Thinking of ordering this http://www.trutechtools.com/PRH2 can anybody tell me if its dependable.

It's a little slow on measurements but I've had mine since they came out and it's held up good. Good for a quick check. And the price is a lot better than it use to be.

I'm on my 3rd one, replaced twice under warranty. Both times it died in my tool bag, no drops, decently protected when stored.
It's ok for walk around readings, but the insertion depth is to short for it to be useful for in duct measurements through a test hole.
My advice is to either get a SRH3 or SDP2, or get a Testo 605-H2, and secure the battery door with tape.If more government is the answer, then it's a really stupid question.

Due to the stupidity we have here in Texas of ducts and air handling equipment installed in attics, especially furnaces with uninsulated blower compartments, I frequently run into situations where I can't really get good coil entering air readings with an instrument that has a 5" insertion, like the Testo 605-H2 Humidity sticks, so I'm ordering a Fieldpiece SDP2.If more government is the answer, then it's a really stupid question.

Your probably right. The price is right and I like the idea ofkeeping it handy in my shirt pocket but, I might just hold off and get a quality psychrometer.

You can't even keep it in your pants pocket really.
Instead of making it so the aluminum protective cap screws onto the aluminum body, so it would be like one rigid tube, they made is so the cap threads onto the base of the plastic probe part, which is glued into the end of the aluminum tube that acts as the housing. If you put it in your pants pocket, and sat down, chances are the probe end would break right off, protective cap and all.
It's one of those tools that was a great idea, but poorly implemented for field use.

Yea, it sounded good but I was weary about it. Thanks for all the info

Now that I've savaged it over its physical shortcomings, I have to say that I like that it will do Dewpoint and wet bulb calculations. I'll never understand why Testo didn't make the 605 do both, instead of making 2 separate instruments.
The sensor in it is also quite accurate, at least as good as any others I've used that were under the $500 range.If more government is the answer, then it's a really stupid question.

Has any one tried the SDP2 yet? I have been thinking about getting 1 but thought I would see how they were working out.
