DP750 Series

Starts at

$

33

The DP750 Series is an excellent
solution for outdoor applications
where AC power is not available
and wide ambient operating
temperatures are experienced.
Using a 3 V solar cell, the DP750
will operate with as little as 35 lux
(lux is a measure of light; a
comfortably lit desk is
300 lux). For example, the
ability to operate in
temperatures as low as

-37°C (-35°F) allows the
user to monitor
temperatures of pipelines
in remote sites. Other
applications include walk-in
refrigerators/freezers and
photographic apparatus. Since it
is self-powered, the DP750 can also
be used near hot tubs and pools
where electrical safety is a concern.

The new DP751A series is a 57 mm
(2.25") square, solar-powered LCD
meter with a switch for °C/°F display.
The DP752 is available in an AC
powered model for use in
applications which require a bright
LED display and a wide ambient
operating range. The DP753 is a
rectangular flush-mounted,
solar-powered LCD meter with a
standard thermistor sensor with a

1.5 m (5') cable.

DP752 (flange mount included)
with 46 mm (1.8") stainless
steel probe (calibrated
and not interchangeable),
shown actual size, $40.
