ThermoWorks 9009-B INDUSTRIAL DUAL-BLOCK CALIBRATOR - Manual (Page 14)

2 Introduction
The Hart Scientific 9009 Industrial Dual-Block Calibrator may be used as a
portable instrument or bench top temperature calibrator for calibrating thermo-
couple and RTD temperature probes. The 9009 is small enough to use in the
field, and accurate enough to use in the lab. Calibrations may be done over a
range of –15°C to 350°C (5°F to 622°F). Temperature display resolution of the
9009 is 0.1 degrees.
The dry-well calibrator features:
• Two independently controlled temperature blocks
• Rapid heating and cooling
• Interchangeable multiple hole probe sleeves
• Convenient integrated carrying case
• RS-232 interface
Built in programmable features include (applicable to both the hot and cold
blocks):
• Temperature scan rate control
• Eight set-point memory
• Adjustable readout in °C or °F
The temperature of each well is accurately controlled by a precision Hart Sci-
entific controller. The controller uses a precision platinum RTD as a sensor and
controls the hot temperature block with a solid state relay (triac) driven heater.
A thermal electric device (TED) controls the cold temperature block.
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.
Note: When one of the temperature blocks is being accessed through the front
panel, the other temperature block control panel is not accessible. Always press
the “EXIT” button to exit the control panel being used.
The 9009 calibrator was designed for portability, low cost, and ease of opera-
tion. Through proper use, the instrument will provide continued accurate cali-
bration of temperature sensors and devices. The user should be familiar with
the safety guidelines and operating procedures of the calibrator as described in
the instruction manual.
