The Model 195T is an enhanced version of the Model 195 that includes temperature measuring capabilities. The Model 195T is capable of temperature measurements in the range of -220°C and + 630°C and between -360°F and +1100°F. The instrument is designed to work with platinum RTD probes, a factor which contributes to high accuracy. Temperature readings may be read directly from the front panel display or transmitted over the IEEE bus to a central controller or other instrumentation. Some key Model 195T features include: 1. High Accuracy. Because platinum RTD probes have predictable resistance change with temperature and are highly linear, temperature measurements are made with a greater degree of accuracy than is possible with thermistor or thermocouple type probes. 2. Ease of Use. The temperature measuring mode is easily entered from the front panel or over the IEEE bus. Sophisticated software automatically measures the probe resistance and calculates the reading. 3. Dual Scale Temperature Measurements. Temperature readout may be obtained in either °C or °F. Readings are available on the display and over the IEEE bus. 4. Front Panel Calibration. Temperature calibration may be performed from the front panel. Probe errors can be minimized with the calibration procedure. 5. Four Wire Resistance Measurements. Resistance measurements with the supplied probe are performed using the 4-wire method to minimize the effects of lead resistance. 6. Selectable 3-wire or 4-wire Operation. The instrument may be used with either 3-wire or 4-wire probes; the mode of operation is easily changed from the front panel.
