PRS-330 Precision Programmable Resistance Box & RTD Simulator

The PRS-330 is the decade resistor you need for calibration labs and automated production environments

Very tight accuracy, almost no long term maintenance costs

  • Resistance range: 0.1 Ω to 20 MΩ with a Resolution of 1 μΩ or 6 digits
  • Lab grade accuracy (70 ppm + 1 mΩ): 1.5 times better than conventual manual decade resistors
  • Large color touchscreen, soft keys and intuitive interface promotes little to no training
  • Can be used as both a Manual or an Programmable unit in both calibration lab and production environments.
  • Comes standard with USB, Ethernet and IEEE interfaces and full LabView command structure, see manual and drivers for more details
  • If you do NOT own an 8.5 Digit DMM (Fluke 8508A or Keysight 3458) OR if you require an Ethernet or USB Interface this is the instrument for you

  • Virtually no maintenance cost, very simple to calibrate. If it drifts, it easily adjusts back to spec without costly repairs
  • High reliability relays, rated for 100 Million Switches
  • Rated for use at 0.5 W, for higher power consider the PRS-202
  • Use for RTD applications is straightforward with built-in PT-100 and PT-1000 Tables, RTD values can be input in both °C, °F
  • Strong ac performance
  • No zero or switch resistance 0.1 Ω is 0.1 Ω
  • Front and rear binding posts for ease of connection
  • Sold with an industry leading 5 year warranty and Manufactured in the USA
  • About 10% lower in cost than the PRS-370 or its predecessor unit the PRS-300
  • If you already own, or are considering buying, an 8.5 Digit DMM you should strongly consider the PRS-370 instead of the 330
