Pond Thermometer

This accurate pond thermometer is constructed for durability in an ABS molded tube case. The thermometer has a sealed-in, blown-glass tube and can be easily attached to land with a tear-resistant 36" polyethylene rope. 6-3/4" long. Registers 20-120°F or 0-50°C.

As the seasons change and pond water temperatures rise and fall, so do the nutritional needs of koi. To make the proper adjustments in koi diet and portion size, you need to use an accurate thermometer to measure water temperature on a regular basis.
