PRELIMINARY EXAMINATION

GENERAL DESCRIPTION

HI142 series is a family of temperature dataloggers especially

designed for applications in supermarket shelves and ware-

houses. It is possible to monitor continuously and simultaneously

the temperature condition in up to 31 locations.

They can all be wired through RS485 to the HI504903 GSM

supervisor or to a local PC, allowing data downloading

without removing the loggers from their sites.

Moreover, with HI504903 GSM supervisor it is possible to

receive SMS when an alarm occurs (low/high temperature,

low battery level, etc.) or upon user request.

The user can interact with the meters through a PC using the

HI92140 Windows

compatible software for setting High and

Low alarm thresholds, logging interval, logging delay start,

alarm mask time, lot ID, etc.

The logger can memorize up to 7600 samples (i.e. stops

when memory is full) and can also work in a cyclic way (i.e.

old data are replaced by new samples when memory is full).

In case of power failure, an internal battery assures a

working time of at least 1 week.

The status of the logger is indicated by the 2 front LEDs

(green and red) as follows:
