Gould Bass DTM-25A Digital Test Meter & Shunt Kit



Gould-Bass DTM-25A Digital Magnetic Particle Test Meters measure the magnetizing current output of magnetic particle inspection machines. The DTM-25A is able to measure up to 12,000 amperes in AC, HWDC, and FWDC current outputs. Further selection can be made in the AC mode to read RMS or average value. This portable calibration kit contains both a 1,000 ampere 25mv shunt and a 1,000 ampere 50mv shunt. All components are contained in a rigid heavy duty metal carrying case.

The DTM-25A Meters contain their own high-speed current sampling circuitry in order to accurately sample and display current values directly from its shunt in the nominal 0.5 second shot. Digital Magnetic Particle Test Meters have an accuracy within +1% and continue to display the current output until the next magnetizing shot, which enhances calibration accuracy and speed.

The standard model comes in 115 Volts/60 Hz. The Model DTM-25A can also be ordered in 220V/50Hz/60Hz.
