Multifunction Bench Calibrator | Martel 3001

Supplier: Zedflo Australia

The Martel Multifunction Calibrator combines the power and features of a voltage/current calibrator, with the addition of thermocouple, RTD and pressure calibration, for a single laboratory calibration instrument unmatched in versatility, performance and value.


The calibration equipment's world class performance and features are accessed through a very simple to use, intuitive user interface.

The 3001 calibrator is an accurate full-featured temperature, pressure and DC calibrator intended for R&D, manufacturing and calibration lab applications.

The unit's simple design and ease of operation allow users to quickly familiarise themselves with its operations and features.

Time saving functions like the ability to save, recall and automatically cycle through set-points for each output range, the ability to enter user definable RTD curves, and a complete remote interface are several key features offered by the 3001.

Simple, intuitive interface

The 3001 calibrator provides simple, front-panel entry of mode, range, and value, using either direct keyboard entry or cursor entry. In the voltage output mode, the 3001 auto-ranges on the entered value for maximum accuracy at all times.

The performance you demand – in any mode

In Thermocouple Mode, the Martel 3001 can read and source any of 11 types of thermocouples. It's Thermocouple input and output is Cold Junction Compensated, using an ultra-stable PT-1000 sensor.

RTD mode:

The 3001 can read and source 9 RTD types as well as YSI 400 Series Thermistors and Ohms for non-standard curves.

Probe coefficients (A, B, C, and R0) can be entered directly, with storage for up to five custom curves and one SPRT curve. The performance of the 3001 in the RTD mode compares to dedicated RTD measurement instruments.

Unlike low-cost, less accurate RTD instruments, the display in the 3001 is always active, reading to three decimal places, using polynomial averaging to extract a high accuracy signal. The result is a very quiet, high accuracy reading.

Voltage mode:

The 3001 offers four precision voltage output ranges (100mV, 1V, 10V, and 100V) all with 0.003% (30ppm) accuracy.

These ranges are ideal for calibrating a broad range of DC voltage instrumentation. Additionally all voltage outputs settle to full specification in less than 200ms making the 3001 ideal for automated calibration systems.

An automatic stand-by mode assures that output voltages above 30VDC must be acknowledged by the operator before the voltage appears at the output jacks. The stand-by mode is also triggered if the output current compliance is exceeded, thereby protecting the device under calibration.

Current mode:

The 3001 features a precision current output range (100mA) that offers 0.01% (100ppm) accuracy, which is ideal for calibrating process instrumentation especially 4 to 20mA equipment.

With a full 12 volts of compliance at 100mA virtually any precision DC current measuring device can be calibrated using the 3001. Like the voltage ranges, the current range offers quick settling time and an operate/stand-by mode.
