Jim, one thing to be aware of, if you get the Delta 1 temperature monitor unit--it looks like you can take it apart easily, if the connectors don't suit you, but you can't (except for the shutoff valve on the bottom, which I've replaced with the 4-way hose manifold). It's all sealed with permanent Loctite or something. It's garden hose connector in, and garden hose connector out. The only specialized part in it is the thermometer dial, which screws into a 1/2" IPS female pipe fitting, so if you could get that from the source, you could build it any way you want. The brand on the dial is "Powers Process Controls."
