Man,I would have to say after using analogs for so long it would be nice to have clamp on SH and SC reading. I am leaning toward the Digi's.

Originally Posted by hvac5646 yeah, Testo makes a lithium bromide and ammonia rated digital set. It was a joke. NH3 and Lithium Bromide are "niche" parts of our industry. If I worked with them, I'd probably do things a bit differently. I don't, so....

I have two smans and love them. That being said I am not a fan of the micron gauge but I do use it in a pinch. I have leaned a lot over the years from here and others about evacuating and I rarely use a manifold. I also wouldn't mind owning a set of Digis ak900 but do not have a need for a third set at the moment. I also do not use my digitals for recovery of old systems. Not really sure why, maybe just like to break out the analogs once in a while. I do know a few people with the Digicools and I am impressed. Would like to know how to use and understand the bar graph.
Why wouldn't you? I couldn't keep a set of analogs in working order if my life depended on it. I have multiple sets of digital gauges to choose from but I don't get to work on too many bastardized systems like you are describing in lower temp stuff. Thankfully about the worst thing I see these days is dye

LOL. Ok, here's my inerpretation of the OP OP: So thinking ahead to AC season and needing some expensive tools. I am trying to get the best bang for my buck. When I told my boss that I was gonna buy a digi-cool cause I need 410 gauges and temp sensor and a red box cooper and gauges is around the same price. I got the don't waste your money on a toy what do you guys think? Translation: With AC season around the corner I'm trying to decide whether to buy a Digi-cool DRSA or a set of analogs and a Cooper blue box. The boss says that the DRSA is a toy, so don't buy it. OP: I was told buy gauges and use my sensor on my $100 amp probe meter. I understand it works and is the best $ option but is a set of digital gauges better than "OldSchool" methods I have said it before I have never seen someone with digital gauges in my travels. I hope it's not like just wanting a Bigfoot for a pet. Translation: It was suggested that I just use a set of analogs and a k-type sensor with my Amprobe meter. I understand that this will work, and would be the least expensive option, but I keep hearing that digital gauges are better than the old school method, so my question is, is it really better? I'm afraid that I'll suffer from buyer's remorse when the new wears off. HTH.

Seems my comment about hvaclover was a freudian slip, since I was unwittingly replying to his nephew! That IS weird. I must have looked at the beginning of the thread and didn't remember it. Too funny. I suppose I should apologize to hvac5646 at this point. Didn't mean anything by it hvac5646. Carry on.

Correct me if I am wrong but I think the SMAN micron gauge does not begin to measure vacuum until 25000 microns. The SMAN micron gauge starts to read much lower at 9,999 microns
