ALMEMO® measuring system for calibrating climatic chambers • As per guideline DAkkS-DKD-R 5-7 • Calibration of relative atmospheric humidity at nine points in the climatic chamber • Comprising data logger ALMEMO® 710, one humidity sensor, and eight temperature sensors Calibration of relative atmospheric humidity at nine points in the climatic chamber using precision measuring instrument ALMEMO® 710 The ALMEMO® measuring system, comprising precision measuring instrument ALMEMO® 710, one humidity sensor, and eight temperature sensors, can be used to acquire all relevant measurable variables prevalent in the climatic chamber. The relative atmospheric humidity at the nine points in the climatic chamber is calculated in the ALMEMO® 710 itself. Climatic chambers can thus be calibrated in full and on site quickly and easily. Humidity is calculated in the ALMEMO® 710 on the basis of formulae as per Dr. Sonntag and the enhancement factor as per W. Bögel (correction factor Fw(t,p)) for real mixed gas systems). This substantially widens the measuring range and improves the accuracy of humidity variable calculations. All values, both measured and calculated, are shown in a clear and easy-to-understand way on the ALMEMO® 710‘s large touch display. The ALMEMO® 710 also operates as a data logger. Measuring series can be saved either to the internal memory (capacity for over 400,000 measured values) or via the ALMEMO® memory connector to an SD card (capacity for several millions of measured values).
