Analog Loop Calibrator

[fasacrifice]

Hi All,

I'm looking for an analog looop calibrator/trobuleshooter for current/voltage. There are so many kinds and I have no experience with them. Any suggestions?

I think these guys are the best you can buy

Thanks but it seems they have separate devices for voltage and current. I prefer to use only one for everything. And also some webpages say they are discontinued.

I'm sure they have both. It's a high end calibrator

Does it all

Or the 1048 model

something cheaper for sure

It looks like doing pressure calibration. Am I missing anything?

Acklands Grainger might have something from

on-hand for less than $1000.

More to chose from. There is a generator only at the link also.

if you like to make it yourself, find here in forum 317 with 10 volts and 24 mA.

Thanks for all the comments.

I think I'll go with this one,

http://www.amazon.ca/Extech-PRC15-C...&ie=UTF8&qid=1454001740&sr=1-1&keywords=PRC15

It's pretty good price compare to other online sellers. Hopefully they will ship though since it's out of stock right now.

Any comment on this one?

1) You get what you pay for.
2) The price of a calibrator is one thing. The cost to have it re-certified every year (or whatever the calibration interval is) is not insignificant.
3) For pressures, it is hard to beat a dead-weight tester. Digital meters are okay for quick checks, but in many cases are not usable for actual traceable calibrations.
4) Do you need to worry about temperature?

As an aside, I can't think of a single point at this facility where we actually care about 4-20ma or 0-10V even. We care that the operator displays and recording equipment indicates the proper values.

I won't really use that for as an actual calibrator. Mostly for troubleshooting. Don't need any temperature mesurements.
