New F201 3/4 wire PRT Precision Thermometer

New 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. Better yet, the ASL SMART connectors use the ASL standard 5-pin DIN connector, so you can use probes with normal, passive connectors on the same input. How's that for versatility.

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
