Keithley Integra Bench Digital Multimeter True RMS 3 A AC, 3 A DC, 750 V AC 2750/E

Keithley 2750/E Integra Bench Digital Multimeter True RMS is a high-precision benchtop multimeter designed for accurate measurement of electrical parameters including DC and AC currents up to 3 A, and voltages up to 750 V AC. It combines the functions of a digital multimeter, switch system, and data logger in one integrated enclosure with 5 slots for modular plug-in expansions.

This instrument features a true 6½-digit (22-bit) resolution providing exceptional accuracy with DC current accuracy of ±0.05% reading plus 8 digits and DC voltage accuracy of ±0.003% reading plus 3.5 digits. It measures resistance with 1μΩ resolution and temperature via thermocouples, RTDs, or thermistors. Maximum frequency supported is 440 Hz.

Equipped with Ethernet and RS-232 interfaces, the 2750/E model facilitates high-speed and long-distance communication with computers and networked instruments. The device supports up to 200 differential input channels with 300 V isolation enhancing safety in demanding environments.

The modular architecture allows configuring the system with twelve different switch/control plug-in modules, enabling users to expand measurement capabilities as testing needs evolve. The compact benchtop form factor with dimensions of 238 mm length and 104 mm height ensures easy integration in laboratory or industrial racks.

6½-digit true resolution enhances measurement accuracy. Flexible 2- or 4-wire resistance measurement with offset compensation. Wide voltage and current measurement ranges including 1 kV DC max voltage. Integrated data acquisition and control systems reduce rack space requirements.

Lithium battery provides 3 years of operation ensuring reliability. Operating temperature range from 0°C to 50°C suits varied environments. Supports frequency and continuity measurement for comprehensive testing. Compatible with ExceLINX datalogging software for efficient data handling.
