The Fieldpiece SDP2 dual in duct psychrometer overview showing how to measure differential enthalpy and calculate field capacity quickly and easily.
I love all your presentations Jim. Love the SPD2
Thanks in advance fr your business. We have been very happy with Fieldpiece so far. They are really leading the way right now with the quick innovation of products.
SPD2 has become my new favorite tool. Great job on the video
Great Job Jim!!!
Fieldpiece is really stepping up their game!
This is a great tool!!
every time I learn something new.from you.
Yes, that is correct. TEET is Target Evaporator Exit Temperature. If the temperature is too high, lower the speed to drop the temperature.
Thanks for this vid. I'd really love to see yall do one with the sdp2 linked up with an Sman460 on a system that needs adjustment to see how well they work in unison.
Thanks Jim. Great video as always.
Great video, can you please give me a link for those hole caps that you placed in the airflow test sites?
Beautiful duct work.
When doing the target evaporator temp measurement, do i need to be close as possible to evaporator? I'm talking a few inches? the reason i ask it because when i used to take enthalpy measurements i was told by manufacture rep to be close to evaporator as possible. I recently bought this item and want to make sure I'm using it right, thanks
Excellent Job!!
Thanks, it performs well also.
This is just great.I only have one question. I always take the dry bulb outside and wet bulb inside. With the SDP2, can I take dry bulb and wet bulb directly on return for wet bulb an dry bulb on supply? I just bought this instrument from true tech tools. Thank you for your good work
I love the SMAN460, I think it is one of the best manifolds on the market because it has everything that a ac tech needs but when you connect wireless with the HG3 you can't see the superheat and subcooling with your wireless screen and you have to syncronize the tools every time you use them, the distance does not give more than 60 feet in open areas and with no walls or ceilings.
I spent around $1800.00 on these tools, the SMAN460 manifold,SDP2,SC57,EHW4,HG3,ARH4,ATH4, first every time when you use the HG3 with any tool you have to pair them,the distance does not work any more than 55 feet,I have called the fieldpiece tech support 3 times and haven't recieved a good answer, they told me that the batteries may be bad, I replaced the batteries with 3 different kinds, duracell,energizer and enelope. Enelope are a very good rechargable batteries and I'm still not getting more distance.
I may not be doing something correctly using these tools but so far nobody has told me what I have to do to make these tools work the way fieldpiece advertised.
I would appreciate it if anyone has an idea on how to make these tools work properly
oscar guti Have you tried to add the JL2 Job Link? It will only work with SMAN460 and SDP2. It will add range and connects to IOS(Apple) phone or tablet for reporting.
Yes it is. I really think it is also a great teaching tool also.
California here...most my installs are attic mount systems,each offers a supply and return plenum(22"deep often)and than the ducts are flex duct(R6 insulated)my question is should or can I use the SDP2 for measurements?
Erik Cable Yes you can, placement it still key.
We deal with the same type of setup here in Houston. What would be the correct placement? Seems like there would be turbulence throughout the plenum since it is so short.
Maybe a dumb question but can you judge system performance based on just the enthalpy change.
Like if it is difficult to figure cfm for some reason.
Ie is there a target differential enthalpy range?
Do you measure return upstream, or downstream the air filter media? Thank you.
Brian Fletcher really should not make a difference as it is a enthalpy (temperature and humidity) reading, not pressure.
Good stuff!!!
What do you use to drill the test probe holes? What do you use to fill them?
Aaron Calhoun I use a stepped drill bit and foil tape.

where did you get a btu output of 4.5?
SOLD !
The 4.5 comes from .075 lbs/ft3 x 60 min/hr. so for you it is .064704x60=3.88 or 3.9 like you said.
well will it work in flex duct. in az thats pretty much all we have
Awesome!
Hi thanks for your tutorials, but please answer LUC DUMOUCHE, question......l need that answer, l have the same question
........David
please explain where i get the ht (4.5) from
Raymond Hufault 4.5 is a conditional constant for air density and can be adjusted in abnormal air density conditions
is 4.5 a fixed number in the formula
Raymond Hufault it is the the typical air density constant of .075 x 60 based on sea level "standard air" and may need adjustments based on specific air density conditions
nice
Why are all these AC test tools out of focus? Seems like the industry doesn't understand cameras.
Koyote Kola the early 2010’s seem like 100 years ago as far as camera quality! Our upcoming videos will be much better!
@@TruTechTools True. One of the problems with YT videos is that many of them aren't clear as to when they were made.
I'm sure AC tools have changed a lot since the early 2010s. Consider pulling this video when a new obsoletes it.
