The OMEGA™ MDS8PT is a 1/8 DIN size (96 x 48 mm) digital
panel meter in a benchtop plastic enclosure featuring the Pt Series color-changing display.
The Pt Series meters feature
4 or 6 digit LED displays that can be
programmed to change color
between GREEN , AMBER, and
RED at any set-point or alarm
point. Other options include
isolated programmable analog
output, serial communications,
Modbus® and Ethernet.
The universal temperature and
process instrument handles 10
common types of thermocouples,
thermistors, multiple RTD’s, and
several process (DC) voltage and
current ranges.
