The Model 351 is Europe’s smarter brother to the Model 341. The 351 has twice as many ranges that will measure flows down to 0.6 liters per second but will also go up to 350 liters per second to test houses by adding the optional frame package. Over 30 years of airtightness technology and design expertise have gone into making this the most flexible but also the most reasonably priced DucTester for residential and small commercial duct tests at 80, 160 and 250 Pascals.
Super lightweight, easy operation, great quick guides make this the best choice for testing European ducts. Runs on any voltage from 100 to 280 Volts or for 3 hours on an optional 48 Volt Lithium Ion battery pack that weighs 3 kg.
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.
