RAPID MOISTURE METER AZA0874
The AZA0874 Rapid Moisture Meter from Azalab is a compact, reliable, and field-proven instrument designed for quick determination of moisture content in soils, aggregates, sand, and other granular or fine materials. It is especially suited for on-site quality control in civil engineering, road construction, earthwork compaction, and geotechnical investigations, where timely moisture data is critical for effective decision-making.
Based on the well-established calcium carbide gas pressure method, the AZA0874 delivers accurate results within minutes, eliminating delays associated with laboratory oven-drying methods. Its portable, self-contained design makes it ideal for use at remote and demanding job sites.
Description
Principle of Operation
The AZA0874 operates on a chemical reaction principle. When moisture present in the sample reacts with calcium carbide (CaCâ‚‚) inside a sealed pressure vessel, acetylene gas (Câ‚‚Hâ‚‚) is generated. The pressure produced is directly proportional to the moisture content of the sample.
A precision-calibrated pressure gauge mounted on the vessel directly indicates the moisture content as a percentage (wet weight basis). No external power source is required, making the instrument highly suitable for field conditions.

SEMI AUTOMATIC CONE PENETROMETER AZA0852
Principle of Operation
A soil paste prepared at known moisture content is placed in the sample cup. The standardized cone, attached to a calibrated weight, is released using the semi-automatic clutch mechanism, allowing free fall penetration into the soil. After the specified time (typically 5 seconds), the penetration depth is measured using a high-precision dial gauge. The moisture content corresponding to a penetration of 20 mm is considered the liquid limit of the soil, as defined in IS and BS standards.
