There is no factual basis for this criticism of DC.
to continue to disprove your unfounded allegations.
At TruTechTools, an SMAN4 is $449.88 plus tax, so let's call it $475 to round numbers.
Same site, the Dc Ak-900 with manifold and a set of clamp sensor comes up to about $426 pre-tax so maybe $450 after tax.
Perhaps you should check pricing before you go spouting misinformation.
As to the "useful features" the DC has a feature that no other RSA has, the bar graph which shows you what is going on in the system in greater detail because of the speed at which it responds (1/4# each 1/4 second on the low side)
Can your Testos or SMANs do that?
i'd like to know when there will be digitals that use transducers to read pressure, thats when i'm more likely to spend that kind of money
Like it or not some guys like the option of evacuating thru a manifold. And most of the replacement manifolds being discussed are four port types:evacuation manifolds. That is going to to make the cost of ownership higher.
You failed to make a comparison price wise to the 550.
Bar graph might be useful to you but it means nothing to me.
My instruments react fast enough to system changes.
I go through a set of analogs once a year. It's easy to bust up a yj guage then you wonder about accuracy etc. I bought a set of ak900s and if they last me 3 or 4 years it will be about the same costwise but I won't have to worry about accuracy and its easier to check SH and SC bc the sensors are dangling right there off the guage.
I don't have the AK900, but assuming it is built to a similar standard as Digi-Cool's previous instruments, it is unquestionably the toughest DRSA on the market.
I've had my Digi-Cool BTD-1000 for about 8 years, and my DRSA-1250 for about 3 years, both work flawlessly.
My BTD-1000 has survived repeated unreasonable abuse too.
The 550 is only a 3 port, so you've contradicted yourself on the manifold subject.
Fast enough, much like good enough, seldom is. Until you've used it, you cannot properly comment on it.
With the others, you are stuck with what you're given.
I've had mine on a large, clumsy 4 port before, too. Didn't like it, so I went back to the good old YJ41. It's another nice feature that no other DRSA has
:confused: I thought the AK-900 was under 300
