The Valhalla 4150ATC has a high gain pre-amp to provide higher resolution measurements with 100 times less power dissipation in the test time. The 4150ATC is ideal for testing thermistors, RTD's, strain gauges, Balco sensors, and other transducers where minimizing self heating is critical during product calibration. The 4150ATC is an excellent tool for component testing, matching and sorting of resistors, chokes, coils, transformers, heating elements, and plated thru holes.
