ACCESSORIES (please contact Trek for addtional information)
Ion Collecting Plate Tripod
This portable tripod can be quickly configured to angle the ion collecting plate between 0 and 90 degrees (horizontal vs. vertical position).
Bar Code Wand
For Trek Model 157 Charged-Plate Monitor. A bar code wand is available for applications that need to measure and record data for bar-code-identified equipment.
Thermohygrometer
A thermohygrometer is available for use with Trek Model 157 Charged-Plate Monitor, for applications where humidity/temperature measurement is important for data collection purposes.
High Voltage Cables
For its high voltage amplifiers, Trek offers double-insulated high-voltage output cables in standard length (3 meter) as well as other lengths (5 meter, 10 meter, 20 meter) for additional versatility
Rack Mount Adapters
Trek offers a variety of rack adapters for its amplifiers and voltmeters.
Carrying Cases
Please contact Trek if you are interested in obtaining a carrying case for your portable Trek unit. Our standard case is provided with the appropriate internal cushioning to address most situations (to accommodate probes, collecting plates and other accessories as needed).
AC Adapters
Trek offers AC adapters for its models that require an AC adapter. The adapters can also be used to charge the internal rechargeable battery of units containing such batteries.
