  • Page 15: Introduction

    The Hart Scientific 9103 Dry-well may be used as a portable instrument or bench top temperature calibrator for calibration thermocouples and RTD tem- perature probes. The 9103 is small enough to use in the field and accurate enough to use in the lab. With an ambient temperature of 23°C (74°F), calibra- tions may be done over a range of –25°C to 140°C (–13°F to 284°F).
