Series DT-8300 Digital Thermometers
DESCRIPTION
SPECIFICATIONS
The AMETEK DT-8300 Digital Thermometer is a
rugged, field
instrument
designed for
dependable,
worry-free
temperature
measurement
anywhere in
the plant. This
unique device
can be used
with any Type
K thermocouple
to provide
quick,
convenient,
Model DT-8300
continuous
monitoring of liquid and gas processes.
t The DT-8300 is ideal for use in hard to reach
places such as overhead pipes since it can be
mounted remotely from the sensor by use of
thermocouple extension wire. Four configurations
provide for wall, pipe, panel, or stem mounting.
The stainless steel housing and one piece VALOX®
bezel/face provide a corrosion resistant package for
harsh environments. This device performs reliably
over a wide ambient temperature range.
t The large, easy reading LCD display features low
power and open sensor indication. A self-powered
version is available incorporating commercially
available size AA batteries for approximately
1.5 years of continuous operation. An external
power model is also available for operation with
an unregulated 6 to 28 VDC power supply. The
DT-8300 is also inexpensive, priced far less
than comparable electronic field temperature
instruments.
