Orbit Research Associates Private Limited

LAMBDA is a compact, operator-friendly transient hot wire instrument that facilitates a fast determination of the thermal conductivity, thermal diffusivity and specific heat capacity in a wide temperature and pressure range by means of the transient hot wire (THW) method, according to ASTM D7896-19.
This highly accurate athermal calorimeter is suited for fluid analysis in the laboratory as well as in the field, including the measurement of thermal conductivity of nanoparticle dispersions/nano fluids.
Our LAMBDA Thermal Conductivity Meter can be operated either in stand-alone mode or with the intuitive software (incl.) on your WINDOWS computer via RS-232/USB.
