Beautiful desk there at the beginning. Is that an acacia butcher block? I have 2x Uplift bamboo standing desks. For me they've proven to be a big improvement for ergonomics, both with standing _and_ sitting, particularly for the precise height adjustment so you can align everything just right.
I think what you described as a gauge pressure sensor would actually be called a sealed gauge sensor. Normal gauge sensors measure pressure relative to the surrounding ambient pressure; you can also do a gauge measurement by leaving one hose disconnected. Sealed gauge sensors measure pressure relative to a sealed volume that's set during manufacturing. Absolute pressure sensors are similar but have an evacuated volume for their reference pressure.
Comment regarding the accuracy alone....DM32 is 1% of reading or 0.15 Pa. The DM32X and Solo are dependent on conditions, but range from 0.4% to 0.9% or 0.07 to 1.0 Pa. $80 Dwyer Magnehelic can have 1% full scale accuracy. Accuracy is not really the issue.
@@HomePerformance looking at the Dwyer 2000-00, which is 0 - .25 inwc, accuracy is +/-4% of Full Scale (or +/-2.49 Pa), and +/-2% (1.24 Pa) for high accuracy model.
What do you suggest for an affordable infrared camera? That's one of the last tools I really need as a residential HVAC designer. I finally signed up for the HVAC list. Thanks Corbett!! I still use your static pressure video every week with customer.
How could I use this (or something similar) to know when my passive MUA damper has gone bad? It’s located in my vented attic so kinda hard to physically check it often. I’m assuming I would need to poke one hose outside the house somewhere? Can this unit just sit on my vent hood and give me a permanent reading? Thanks for your time.
No need to poke a hole, just close the hose at the bottom of an exterior door. You should see the pressure go way negative when the hood goes on, then pull back toward zero (but never actually zero) when the MUA opens.
I like to think I can appreciate a quality tool, but for a homeowner $400 seems really steep. Maybe I am just cheap or underestimating the long term use case for a Mamometer of this quality for a homeowner?
I have several clients who have purchased $3500 blower door kits for personal use. If you’re doing $25,000+ in home projects, it gives peace of mind to know it’s done right.
400 bucks may seem like a lot until you look at what it costs to build, I could probably make a good guess at the sensor they are using inside; trust me, it's not cheap to make something that accurate.
Nice of them to add that to their quiver. Personally opinion though, I love the TEC brand and the people in the company. Just find their equipment more user friendly and they came up with the TrueFlow which is very nice. But to each their own Grace and Peace Slick
@@HomePerformance Good to hear back from you. Hope you and your family are doing well Have got to hook up with you sometime. After watching the mechanicals on “the build” have a question I’m just itching to get your thoughts on. Grace and Peace Slick
For those of us that are cheap- there ARE manometers for $40 or so on Amazon that have Pascals as an option. If it’s just for your own house definitely worth the investment at that price. Is it super accurate and certified? Who cares, you get directionally useful info for almost nothing.
I just ordered mine last week. Along with a Miele dryer.
NICE

Yep, that’s exactly what I got. First desk I ever (not found in an alley or on craigslist)
Got mine last month. I then went to Harbor Freight and purchased a small case with foam inserts that you can modify to fit your tools. $13
Awesomeeee so happy retrotec made it I’ve been hesitant to buy the T E C just cause I like having my tools matching lol

And the magnahelic needs no battery, and useful as panel mount for clean rooms, etc.
No, the $80 Dwyer magnahelic is +/-3% accuracy, fyi
@@HomePerformance "standard magnahelic: +/-2% of full scale...high accuracy model: +/-1%."
@joeshmoe7899 well 3% straight off their site, and high accuracy is a custom config, not $80

Id like to see a video on affordable cfm tools for hvac and erv systems. Quality professional ones can be over $1500. Great video as always.
Cool Todd, on the list

Awesome KP- I’d get the Hikmicro Pocket cam from Trutech Tools, high res, on a lanyard, and if you upgrade later you keep it for client use.
Love my solo!

TEC is excellent agreed

Come to a patreon hangout buddy, would love to talk
When you say manometer, I hear Mahna Mahna... Doo Doo de doo do. Muppets!
