This versatile all stainless in-line thermometer features a 3" dial, 0 - 220 F. range, and ½" female NPT in and out fittings. Designed to monitor wort temperature coming out of a heat exchanger or counterflow chiller, this screws directly onto the wort out fitting on any heat exchanger or counterflow chiller with a standard ½" male npt outlet. Also fits the outlet of a March Wort pump.
The stainless thermometer is screwed into a stainless cross fitting, that has ½" female npt ports all around. A stainless plug is provided for plugging the output side you do not use. Be sure to use teflon tape when installing this on your chiller or pump.
