You will be proud to own the very best residential DucTester made. Retrotec’s combined experience of two previous models gives you dozens of exclusive features.
We used our 30 years of airflow testing experience with customer feedback from our previous DucTesters to create the all-new 341 DucTester.
The new fan offers a continuous range from 10 CFM to 750 CFM with a wide coverage on each range. Flow can be measure down to a mind-blowing 0.36 CFM with optional ranges. We have injection molded the inlet nozzle, flow sensors and even the screens to achieve unheard of accuracy and stability along with a sturdy structure. Two rare-earth magnets hold and self-align the quick change range plate.
You will look professional when you walk in with the DM32 over your shoulder in a smart case that contains everything you need to test ducts. Your future needs will be taken care of since a wide range of accessories is starting to be developed that will let you use this new DucTester in a variety of roles, from testing small houses, building components, even powered flow hoods.
At only 7.8 lb (3.5 kg) this fan can be easily carried or held in one hand.
Switch ranges in seconds with snap-in range plugs and a magnetically attached end plate.
Match the colored tubes to the ports even when pressurizing where you normally need to run an extra tube but not with Retrotec where the gauge figures it all out. You’re always hooked up correctly, nothing to remember; you cannot make a mistake.
High-capacity batteries last 8 hours. Recharge them anywhere - even in your car or from your laptop. Save hundreds of dollars a year over throwing away batteries!
DM32 smart gauge will display results in any units – no calculations needed!
Retrotec DucTesters all come packed in one case, ready to test. This case has plenty of room for the fan, gauge, flex duct and all your tools. Stiff lid acts as a gauge stand and the rubberized base protects from water and mud.
With large soft knobs and custom molded handles.Parts are numbered for easy learning and reduced set up time.
Graphics of ranges and fans are quickly recognizable, while the results are large and easy to see, eliminating error. Your settings all come back when you restart your gauge.
10 different ranges allow you to choose the perfect setting for any test. Avoid changing ranges mid-test or having to pay extra for the ranges you’ll need.
We built the world’s first automated backpressure compensated flow chamber to improve accuracy under all conditions.
Great software for controlling your gauge remotely from a computer or a smartphone, performing auto and semi-auto tests, updating gauge software, and more – all included.
Blower door testing software for automated fan operation, data collection, and report generation.
In compliance with standards: ASTM E-779-10, ATTMA TSL1 and TSL2, CGSB 149.10, EN 13829 variants, USACE
Easy to use software developed by Retrotec to allow users to automatically generate professional reports that display test results with potential energy savings. Test details and contact information are easily entered into a spreadsheet with dropdowns and then display on the report printout. This is for use with the DucTester 200 or 300 series. For Microsoft Excel 2010 and newer.

All the software you will need to use your computer with the DM32.
Software to configure parameters on the DM32 family of digital manometers, provided as part of the DM32 Software Suite. The DM32 Configurator software updates parameters on gauges including Network settings, and is used to update the onboard software on the gauge (firmware) when the manufacturer releases new features.
Software to record two channels of pressure readings to a spreadsheet file in real time, for use with the DM32 or DM-2 digital gauge.
Software to remotely control and reflect the state of a real gauge connected to a computer, or to generate a simulated gauge on the computer which mimics the operation of a DM32 family gauge.
