ThermoWorks 9150-X HART SCIENTIFIC 9150 THERMOCOUPLE FURNACE - Manual (Page 11)

2 Introduction
The Hart Scientific 9150 thermocouple furnace can be used for calibrating ther-
mocouple and RTD temperature probes. Calibrations may be done over a range
of 150°C to 1200°C (302°F to 2192°F). Temperature display of the 9150 is 0.1
degrees below 1000°and 1 degrees above 1000°.
The furnace features:
• Rapid heating and cooling
• Interchangeable multiple hole probe sleeves
• Convenient handle
• RS-232 interface
Built in programmable features include:
• Temperature scan rate control
• Eight set-point memory
• Adjustable readout in °C or °F
The temperature is accurately controlled by Hart’s hybrid analog/digital con-
troller. The controller uses a Type S thermocouple as a sensor and controls the
well temperature with a solid state relay (triac) driven heater. The furnace
should be calibrated yearly by trained personnel at Hart Scientific.
The LED front panel continuously shows the current well temperature. The
temperature may be easily set with the control buttons to any desired tempera-
ture within the specified range. The calibrator’s multiple fault protection de-
vices insure user and instrument safety and protection.
The 9150 calibrator furnace was designed for portability, low cost, and ease of
operation. Through proper use, the instrument will provide continued accurate
calibration of temperature sensors and devices. The user should be familiar
with the safety guidelines and operating procedures of the furnace as described
in this manual.
