National Instruments High Precision Temperature and Voltage MeterUSED
NI 4350
The NI 4350 features accurate thermocouple and DC voltage measurements. You can also take temperature measurements with resistance temperature detectors (RTDs), thermistors, ohm measurements using the built-in precision current sources, and current measurements using external shunt resistors. You can use the NI 4350with a personal computer to make the same measurements you would with standard bench-top instruments such as data loggers and DMMs. The NI 4350 contains a 24-bit sigma-delta analog-to-digital converter (ADC) with differential analog inputs. The low leakage construction, along with analog and digital filtering, provides excellentresolution, accuracy, and noise rejection. With software-programmable ground-referencing, you can reference your floating signal without compromising voltage measurements even if the floating signal is, in fact, ground-referenced. With software-programmable open-thermocouple detection, you can quickly detect a thermocouple that may have broken before or during measurement. You can measure up to a total resistance of 600 kW using the built-in25 mA precision current source on the NI 4350.
