Technical Index measuring range of atmospheric pressure: 80 to 106 kPa Working temperature range: -10 ° C ~ + 40 ° C In the whole area the error does not exceed the barometer display 0.2 kPa. Throughout the range, the pointer returns the pressure to its original position according to increasing or decreasing. The error is not more than 0.25 kPa Select a scale interval of 0.1 kPa. The weight of the instrument must not exceed 1.5 kg. Instrument Size: 156 x 156 x 115 mm Terms of Service Installation: to erroneous readings due to avoid inclinations of the instrument must be horizontally placed. use: Please note when measuring pressure and temperature the following: (1) Click to eliminate the reading on the instrument housing to the friction in the rotation mechanism. (2) The line of sight of the observer must be perpendicular to the scale plane. (3) The air pressure must be read at the next location of the pitch value. (4) The pressure must not exceed 106 kPa. If the glass is broken. Please note: The device must be stored in a ventilated, non-corrosive gas space
