Specifications
DPI 820 Dual Input Thermometer
Two sensor inputs, T1 and T2, allow individual measurement or simultaneous comparisons. For differential
applications; e.g. heating boiler bypass, T1 minus T2 can
be displayed
Interchangeable Probes and Wide Thermocouple
Compatibility
Allow general temperature measurement or the use of
special sensors for demanding applications; e.g. high
temperature, hygienic and aggressive media
Temperature Test and Measurement
Periodic Data Logging
Records processes and systems over time
Manual Logging
Record screen snapshots for batch sampling and environmental monitoring. All data is date/time stamped.
Review Data
On-screen or upload to a PC via RS232 interface (see
accessories for lead). No software purchase is necessary
as standard Microsoft®applications provide data transfer (HyperTerminal) and analysis (Excel). Alternatively,
print directly to a compatible serial printer.

Intelligent Digital Output Sensor (IDOS)
Universal Pressure Modules are available from 10 in H2O
to 10,000 psi (25 mbar to 700 bar).
Total Flexibility
IDOS modules can be used with any compatible instrument; for example, a DPI 820 thermometer can become
a fully featured pressure indicator or can read pressure
and temperature simultaneously.
Plug and Play
Modules are interchangeable between instruments,
requiring no set-up or instrument calibration.
