The Model 451 is simply a Model 441 with an adapter that fits to the front of the fan. Change the test direction by moving the 100 mm flex from the outlet to the inlet adapter which snaps on in one second. No clumsy flanges to disassemble.
Test to 250, 1000 or even 5000 Pa! Sufficient flow for almost every test. 600 square meters of duct or more can be tested.
Results in any desirable unit such as cubic meters per second per square feet is read directly off the gauge. Or, use the test to complete and automated test then have the software generate an EN12237, FE E51-767 or DW/143 compliant report that can be easily customized with your format, logos and even pictures of the test. Users love the set up and test speed.
One tech can take this tester to the jobsite by taxi or train. An industry first as is the ISO 17025 accredited calibration.
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.
9 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
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.
