Temperature range -50 to +150 degrees Celsius with the external sensor 3½mm connector integrated Air temperature range through internal sensor -10 bis +50 degrees Celsius Humidity range 5% to 99% RH Tolerance +/- 2% Temp Tolerance +/- 0.3 degrees Celsius Automatic Dewpoint calculation Multilingual display Auto Power Off Scales : - Concrete (0-6% H20) - Cement Screed (0-6% H20) - Cement Screed (0-4% CM) - Anhydrite Screed (0-3.5% H20) - Anhydrite Screed (0-1.9% CM) - Caisson 0.3 - 15.3 Scale (0.3-15.3m) - Relative Scale (0-100%) VI-D4 Instruction.png General Functions : VI-D4 meter calculates humidity of analyzed material by measuring its electrical impedance. The relation between humidity of crtain material and its impedance is directly proportional. Impedance is measured through generating low frequency electric field between electrodes. The meter measures low intensity alternating current flowing through electric field and on that basis calculates moisture of tested material.
