The INFCR series has been discontinued. As a possible upgrade, please check pTDP series, or consult sales to inquire about remaining inventory or get advice on possible alternatives.

NEWPORT INFINITY® "C" series feature the biggest brightest display of any 1/8 DIN panel meter. The user can select the display color: RED, AMBER, or GREEN.

Panel Meters with Relays and Analog Output
The unparalled accuracy of the NEWPORT® Electronics INFINITY® signal conditioning is available in an economical series of Panel Meter/Controllers. The NEWPORT INFINITY® "C" series of meter/controllers feature a four digital display plus optional dual 5 amp Form C relays and a choice of isolated or non-isolated analog output. The scalable 0-10 Vdc, 0-20mA, or 4-20 mA analog output can be used as a retransmission of the display value or as a proportional control output as required. The microprocessor based INFINITY® "C" series includes instruments for Process (DC voltage and current) Strain Gage, Thermocouple, RTD, Dual/Differential Thermocouple, Dual/Differential RTD, pH, ORP.

The INFCR-B accepts 3-wire 100 ohm platinum RTD inputs (alpha = 0.00385) and has an accuracy of ±0.5°C. Standard features include resolution of 0.1° or 1.0°, °F or °C indication.
