TIR 100-2 Measuring of thermal emissivities within seconds TIR100-2 is a compact hand-held unit to measure thermal emissivity of nearly any surfaces precise and nondestructive. Measuring elements, operation control, control device, and evaluation electronics as well were placed space saving in the hand-held unit. Instrument operation requires only a power supply. Operation of the device happens by a great illuminated touch screen display. Function: Object surface is diffuse irradiated with a 100° C half sphere shaped black body radiator. The reflected infrared radiation is measured and converted into an absolute value of emis- sivity by the help of the calibration values of the calibration standard belonging to the in- strument. The result is displayed immediately on the touch screen of the device. A detailed instruction manual informs about the physical basics of the measurement proce- dure and the handling for precise measuring.
TIR 100-2 Measuring of thermal emissivities within seconds
TIR100-2 is a compact hand-held unit to measure thermal
emissivity of nearly any surfaces precise and nondestructive.
Measuring elements, operation control, control device, and
evaluation electronics as well were placed space saving in the
hand-held unit. Instrument operation requires only a power supply.
Operation of the device happens by a great illuminated touch screen
display.
Function: Object surface is diffuse irradiated with a 100 C half
sphere shaped black body radiator. The reflected infrared radiation
is measured and converted into an absolute value of emis-sivity by
the help of the calibration values of the calibration standard
belonging to the in-strument. The result is displayed immediately
on the touch screen of the device. A detailed instruction manual

emissive side >0,96 Ex works basis all references are
individually adjusted to a calibration standards of the National
Physical Laboratory, GB.
Applications The TIR100-2 may be used for quality control af-ter
a coating process or to assist research and development in
laboratory. Measurement result for glass is quite equal to results
after EN 12898. Emissivity of coated foils as construction foils is
measured after prEN 15976.
Some typical applications: Qualification of coated glass
Qualification of coated solar collector sheets Qualification of
coated foils Qualification of thermal coating of satellites
