We are offering This heat flow meter is a commercial apparatus for thermal conductivity (or thermal resistance) of insulation materials by guarded hot-plate. Specification GUARDED HOT PLATE :- Size : Metering area :- 150 x 150 mm Guard : 75 mm all around with a gap of 3mm between guard and central. Overall size : 310 mm Plate thickness : 4 mm (approx). Material : brass Max. Working temperature: 150°C No. of thermocouples : 2 each in central & Guard plate. (One for control & 3 for monitoring) Central plate: 4 thermocouples are mounted on Central Plate (two at upper and lower side at the center) i.e. total 4 thermocouples. Guard plate: 4 thermocouples are mounted on Central Plate (two at upper and lower side at the center) i.e. total 4 thermocouples. COLD PLATES :- Overall Size : 310 x 310 mm Thickness : 1 mm (approx) Material : copper. No. of thermocouples : 4 in plate.(One for control & another for monitoring) Maximum working temperature : -20°C. Specimen dimensions A single specimen is required. Thickness: 30 mm to 75 mm(The thickness is within 2% of its mean thickness over its whole area) Note: Thinner specimens can be measured, if it is the thickness that they will be supplied to the end user Length and breadth: 310*310 mm (Within range 305 mm to 311 mm) Flatness: The 310 mm square faces are flat to better than 0.2 mm (Flatness criteria do not apply to compressible or fibrous insulations) Thermal conductivity range: up to 0.5 Wm·K Mean specimen temperature range: -20 to 150 c Confirms as per IS:3346
