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

 

The PRS-330 was designed with the right mix of features for to be efficient for both manual and automated application in both laboratory and production environments such as; calibration of resistance meters, calibration of temperature controllers and indicators, automated test systems requiring a precision resistive load.

With its wide resistance range and 6 digit resolution, the PRS-330 was designed to replace multiple decade boxes and reduce test time.

With its industry leading 5-year warranty all aspects of the PRS-330 focus on reliability, reduced ownership costs and simplicity out of the box.

• 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 perfomance
• 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
