Novelty: an automatic portable and digital measuring instrument destined for successive calcium carbonate measurements in up to six soil samples is disclosed. Constitution: a portable digital analyzer with incorporated communication and geographical position location unit (GPS) (A), a digital screen LCD (B), a multi-sensor (&Ggr;) for pressure and temperature measurement, control buttons (&Dgr;), a micro-processor (E), a flexible polyurethane tube (Z), a plastic screwable cap with hole wherethrough the tube is passing, a glass reaction head into which the sample with the hydrochloric acid reacts (Θ), a vial receiving the hydrochloric acid reagent (I), and batteries (K). Advantage: synchronical pressure and temperature measurement by use of the multi-sensor provided; high-accuracy measurements due to the automatic temperature counterbalancing means; potential communication and location of the geographical position; data storage on a specific memory, specifically when the invented instrument is used in the field; high productivity in short time due to the plural heads (up to six) destined for the successive measurement of six soil samples. |
