The DP3002-J, -K and -T are low-cost 4½ digit
(±19,999 count) thermocouple meters with 0.1°C or

0.1°F resolution for indication-only applications. High
accuracy is provided by five-segment linearization and
matched, graded components for each T/C type.

STANDARD FEATURES

Mechanical features include a bright 14 mm (0.56")
display, a screw-terminal barrier strip for signal and
power, and a compact ¹⁄₈ DIN case that requires
less than 104 mm (4.1") behind the panel. Electrical
features include cold-junction compensation, jumper
selection of °C or °F, and a linearized recorder output
of 1 mV per degree.

OPTIONS

Power options include isolated 9 to 32 Vdc and
26 to 56 Vdc. A splash-proof lens cover which meets
NEMA 4 (IP65) requirements allows the DP3002 to be
used in harsh industrial environments.
