RETROTEC DU374 Calibration Plate for DucTester with 300 Series Fan
The RETROTEC DU374 calibration plate allows for quick and reliable verification of the accuracy of the DucTester 300 Series fan-equipped systems. It is designed for field calibration checks and helps identify equipment, installation, or usage issues before they affect the results.
The plate is attached to the end of the flexible duct, and—using its built-in pressure tap—the flow rate is measured through an opening of known size. Comparing the results indicates whether the system is operating as expected and when a formal recalibration is recommended. RETROTEC recommends performing this test for about five minutes each month.
Main features
- Field calibration verification in about 5 minutes.
- An orifice of known size for comparing the measured flow rate.
- Integrated fitting for the blue pressure hose.
- It is mounted at the end of the flexible duct.
- Genuine RETROTEC accessory.
Common applications
- Monthly Accuracy Check of the DucTester

- Decision on the Need for Formal Recalibration
