    Multiple compressor system etc.

    The iManifold is much more intuitive than the Fieldpiece HG3 (that's what you will need for wireless or any info gathering with the SMAN4's). I found the learning...
  3. Imperial iManifold Digital Refrigeration Gauge

    There is really no comparison. The iManifold dwarfs the competition in features. Too many to list.

    How bout the biggest one yet? Estimated airflow via evaporator coil Enthalpy/performance. And...

    Andriod users, looks like the newest iManifold update is available.

    Apple users (like me), we have to wait a few more days until the update is posted to iTunes.

    Sounds to me like male connector is loose in the housing. This can cause a poor connection to the internal circuit board inside hence the erratic readings.

    TESTO OR SMAN

    I have had the Testo 550's, SMAN4's, along with many other digital gauges.

    But lately I have really gotten attached to the iManifold. It's been awesome tool. It has a higher price tag but it also...

    I think one thing to remember is air flow has and continues to be very difficult to measure. A blower curve and an in-duct anemometer traverse is also just a good estimate. None of these methods are...

    Well, I guess this answers my email! Haha.

    This looks great. I've always thought you could estimate airflow using Enthalpy, TEET, etc but I just didn't think it could be that accurate. You guys...

    I have the 4005 and use it with the iManifold. It's about 6 months old and has held up well. The only drawback is the jaws don't open up very wide - 7/8" is pretty close to max. Not good for...

    Not necessarily, I've had it display erratic temps due to a poor connection.

    Like I said, check everything - all solder points, connectors, etc.

    Loose connection. Check the connector where it plugs into the face.

    Also, check the connections inside the head as well.

    Cool. I've had my eye on this thing for a bit.

    Please post feedback. I'm anxious to hear how it is.

    Chuck, You're exactly right.

    The one thing NOT to be cheap on is a meter. My safety is worth the extra dollars.

    With a traditional set of digitals or analog gauges and a pipe clamp.....You're just "checking charge."

    With the iManifold....You're analyzing complete system performance.

    The price seems right...

    Going digital?

    How are you testing your clamps? Attach them to an actual piece of pipe, close together, give it 2-3 mins to settle - then compare the two readings.

    Ambient air is not a good base line for the...

    Where do you find the covers for the heater breakers? I've asked a ton of supply houses and no one knows about or where I can get them.
  25. Discussion: Expensive tools and why we need to invest in them.
