Overload automatic protection: During the sampling process, if the sampling flow rate is less than or greater than the set sampling flow rate, the instrument will automatically stop
Machine protection, power outage protection function: During the sampling process, if there is a power outage, the sampling data can be automatically saved, and sampling can continue after a power call.
8. Users can calibrate the instrument through a waterproof keyboard, and maintenance requires password access to ensure the security of instrument data
It can easily be modified incorrectly and provides the function of restoring factory settings.
9. The unique rainproof design is suitable for any environment, and the flip structure can be folded for easy transportation.
10. The whole machine adopts spray paint shell structure, anti-corrosion, anti-aging, suitable for long-term continuous use in the field.
11. Adopting a pull-out PUF cylinder sleeve, it is easy to operate and install.
