TAMPA, Fla. — Temperature controlled fleets that monitor the space in a reefer can be a little more exacting thanks to a system from Par Logistics Management, which has caught the attention of distributors such as Golden State Foods.

The company’s long probes can be inserted into a load of food, sending information in real time about the nature of a problem, location, current and historic temperature, fuel levels, alarms and battery levels. It will monitor four of the trailer’s zones at a time. And when anything is out of range, the system will send an email or text message, while information can be viewed in real time over the Web.

Data is also exposed on a website for auditing purposes, rather than requiring drivers to carry temperature guns and clip boards.

Systems cost $800 to $1200 per trailer, plus $150 per probe, with monthly communication fees of $20 to $30.
