This is a $20 thermometer attached to $50 worth of standard brass plumbing fittings, some of which I had to discard for my application. I use it on my kitchen faucet when I develop film, swapping it for the pull-down spray head on my Grohe faucet (on that faucet the spray head screws into a standard 1/2 NPT collar so that is handy). It is so heavy it pulls the hose down into the sink, and so long the nozzle end sits pretty low even when hose is retracted. I substituted a 1/2 brass double nipple for the upper elbow and hose fitting, which saved weight and shortened the unit. The thermometer only resolves to about the nearest degree; I calibrated it against a ThermoWorks ThermaPen and it varies a degree or two; when full precision is needed I check baths against a darkroom thermometer. Still, the Water Temp is useful to get the water flow close to the right temperature without needing to hold a thermometer in the flow, and the shutoff valve on the end lets you leave the temperature valve set which saves time. In a dedicated darkroom with a faucet with outlet threaded for standard 3/4 fitting, this Water Temp unit would be a natural choice and much less expensive than a lab-style temperature faucet. After several trips to the hardware store and experimenting with a variety of fittings, it now works okay for my kitchen application and is worth using despite the somewhat awkward handling. I could probably assemble my own from hardware store fittings and save a few bucks but at this point it works and the saving would not be worth the trouble.
Hose attachment broke before i even had a chance to use it
