Description

The 2560A precision DC calibrator is an accurate and low cost calibrator that can output DC voltage over 1200 V and DC current over 36 A alone. In addition to being able to calibrate analog meters, the 2560A can calibrate thermometers and temperature controllers that utilize a thermocouple or RTD. The 2560A is known for it’s high accuracy, stability and ease of use. A dedicated output setting dial for each digit in the numeric display, and a dial for selecting voltage output, current output, temperature calibration, and other functions make calibration quick and efficient. The 2560A supports various communication interfaces (GPIB, USB, and Ethernet) making the transferring of data a breeze.
The 2560A can calibrate many different types of thermometers and temperature controllers and is compatible for use with all 10 thermocouple types as well as the platinum 100 (pt100) RTD specified by the International Electro technical Commission (IEC).

IIII [+] Read More
The 2560A offers high voltage and high current generation and intuitive operation for the analog meters calibration. With output ranges of 100 mV to 1000 V and 100 µA to 30A, plus 10 different types of Thermocouples and Pt100 RTD, allows the 2560A to effectively solve the calibration requirements for DC Analog Meters and various temperature measuring instruments and controllers.
