Should I keep the sporlan, I may grow to like it, and get a testo as well? You like both, right? When do you use each?They both do what I bought them for.I prefer the Testo display because it's simple yet effective. Also they are priced at $400 and don't include physical gauges, a manifold, a view window, charging/vacuum port, valves, or hoses which the Testo 550 does for under $300. These are sweet toys that aren't actually good to use at all. A real pain that overshadows the cool-factor.Īll this added up to one thing for me. anywhere but crouching at the unit or standing next to it.ġ0) The sensors auto power off right as the pressure/temp is getting good, then I have to find the button again, wait 30 seconds and reconnect. Wireless is cool if I can get the signal at my truck or indoors or at the condenser. With range like that an some $10 binoculars, I could use a regular gauge kit and achieve the same effect. Not sure why the difference, perhaps it is "product development"?Ĩ) After pushing the button to turn them on they blink right away like they are on but are not connectable for a tiresome 30 seconds while I am crouching by an A/C unit.ĩ) The range is about 10 feet. Not a big deal if you do it once, however they keep turning off and when I need to reconnect, I inevitably reverse the hi and lo temps.ħ) One of the temp sensors has a nice contact sensor and metal plate the other has a cheap cylinder sensor. I know that his is a reach since normal gauges do not have it, but why not provide it? Furthermore, regular gauges do read negative pressure in units of 1 mmHg for "coarse vacuuming"Ħ) The two provided temp sensors show up with the same name and some serial number so connecting them is hard. If I am committing to a manifold, then I might as well get a bluetooth manifold.Ĥ) How to charge/vacuum/recover? An NPT tee contraption would add a port to these however, that would not fit in many situations returning me to hoses and a manifold again.ĥ) There is no micron gauge provided. That was that they are small and easy to clip on and no hoses to manage. Not an issue with a 45 adapter, I imagine.ģ) Tried these on a manifold with hoses and they work okay however I realized that I defeated my purpose in buying these. Usual hoses have a 45 degree end plus thier diameter is the 1/4 flare. I had my own and it worked.Ģ) The NPT to 1/4 flare adapters (the provided ones and mine) are straight meaning that due to the diameter of the sensors, I cannot access two of the fittings that I tried. If you have any problems with the registration process or your account login, please contact support.ġ) The provided NPT to 1/4 flare adapters do not depress the schrader valve on the two units that I tried this on.
