Mini wind tunnel - Calibrator for air flow velocity

Product catalog summary

Overview: The document provides details on the precise calibration of air velocity using a mini wind tunnel and the creation of ISO calibration certificates. It highlights the capabilities and specifications of the Testo mini wind tunnel, which is used for testing and calibrating flow velocity probes and measuring instruments.

Specifications:

Three adjustable velocities: 2.5 m/s, 5 m/s, and 10 m/s.
Adjustable to PTB norm when used with the certified reference instrument Testo 400.
Accuracy: ±1% of the measurement value with a minimum deviation of ±0.1 m/s, plus calibration inaccuracy of the reference instrument's certificate.
Length: 610 mm; Interior diameter of measurement tunnel: approx. 100 mm.
Range of application: +10 to +40 °C.
Power supply: 230 V/50 Hz or 110 V, switchable, with built-in IEC socket.
Warranty: 2 years.

Procedures: The mini wind tunnel allows for regular and reliable testing of flow velocity probes. When used with a certified Testo measuring instrument, it enables the creation of ISO calibration certificates.

Limitations: Not suitable for vane probes with a diameter of 100 mm.

Recommendations: For optimal results, use the mini wind tunnel in combination with the DAkkS-certified reference measuring instrument Testo 400 to ensure measurements are adjusted to the PTB norm.

Mini wind tunnel - Calibrator for air flow velocity-1

Mini wind tunnel Calibrator for air flow velocity Precise calibration of the air velocity ! L A Creation of own ISO calibration certificates \ 'f- Adjustable to PTB norm in combination with certified reference instrument testo 400 Using the Testo mini wind tunnel, you can regularly and reliably test the flow velocity probes and measuring instruments in your company. If you additionally use the wind tunnel in combination with a certified Testo measuring instrument, you can also create your own ISO certificates. With the DAkkS-certified reference measuring instrument testo 400, the measurement values are adjusted to the PTB All Testo flow velocity probes are testable and calibratale with the mini wind tunnel (with the exception of vane probes with a diameter of 100 mm). The accuracy of the wind tunnel is ±1 % of the measurement value (minimum deviation ±0.1 m/s) plus calibration inaccuracy of the certificate of the respective reference measuring instrument.
