1. Basic performances of ZRQF intelligent hot-bulb anemometer
1) Basic measuring range: 0 - 30 M/S
2) Basic accuracy: ± (true value ´3%) ± 5 least significant digits
3) Additional error: in case the deviation of the probe direction is within ±15°, its additional error shall not be greater than ±5% of the true wind speed.
4) The response time of probe shall not be greater than 3 seconds.
5) After users input the sectional area of the detected duct, the wind volume ( unit M/S) can be calculated, displayed and printed out;
6) Two types of measurement modes i.e. measure-to-display and timing average for selection;
7) The measurement data can be automatically memorized;
8) The printer can be connected for the print out of the measured time and data;
9) The constant current working mode is adopted, the zero self-compensating function is provided with;
10) ZRQF series intelligent hot-bulb anemometer is provided with the standardized and the simplified keyboards, which makes its operation more convenient. Its ZRQF-J type is more suitable for popular use, its ZRQF-W type with the measuring range of 0.5 M/S is more suitable for gentle breeze measurement.
2. The measuring results can be printed out or read out.
1) The meter is provided with the memory area which can storage approximately 300 measuring data. The measuring results can be memorized and storaged. After the printer is connected, the memorized measuring date and measuring results can be printed out.
2) If the users do not use printer, the memorized measuring results can also be displayed on the display screen.
3. Power supply
1) For users’ convenience, the meter is provided with the built-in rechargeable battery. When the internal battery is of no power, the auxiliary power converter can be used for current supply, and can also be used for the internal battery charging.
2) The meter is provided with the undercurrent indication.
3) The meter can also use AC power after plug-in of power converter.
