Hot Disk Thermal Constant analyser TPS 500

The Hot Disk TPS 500 Thermal Constants Analyser rapidly and accurately measures thermal conductivity, thermal diffusivity and specific heat capacity of a wide range of materials. The TPS 500 measures the thermal transport properties of solids, pastes, gels and powders and encompasses similar accuracy and sample size flexibility as the benchmark TPS 2500 S and workhorse TPS 1500.

Guarded Hot Box

The Guarded Hot Box is used to measure the steady state thermal performance of building elements. In simpler terms, this means that the GHB measures the U-value of the specimen.

The U-value of material is the amount of heat transmitted through a material per unit area, per unit of temperature difference across it.

Solar Monitoring System

The Solar Monitoring System contains a pyranometer, a pyrheliometer and sun-tracking system. It measures the direct irradiance of the sun, and the diffuse irradiance of the sky. Using these recorded parameters, and empirical model of sky brightness can be computed for the Indian sky.
