ISOMET 2114 is a hand-held measuring instrument for direct measurement of heat transfer
properties of a wide range of isotropic materials including cellular insulating materials, plastics,
glasses and minerals. It is equipped with two types of measurement probes: needle probes for soft
materials, surface probes for hard materials. It applies a dynamic measurement method, which
enables reducing the measurement time in comparison with steady state measurement methods.
Built-in menu system on color graphic display and the alphanumeric keypad enable effective
interactive communication with the device. Measurement data are stored in the high capacity internal
memory. Content of the memory is accessible through the display or it can be transferred into a PC
by USB or RS-232 interface. Calibration data in internal memory ensure interchangeability of probes
without affecting the measurement accuracy. Since supplied measurement probes have good long
term stability through the whole measurement range, periodic calibration before measurements is not
necessary. Nevertheless, calibration by means of a reference material is supported by the instrument.
Calibration coefficient stated in the sense of the standard ASTM
– 5334-08 may be applied to
subsequent measurements automatically.
ISOMET2114 is powered by internal rechargeable batteries, which makes outdoor, in situ
measurements easier.
