INTRODUCTION
Nagman’s Universal Dry Block High Temperature
Calibrator is used for calibrating RTD’s,
Thermocouples, Temperature Switches, Temperature
Indicators etc.
The front panel continuously shows the current
Thermowell block temperature. Desired temperature
is set by using keypad which gives the corresponding
set value in the display.
Proper use of the instrument will provide accurate
calibration of temperature sensors.
Heater Block
The “Block” is made up of Inconel and provides a
relatively constant and accurate temperature
environment.
A thermo well is provided that may be used for
sensors of that size or may be sleeved down with
various sized multi-hole probe sleeves.
Heaters embedded in the block assembly provide
uniform heat to the sensor. A high temperature
platinum RTD is embedded at the base of the block
assembly to sense and control the temperature of
the block.
The entire assembly is suspended in an air cooled
chamber thermally isolated from the chassis and
electronics.
