Temperature dependence of resistivity: R(T) = R0 x (1 + A x T + B x T2) A = 3.9083 x 10-3 °C-1 B = -5.775 x 10-7 °C-2 C = -4.183 x 10-12 °C-4 R0 = resistance value in Ω at T = 0 °C T = temperature in accordance with ITS90 Storage temperature: 2) Geometry of the containing chamber or vessel in the final application can affect the cell constant and measurement range. Please contact IST AG for more information. 3) Although operating temperature is under 100 °C, the device will temporally withstand higher temperatures. Contact IST AG for more information. 4) Self-heating must be considered....
