2 Introduction 2 Introduction The Hart Scientific Model 9105/9107 dry-well calibrator may be used as a por - table instrument for calibration of temperature probes. The 9105 operates over the range of –25°C and 140°C. The 9107 operates over the range of –45°C to 140°C. These dry-well calibrators feature an interchangeable aluminum probe sleeve along with 4 fixed wells. The temperature is accurately controlled by Hart's precision temperature controller. The calibrator controller uses a precision
