255-212 Floating/Submersible Min-Max Thermometer  
255-212 Floating/Submersible Min-Max Thermometer  

The 255-212 Min-Max Thermometer can be configured as either a floating or submersible thermometer for measuring the minimum and maximum temperatures of water, such as in an evaporation pan. It features a u-tube thermometer mounted on a non-magnetic base. The built-in solar radiation shield protects the thermometer against direct sunlight, as well as providing protection against breakage.

In a float-mounted installation, two floats are installed on the thermometer base to float the thermometer approximately 1/4" below the water surface. The thermometer is then attached to an anchor using flexible lines at least 10" long, but short enough to keep the unit approximately one foot from the edge of the pan and the gauge.

In a submerged installation, the thermometer base rests on the bottom of the pan. A non-magnetic handle is fastened to the bulb end of the base and hooked over the edge of the pan. The thermometer should be located on the inside-bottom of the south side of the pan (in the northern hemisphere) to ensure that the thermometer bulb is shaded as much as possible from the direct rays of the sun. The thermometer must be submerged gently to keep the small indicators inside the thermometer tube from being moved away from the mercury column.
