The 210-4417 Globe Thermometer is used in studies to determine heat stress. A 6-inch-diameter hollow copper sphere is painted with a matte black paint to absorb the radiant heat from surrounding objects. After a time lag, the temperature at the center of the sphere is a measure of the radiant heat.
The 210-600 Water/Soil Temperature Sensor is a two-terminal integrated circuit transducer that provides a liner output current proportional to the absolute temperature.
The 225-520-A Pocket Sling Psychrometer is only 7.5" in overall length and comes with a convenient pocket-size carrying case. The two 5.5" red liquid filled thermometers are attached to an aluminum back with a handle for whirling. The handle folds down when not in use.

The 225-5230 Assmann Psychrometer utilizes two precision mercury thermometers with 3-point calibrations. A calibration certificate gives the correction required at each point. Each instrument is supplied with a wind shield, a mounting support, a syringe to moisten the wet-bulb wick, extra wicks, psychrometric tables, and a carrying case.

The 225-564 Fan Psychrometer is used for determination of dew point and relative humidity. It consists of 9.5-inch dry and wet bulb thermometers mounted on a common back, a water bottle, fan, motor, and 6-volt battery. It is easier to read and provides more consistent results than a conventional sling psychrometer.

225-7918 Fuel Moisture Sticks are used to estimate moisture content of small forest fuels for prescribed burning operations and to determine forest fire danger ratings. The exposed sticks are weighed on the 225-7917 Fuel Moisture Scale and the weight in excess of the oven-dry weight represents fuel moisture.
