Testo 510

Battery life excellent

Have used it when it’s -20 outside and it works.

Arguably the 510 is one of the few items Testo makes which is actually really good.

I would advise against the Fieldpiece, a couple guys at work have bought them and all have had problems with them.

 

does it start out in " of WC or do you have to scroll to get there ?

how is the magnet on the back ?

like the design and fairly compact ....

 

Im not sure which number it is, but its the FP dual port manometer without the pump feature. Its a solid manometer, its what I recommend for all the techs that ask me.

Displays differential and port 1 or 2 pressure.

I like it cause I can measure 2 things at once on 1 meter

I do burner work, so I always need Pilot and manifold separately, or manifold and regulator output.

On a blower test, you would see TESP for differential, and then push P1 for return, and P2 for supply pressure, and have an accurate reading for both.

You do have to 0 it when you start it up.

What I dont like is that Auto off has to be set every use if you dont want the feature.

I believe it will go to 60” - which is roughly 2 psi.

If you only want -5” to 5” and no zeroing, you can not beat a Dwyer Magnehelic gage with the portability kit.

I still have my 5 " WC Dwyer Magnehelic, well built used it for years, still works, that is what I use to check my inducer motor pressure because the reading is stable .... sometimes you just get tired of looking at the same instrument / meter / gauges year after year .....

 

All digital meters that are not time weighted will have some bounce on a pressure that is not totally stable.

I keep a 510 with my CA. the 510 will drift. If it gets tilted while checking pressure your reading will be affected. For a final reading I disconnect the hose from the 510 port and zero it. I also have the field piece sdmn6 and it will drift, but not as bad as the 510. I use the field piece for TESP testing and some manifold pressure checks if the CA case is in the van with the 510 in it.

 

All digital gauges are inherently bouncy, just their nature to respond to exactly what they read. Where as a fluid filled gauges or a fluid filled u-tube manometer will have a very slow dampened reading.

I own the Testo 510 and love it.

I also own the ABB (now CPS) SPM100 which I also enjoy. I use this one when I am dealing with higher pressures since it will handle upto +/-70"wc. So nice when working on elevated 2 pound systems.

I put together a video a few years back on this subject:

thanks for the link, and for making the video ..... so which one are you using now a days ? probably would not want want to have to use a smart phone however ... kinda smart phoned out with my Appion pressure gauges and CPS scale ....

 

I still use both, the issue with the ABB is that if you do not remove the battery it will some how eat up the battery and that battery is not easy to come across when you need one quickly. I still use the same exact Testo 510, thing is bullet proof.

 

I notice you have the Fieldpiece dual port. You did not like that one?

When the readings are bouncing. I use a snubber , in-line with the hose.

I know about pressure snubbers but never seen one for inline flexible tube use, what are you using?

 

Well heck now that I opened my mouth and said that, I can't find it. I think it was something that I pilfered from one of those generic pressure switch kits. They had come with a variety of little orifice sizes and I just jammed it down inside a piece of tubing and it worked pretty well. I'll have to see if I can remember what that was. I can't find it in my kit so I must have lost it.

Got a 510.
Only Testo thing I haven't managed to break.
Love that little thing.
I should test it's accuracy. Got to be ten years old now.

 

I didn't think about the different pressure switch orifices that come with that universal pressure switch Supco has, the one that has different colored springs and port orifices. That is a thought to use one of those to dampen any pulsation.

 

Yeah, I think thats the kit I referred to.
Emptying my coat pockets tonight , I found a filter from a testo CA. This may work as a snubber.

thanks guys ....

 

What about making a small "tank" to hold more volume? Like a 3" piece of 3/4" PVC with caps and then thread barb fittings on it?

 

Never tried it for dampening, but we use to use that concept as a time delay in pneumatic control.

But, in this application, it may behave as a amplifier and make the pulsation worse.

this post helped out a lot thanks!

 

I’m late to this but I use the FP ADMN2 Dual Port Manometer Head on a EHDL1 Electronic Handle. I’ve used it to measure gas manifold, pilot pressures for the last five years and haven’t ever had issues except when the batt starts to die. I’m looking into getting some pitot tubes and another tubing set so I can start testing static pressure. Has a variety of heads for testing air velocity temp voltage and more.

I’m a Fieldpiece junkie I’ve only ever used their multimeter. Only issues I’ve ever had was with the ammeter clamp which broke on two separate meters. I can understand the CONS some guys have with them though having to carry around multiple heads and swap them around every time you want to test something diff. I personally carry my setup around in an old Crown Royal bag along with the tubing, adapters, Allen keys for the GVs, steel wool and a couple small brushes just to keep it all in one spot
