Fieldpiece SMAN360 3-Port Digital Manifold with Micron Gauge

This instrument is all that a hardcore handyman needs to become his own capable a/c repairman. I knew virtually nothing about a/c systems... this instrument singlehandedly showed me the way to salvation without any outside help. Easy to understand instructions and explanations; this device is extremely intuitive to operate. I wish I would have done this a long time ago. I am totally impressed..... and, it is fun to use; makes you feel like you are in control of the bridge on the starship Enterprise. Its never too late to start.I marked the positive sides of the K-plugs red so they can be plugged in quickly without error; otherwise you have to look closely in bright light to see the pin size or polarity markings.This fine instrument deserves a hard case to protect it; it comes with a cloth bag that is really a "joke." Be very careful where you store it so it won't get broken. I found an old lap top case that is way better protection than what comes with this tool. It needs protection.

I'm a automotive hobbyist but for a living I'm a Metrologist (science of measurement). I work with precision test and measurement equipment in the aerospace industry every day. The build quality of this instrument caught my eye. After purchasing this instrument, I ran this through various pressure, vacuum and temperature tests in the lab using a Fluke 1560 Thermometer Readout/PRT and a DH Instruments pressure/Vac calibrator and it was well within its published specifications on all parameters. I honestly didn't think the instrument would perform this well right out of the box without calibration. The manifold valves operate very smoothly and feel to be of great quality.I would highly recommend this to any serious tech and or a techie/hobbyist like myself. You will not be disappointed.

Revised after I posted this....Suck.......I had for two months. Quit working. High side reads 29.9 hg low side reading 473-635psi. Won't reset to atmosphere pressure. I took good care of these too......field piece you aren't what you used to be. Do not buy. Buy testos. My friends have testos. Left in rain and still work. I opted for these after careful consideration. Wrong choice. DONT BUY. THEY WILL FAIL.........after two days they started working and have worked since. I like them. I was disappointed at first because they quit. But back in order. Just make sure you don't get them wet. I'm not sure if that was my issue because the only time they got wet was about a week before they quit. I wanted to revise my review after a few weeks of them working fine

Used for just about 2 years and now screen is only showing all number eights. Out of warranty now and will cost according to FP at least 150$. That's half the cost of a new one. BTW I took good care of it, no drops,no getting g it wet, put it in the padded soft case majority of the time. Think Im getting a sporlan smart tool cuz it seems to be more rugged.

Purchased this to replace my other Fieldpiece SMAN3. This updated model has better interface. Digital gauges with auto micron gauge insure you have pulled a deep vacume. The sub cooling readings provided with the clamp on temp gauges is the only method to accurately charge r410a. One or two negatives: gauge lcd screen is susceptible to permanent damage if dropped or something hits it. This happened to my first one. I bought a case but it won't fit unless you disconnect the hoses every time you want to put it up. Also the plastic temperature clamps easily break at the pivots and render them useless. For a tool that's used for field service and costs almost $500 it is no way rugged enough.

The SMAN360 has a proven track record and comes from a lineage of solid build manifolds used by professionals. I especially like the large display, with all the information you need at a single glance so no swapping back and forth to get what you want. It's super easy to use and works with virtually any refrigerant type. I use this for both HCAV and auto AC work.

This is a different version of the sman 360 that I had purchased some years ago the original version although hard to use came with good instructions on how to use, the new version has terrible instructions the display is different and it took me a bit to figure out how to get it to calculate tsh. Also the first set I bought were defective and leaky but one call and they shipped me out another manifold thank you amazon.

I absolutely love my SMAN360. I use it on every air conditioning system that I service and it is extremely accurate when charging by superheat or subcooling. I can confidently say that it is the best digital manifold in the HVAC/R industry. Also, fieldpiece has outstanding customer service. The hook on my sman ripped out so they sent me a brand new hook and even told me how to replace it!
