    Trek Charged Plate Monitor Model——158A


    The Trek Model 158A Charged Plate Monitor is the premier instrument to evaluate the performance of air ionization systems. It features a user-friendly large 7 inch screen that is active through either touchscreen control or corresponding function keys. The compact design supports superior data collection and data storage capability. The data is displayed in color and may be stored internally or can be easily transferred to a USB flash drive or other USB device. A charged-plate assembly is required and is sold separately (6 inch charged-plate shown).
