The DP9602 provides precise platinum resistance
thermometer temperature measurement and logging
for exacting applications in both laboratory and site
locations. It is an exceptionally accurate and stable

DP9602 shown smaller
than actual size.

digital thermometer particularly suitable for use with
thermal calibration baths as a reference standard.

The DP9602 is fully characterised for Pt100 sensors
and all major thermocouples J, K, N, T, E, R, S and B.
Exceptionally stable automatic cold junction
compensation with a rejection of 100:1 is incorporated
for thermocouple ranges. Alternatively, external or
manual referencing can be selected as required.

Applications include medical, pharmaceutical, food,
environmental testing, R&D and educational
establishments.

Displayed values and user information are indicated
on a bright clear LED screen with diffused backlighting.
Data can be displayed in °C, °F, K, Ω as required;
nine front panel push keys, the only user controls, are
used in conjunction with the display screen. It is this
arrangement which makes for very simple and
“friendly” operation. There are four input ports, two for
thermocouples and two for 3- or 4-wire Pt100 sensors;
the instrument automatically recognises 3- or 4-wire
configurations. The DP9602 can accept two Pt100
sensors and/or two thermocouples of similar or
different types. The measured temperature can be
displayed directly from one of the inputs or
differentially between similar or different inputs.
Differential temperature and the two individual channel
temperatures are displayed simultaneously.

All four inputs can be scanned and values logged
according to parameters set up by the user in the
PC software; the instrument incorporates a real-time
clock and on-board memory. A flash drive USB port is
provided to allow data to be stored and/or exported.
PC software running in Windows® is provided as
standard; it allows programming of custom calibration,
remote control and measure and logging functions.
