• Rotronic Instruments GTS-SET Equilibrium Relative Humidity Probe Set. The Rotronic GTS-SET is an instrument set for the measurement of equilibrium relative humidity and temperature in stacks of paper and cardboard. It consists of a flat blade probe that can be easily inserted into a stack of paper, cardboard or textiles. The temperature and humidity within the stack can be read off the LCD display on the unit. Integrated 200mm aluminium sword probe for equilibrium humidity and temperature measurement. Sturdy, very robust mechanical components. Display of equilibrium humidity or temperature via LCD panel. Easy operation by push button. Adjustment by potentiometer. Measurement ranges: -10 to +60°C / 0 to 100 %RH. Display resolution: 0.1 %RH / 0.1 °C. Battery operation (1 x PP9 9V, included). Low battery indicator. Display hold and auto power-off functions. Set consists of:. GTS handheld instrument with 200mm sword probe. Calibration service: EGS. SCS calibration standard EA50-SC5 (5 ampoules, 50%RH with SCS certificate. Adjustment screwdriver. Carry case: AC1102. What is equilibrium relative humidity (ERH)?. Moisture migration from a material into the atmosphere and vice versa continues until stabilisation of the vapour pressures of water (inside the material and in the atmosphere). When this equilibrium is reached, the moisture content of a material can be expressed in Equilibrium Relative Humidity (ERH).
