Spanning
a temperature range of -200 to +400 degrees .C., the Model 140 series monitor alarm incorporates a microprocessor which makes the use
of various features; including varied sensor and output modes,
while preserving compatibility with the
previous Model 125 in data monitoring.
This single probe temperature alarm-monitor temperature span has various factory
set ranges, and is housed in a wall-mounted or free-standing
box. The basic unit includes alarm on high and low temperatures,
with audible and visual alarm indicators (beeper and LED),
settable mute and alarm "chirp" periods, and a UL listed plug-in power supply. Custom programming & packaging can be provided to fit most temperature monitoring tasks.
The features of the Model 140 that
make it suitable for applications such as built-in monitoring
of freezers, refrigerators, and walk-in environmental chambers
include; temporary muting of the alarm beeper for user-selectable
periods up to about 30 minutes (the beeper cannot be disabled
completely), optional relay contacts indicating a temperature
alarm condition or power failure, and for hookup to a remote
alarm device or telephone dialer.
