The NEW F200 series 3/4 wire PRT PrecisionThermometers comprises of two models: Model F200 accepts 4 wire PRTs Model F201 accepts both 3 & 4 wire PRTs High Performance 2 or 8 channel, 3 and 4 wire Precision Digital Thermometers for use with calibrated and uncalibrated Pt100 probes, with great new features for increased usability and lower life-costs. Using calibrated probes with the F200 thermometer series you choose between storing calibration data into memory in the instrument or into the probe’s proprietary “SMART” connector. Calibration data stays permanently with the probe in this connector, which the F200 series instantly recognizes, ensuring best measurement accuracy. Calibration Using a built-in calibration routine, the operator can re-calibrate the F200 instrument range using a calibrated, traceable reference resistor. This feature is password protected. Other features have been included for F200 range when using SMART probes, like the Temperature Watchdog and the Calibration Status Monitor. The Temperature Watchdog, continuously monitors the temperature of SMART probes and, if any are used outside their specified working range, the probe history record is updated. This way you can see at a glance if your probes have ever been used outside their calibrated range, as this may affect their calibration validity. The Calibration Status monitor alerts you with an on-screen message when a SMART probe is due for recalibration. Applications The F200 series is used in a variety of industries and applications where precision combined with portability is required. Where temperature profiling, calibration or validation is required the F200 series 3/4 PRT models may provide the solution that you are looking for.
