Introduction

In automated production environments, test speed and accuracy are critical. PXI-based digital multimeters (DMMs) combine precision measurements with high-throughput integration capabilities, making them ideal for in-line and end-of-line functional testing. Below are the best PXI multimeters available in 2025, selected for speed, resolution, and seamless PXI platform integration.

Top PXI Multimeter Models in 2025

1. NI PXIe-4081 – 7½ Digit Precision DMM

The PXIe-4081 is one of the most accurate PXI DMMs on the market, offering ±100 nV sensitivity and 7½ digit resolution. It supports DC/AC voltage, current, resistance, diode, and capacitance measurements, with 1,000 readings/sec throughput.

2. NI PXI-4071 – High-Resolution 6½ Digit DMM

The PXI-4071 is a proven workhorse for production testing. With a sample rate of up to 10 kS/s and excellent noise immunity, it remains a favorite for tight tolerance environments.

5. ADLINK PXI-2010 – Cost-Effective Production DMM

A solid entry-level PXI multimeter with basic 5½ digit performance and integration into hybrid test benches. Ideal for budget-conscious high-volume setups.

Key Selection Criteria

• Measurement Speed: Look for ≥1000 readings/sec for high-throughput.
• Resolution: 6½ to 7½ digits depending on product tolerance requirements.
• Integration: Must support trigger bus and synchronization with PXI chassis.
• Thermal Stability: For round-the-clock test lines.

Frequently Asked Questions

Why use a PXI DMM instead of a benchtop one?

PXI DMMs integrate into automated test systems, offer faster throughput, and reduce test floor space.

Which PXI DMM is best for 24/7 production testing?

The NI PXIe-4081 offers excellent long-term accuracy and thermal stability.

Can PXI DMMs measure current directly?

Yes, most models offer DC/AC current ranges with high precision and internal shunt resistors.
