Fieldpiece

[northstarair]

The SC77. The sheer jump in quality and trust in my meter has been significant. Next fieldpiece purchase will likely be a set of SMAN3 or SMAN4 manifolds. Probably in a few months

Still got my 8 year old SC66...works every time.

I have been using a SC76 for over a decade... just found the DC volts does not seem to work well anymore. Would not have known other than checking a battery... never use DC volts.

I have an SC77 for a backup... rarely use it. One of these days the 76 will die and the 77 will become the main meter.

This is my personal favorite

Besides the price, what is the difference between the SC56 and the SC55?

edit: The video explains the difference at the very end. I think I'm going to go with the 56 even though it's a bit more in price. I like the inrush current feature.

I have a question concerning the SMAN3. On my third one due to the high side malfunctioning. Any truth to what I have been told about nitrogen causing issues with the sensor(s) ? I have heard about others having the same issue.

Inert gas causing issues........ Never heard that one

I always flush my SMAN3 with nitrogen after each use, and have never had any problems with the sensors! I know a few people with SMAN's and most of them flush with nitrogen after each use and never have had problems. Maybe check your Nitrogen regulator or maybe the hose for some type of contamination?! Just trying to help out if I can.
Good Luck

I know I am throwing gasoline on the fire... sometimes it is fun...

My DC is 7+ years old... I have ABUSED the sensors to death (hit with pressures over 500#, pulled vacuums through the manifold then hit with release of refrigerant, sensors have never been cleaned, never flushed the manifold)... not a single issue with them.

What was the name of that brand ....? ....Diggi Spew?

(ga-hvac-tech, it's also amusing to throw in a rejoinder..)

[SBKold]

Yeah that's exactly what I want to do......flush the manifold each time? Nope.

Yeah, it just keeps spewing out ACCURATE readings day after day after day after day after day... All I have to do is change the battery 3-4 times a year.
