1.  Heat Flow Meter


The Holometrix Rapid-K is constructed to conform to the requirements of ASTM C-518.
The heat flow meter's primary applications are the testing of coarse grain and non-homogeneous materials,
where the large sample is necessary in order to obtain test results that are representatuve of the sample material in bulk form.

Specifications:

Sample geometry	square
Sample size	12" x 12", 0.2" to 4" thick 30cm x 30cm, 0.5 to 10cm thick
Thermal conductivity range	0.1 to 3.0 BTU-in/hr-ft^2-°F 0.015 to 0.43 W/m°K
Mean sample temperature range	23 to 212 °F -5 to 100 °C
Repeatability	± 1%
Accuracy	± 5%

We operate the instrument using the Thermatest software supplied by Holometrix.
The instrument is regularly calibrated using NIST SRM 1450b fibrous glass standard.



2.  Guarded Hot Plate


The Holometrix GHP-300 is constructed to conform to the requirements of ASTM C-177.
The guarded hot plate technique is particularly suitable to inhomogeneous materials, due to the large sample size.

Typical materials tested in this instrument include:

• cellular plastic
• cellular glass
• fiber glass
• mineral fiber
• cellulose insulations
• textiles
• wood
• concrete, insulating concrete
• polymers
• filled plastics

Specifications:

Sample geometry	square
Sample size	12" x 12", up to 3" thick 30cm x 30cm, up to 7.5cm thick
Thermal conductivity range	0.05 to 14.0 BTU-in/hr-ft^2-°F 0.007 to 2.0 W/m°K
Mean sample temperature range	32 to 400 °F 0 to 200 °C
Repeatability	± 1%
Accuracy	± 4%

We operate the instrument using the Thermatest software supplied by Holometrix.
The instrument is regularly calibrated using NIST SRM 1450b fibrous glass standard.
