Doric 473/475 Series Portable Digital Calibrators
Doric Model 473 and 475 Digital Temperature Calibrators use custom VLSI integrated circuits in a patented circuit design to deliver exceptional accuracy, high reliability, and long battery life in a truly portable, handheld instrument. Large, touch-type switches and precision adjustment control let you access multiple functions quickly, and because you can both simulate thermocouples or RTDs and measure corresponding transmitter output with one instrument, calibration is faster. Other features that increase your productivity include direct readings in both °C and °F, without additional modules or conversion tables. Independent, simultaneous zero andspan adjustment functions eliminate repetitive readjustments of instruments being calibrated. Rugged package design and complete fuse protection insure reliable use, year in and year out.
