Avaibility: AVAILABLE

Call For Price

The Martel Electronics IVC-222HPII Voltage/Current Calibrator is a general purpose current and voltage source that can be
used in engineering, manufacturing, test, and process control applications. It combines both digital and analog circuitry to
achieve its rated specifications in a small, reliable package.

The IVC-222HPII has the capability to store and recall up to two setpoint values, the SP1 and SP2 keys. An
RS-232 port accessed via a custom cable (available from Martel) allows the calibrator to be computer
controlled for automated testing.

General Features:

  • Remarkable 0.015% of reading accuracy
  • Four ranges: 200 mV, 2 V, 20 V and 24mA
  • Intuitive, easy-to-use controls . RS-232 interface allows computer control
  • Built-in 24 V supply can drive 4 to 20 mA loops over 1,000 Ohms
  • Rugged, lightweight, hand-held unit
  • Includes test leads, carrying case, 9 V battery, NIST
  • Full rubber boot with optional carrying case
  • Certificate, and instruction manual
