PIECAL 520B & 521B Thermocouple Source With the PIECAL 520B or 521B you can check & calibrate all your thermocouple instruments. Connect via a miniature thermocouple jack on the top end of the source. Use your own thermocouple wire connectors or order one of the wire kits for easy operation out of the box. • Take it into the shop, plant or field Carry it without worry - protect it with an optional rubber boot and rugged, low profile switch. Easy to operate even in the dark areas of the plant with the backlit display. • Source one or fourteen thermocouple types Choose the PIECAL 520B if you have only one type of thermocouple connected to your instruments or the PIECAL 521B if you have multiple types of thermocouples. • Calibrate directly in temperature (°C & °F) Stop carrying around a millivolt source and thermocouple tables. The PIECAL 520B/521B works with the thermocouples you use including types J, K, T, E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) and P (Platinel II). Easily set any value quickly to within 0.1° with the adjustable digital potentiometer “DIAL” plus store any three temperatures for instant recall with the EZ-CHECK™ switch. Or calibrate from -13.000 to +80.000 mV. • Compatible with ALL process instruments No competitor’s calibrator is compatible with as many process instruments! Connect directly to the thermocouple inputs of smart transmitters, PLCs, DCS and multichannel recorders and verify their outputs or displays. Works with older instruments and newer multichannel instruments that switch between input channels. • Evolutionary design PIECAL Calibrators are designed and built by members of the same team that designed and built the calibrators manufactured by Fluke* under the Altek* label. The PIECAL 520B/521B improves upon other brands by including backlit display with larger digits, rugged switches and a battery compartment for fast battery changes. Add an optional rubber boot with tilt stand for extra protection on the plant floor or in the field. * PIECAL Calibrators are not manufactured or distributed by Fluke Corp or Altek Industries Inc, manufacturers of Altek Calibrators.
