Model 238A is a small battery operated instrument designed for general physical and biological testing for safe electric field intensity levels up to 25 kilovolts per meter in the vicinity of high tension AC transmission equipment. The plates attached to the top and bottom of the instrument are the sensing electrodes. An 8-foot telescoping hot stick handle is supplied to limit field distortions created by the individual performing the measurement.
