Modifications were designed for operation on the Belfort Universal Raingage, the Leopold-Stevens Water Level Recorder, and the Belfort Recording Microbargraph. In addition, thermistor thermometers were constructed to operate at the research areas thermograph locations. Specifically, the modifications were designed to permit electrical interrogation of existing devices now being operated at the Bridger, Montana research area to provide a resistive readout. Calibration tests were conducted to verify that the instrument modifications met the design requirements. Corrections for temperature effects upon the various potentiometers can be made in analysis of the data or on site by installation of a compensation device such as a thermistor. (WRSIC abstract)
