This version of the 237 has a connector instead of pigtails for connecting to the MetData1 or CS110 Electric Field Meter. The 237 is primarily used to determine the percentage of time that a surface (i.e., leaf surface) is wet versus dry. The 237 is intended to emulate a leaf surface. The measurement is made by determining the electrical resistance on the surface (a wet surface is less resistant).
