DRE-2 A coefficient of thermal conductivity tester (transient double hotline method)
DRE-2 A coefficient of thermal conductivity test instrument used transient double hotline method, the main measure liquid coefficient of thermal conductivity, the temperature coefficient (thermal diffusion coefficient) and specific heat. Of measuring speed, YangPinLiang needed less, high precision, high resolution, high repetition, sex etc. Characteristics. Controlled by computer for automatic measurement. Widely used in petroleum, chemical, biological, pharmaceutical, energy, power engineering field working medium the thermal conductivity of the fluid measurements.
The main technical parameters:
(1) measurement range: 0.001 ~ 5.0 W / (m • K)
(2) temperature range: 40 ~ 120 ℃-(need to match the corresponding temperature sink or the oil)
(3) measurement accuracy: < plus or minus 3.0%
(4) of samples: < 80 ml
(5) the measuring time: ten (10) seconds
(6) pressure environment: optional vacuum or pressure system.
(7) the reference standard: ASTM D2717 95
(8) sample shape: liquid; Gas.
