<p>Automatic portable and digital soil calcimeter with one or more places for sequentially measurement of up to six samples that consists of the following parts: A portable digital analyzer with a built-in unit for communication and determining the geographical position (GPS)(A), A liquid crystal display (B), A multi-sensor for precision measurement of pressure and temperature (C), Control keys (D), A microprocessor (E), A flexible polyurethane tube (G), A plastic screw cap with a hole through which pass tubes (H), A glass reaction vessel into which the sample reacts with hydrochloric acid (I), A reagent receiving vial containing hydrochloric acid (J), Rechargeable batteries (F). The major advantage of this invention is the use of a multi-sensor, which combines simultaneous measurement of pressure and temperature. In addition to the measurement of temperature, the instrument has a built-in module for automatic temperature compensation, in order to perform measurements with higher accuracy. Other important advantages of the instrument are its ability to communicate and tracking the geographical location (GPS) and save this in a special memory, especially for field measurements. In addition, the portable instrument can host up to six heads for sequentially measurement of six samples providing to the end-user the advantage of high productivity.</p> |
