Version C


Real Measurement Range is the Thermal
Transmittance Resistance of the inserted sample (correlated with the measurement of the electrical heating power of the measuring heater):

R =0.1 ... 14 m²K/WR = 0.025 ... 14 m²K/W

corresponding Thermal Conductivity (ca.):

λ = 0 ... 0.5 W/(m·K)λ = 0 ... 3 W/(m·K)

Measuring Area/Zone:

200 x 200 mm²150 x 150 mm²

Sample Thickness:

10 ... 120 mm
(optional 4 ... 200 mm)

Sample Dimensions:
  • optimal 500 x 500 mm²
  • other dimensions: 400 x 200 mm², 300 x 300 mm², 420 x 370 mm², etc.
  • also one side loner, e.g.: 1000 x 500 mm²
  • minimal: Measuring Area/Zone
    ---> can be easily automated!

Reproducibility:

< 0.5 % (mostly < 0,2 %)

Accuracy:

< 1.0 % (mostly < 0,7 %)

Measurement Temperature Range (Standard):

10 ... 40 °C
(optional -10 ... 50 °C)

Temperature Difference Range (Standard):

5 ... 15 K
(optional 20 K)
