The Practical Instruments Electronics (PIE) PIECAL 820 process calibrator packs the power of six single function calibrators into one surprisingly small package. The perfect complement to any technician's toolbox, the PIECAL 820 combines advanced features, ease of use, accuracy, signal compatibility and compact size to make it the best value multifunction calibrator on the market today.

The PIECAL 820 process calibrator combines all milliamp loop functions and sources and reads DC Volts and millivolts, 14 thermocouple types, 9 RTD curves, ohms and process frequency signals. For troubleshooting connections it has a continuity tester with tone. All ranges have auto storing MIN/MAX readings and three output set points for fast calibration of zero, midpoint and span. Advanced features include automatic detection of 2, 3 and 4 wire RTDs plus configurable automatic stepping and ramping. A LED flashes green for frequency sync and lights up red for signal overload and invalid signal conditions.

The technician friendly PIECAL 820 is all about ease of use. An intuitive EZ-DIAL Double Click Menu makes it simpler to setup than larger calibrators with their complicated button filled panels and confusing menus. Use the PIECAL 820 right out of the box instead of wasting time learning to use more complex calibrators. The toolbox tough design includes a backlit display for use in dark environments and protective rubber boot with built in stand. NIST Calibration Certificate is included at no extra cost.

The PIECAL 820 multifunction process calibrator ships complete with:

  • Test Leads (3' long with retractable shield banana plug & alligator clips)
  • RTD Wire Kit (2 Red & 2 Black Leads with Retractable Shield Banana Plugs & Spade Lugs)
  • Protective Rubber Boot
  • Certificate of Calibration
  • Carrying Case
  • Four "AA" Alkaline batteries
