Greenville, S.C.-based Hitachi High Technologies America Inc. and its Systems Products Division is moving its temperature-sensor systems deeper into produce applications.

The company plans to showcase the products at the National Restaurant Association Show May 20-23 in Chicago.

Hitachi says its HiQ eSystems environmental monitoring and reporting systems can help protect perishables. Two new products — Glacier, a temperature-only sensor system; and Storm, which monitors temperature and humidity — will be on display at the NRA show, said Ashlyn Byrne, spokeswoman.

“The main focus is restaurant coolers,” Byrne said, although she also said the tools have applications in semi trailers during shipping as well.

Bringing the products to the show is a way to introduce them to restaurant operators, as well as produce-focused distributors, Byrne said.

“They’re durable for extreme temperatures,” she said of the sensor systems.

A third system, Volcano, is still in the “prototype” stage, Byrne said.

HiQ eSystems provides the ability to monitor data remotely, as well as the flexibility to remotely configure the frequency of data collection and transmission, reducing travel and labor expenses, Hitachi said in a news release. Data can collected all day, 365 days a year, even during power outages.
