RTS and PFD conducted trials with various so called freezer graded terminals manufactured from a range of RF providers. Deficiencies were identified in various areas, either rendering the product totally useless or only usable for a limited amount of time.
Together, PFD and RTS determined the best solution would be to design a cost effective freezer grade handheld terminal. As a result, RTS developed the RTS Tracer 4 freezer grade handheld terminal.
The product was designed to include additional features suitable for a cold store environment such as a heater unit, auto demister, fog proof lenses, continuous use at -30oC, and a useable battery life of 3hrs.
RTS also provided Tracker 4 freezer graded forklift mounted terminals with freezer graded rugged scanners, to work with their Crown reach trucks at -30oC. Both their handheld and vehicle mounted terminals communicated via a CISCO wireless LAN that was also provided by RTS.
