This infrared thermocouple
system consists of a standard Series 12 infrared source, a
Type K thermocouple and an optional digital thermometer.
These units have been used as checks on infrared
instruments such as thermometers and cameras. When power is applied to the
infrared source the unit heats and the digital thermometer generates a digital
read out of the surface temperature (see note below). The thermocouple output
can also be used as an input to the power supply system to control the source
Infrared Source IR-12K/TC
The Type K thermocouple
sensor is fabricated using special limit error thermocouple wire. The wire is
rated at ±1.1°C. However the thermal connection between the
thermocouple and the IR source isn't perfect and the reading from the
thermocouple can be between 50 and 100°C lower. E.g. If the source is
operating at 975°C, the thermocouple will read between 875 and 925°C.
The thermocouple cannot therefore be used to measure the temperature of a
source but is useful for tracking the thermal stability of a source.
The sensor is applied directly to the coil of the
infrared source. High temperature, low-expansion material is used to apply the
sensor. The thermocouple is terminated with a standard Type K ANSI miniature
Digital Thermometer /DT
The thermocouple system can be plugged directly into
this unit. The meter accepts all Type K thermocouple probes with ANSI
HOLD button to freeze reading
Switch for readouts in °F and °C
Display has large 1/2" digital characters
Measurement range: -50°C to 1300°C
Meter comes with 9 volt battery
Three and a half digits
Our MC-233 and MC-234 parabolic and elliptical
reflectors can be modified so that they can be used
with the thermocouple systems. Please contact us
