Martel Electronics 3001

Martel Electronics 3001 Precision Lab Standard Calibrator.

The Martel Electronics 3001 is a high-precision lab standard calibrator engineered for demanding calibration environments where accuracy, reliability, and flexibility are critical. With an accuracy of up to ±0.0025% of reading and a fully isolated readback channel, this calibrator is ideal for sourcing and measuring voltage, current, resistance, RTDs, thermocouples, and pressure (read-only).

Designed for both benchtop and rack use, the 3001 supports digital and rotary control, as well as full remote control via RS232, USB, and IEEE-488 interfaces. It is compatible with Fluke Met/Cal and supports popular pressure modules including Fluke 700 series, BetaPort, and Mensor 6100 Series.
