AK-900 just delivered.
I purchased the Digicool AK-900 digital refrigeration system analyser on Saturday through truetechtools.com.
Price was $299, included the digicool refrigerant manifold. (has 90degree turn valves instead of multiturn valves.)
They shipped it UPS ground for free.
Received it today (Thursday). Will check it out and give a review in the next few weeks.
The wiring insulation on the temperature probes is pretty thick and color coded.
I'm assuming blue is for low side and red is for high side.
Look forward to mastering the use of this tool.
I am for doing good to the poor, but...I think the best way of doing good to the poor, is not making them easy in poverty, but leading or driving them out of it. I observed...that the more public provisions were made for the poor, the less they provided for themselves, and of course became poorer. And, on the contrary, the less was done for them, the more they did for themselves, and became richer.
