Intelligent hot bulb anemometer

Etiedt Yitai Jingke Digital Anemometer

1、 Introduction:

ZRQF-F30JIntelligent hot bulb anemometerA metal wire heated by an electric current is cooled by flowing air, and the heat dissipation rate is linearly related to the square root of the wind speed. Then, it is linearized through electronic circuits (for easy calibration and reading) to make a hot wire anemometer, which can directly measure the temperature of the hot wire itself while measuring the wind speed. The hot wire anemometer has high sensitivity at low wind speeds and is an important tool for clean environment engineering, HVAC engineering, atmospheric turbulence, and agricultural meteorological measurement.

four ️⃣. Precautions for use

4.1 In wind speed measurement, it is necessary to align the sensitive components on the probe with the direction of incoming wind.4.2 If the instrument malfunctions due to manufacturing defects within one year from the date of leaving the factory,The manufacturer is responsible for free replacement or repair of damaged parts（Excluding damage to sensitive components）.4.3 To ensure the accuracy of instrument measurement, users should annually obtain approval from the metrology departmentCalibration is performed on specialized equipment. If the local conditions are not met, our factory can also handle it on behalf of us.4.4 In the process of production and sales, if our factory encounters any issues with the type, packaging, specifications, etcChanges to the surface are subject to change without prior notice.5. Fault Symptoms and Handling Methods5.1 If the sensitive component - hot ball - is contaminated with dust and dirt,In shutdown stateRemove the probeCap, place the probe in anhydrous ethanol and gently swing to remove dirt. If necessary, use itUltrasonic cleaner, never use a brush to scrub or let other objects touch the hot ballLead wires to avoid damaging the hot ball or changing its position, which may affect the accuracy of the measurement.5.2 If there is no display on the screen after booting up, or if the power suddenly drops during use, it can be turned onBattery compartment cover, check if the contact spring has good battery contact.If none of the above measures can eliminate the fault, please send it to our factory for processing. Please do not self destructDisassemble the machine for handling, otherwise the consequences caused by this shall be borne by the user.
