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.
