Who Uses This HKC-30 Soil Speedy Moisture Tester Apparatus
A wide community of professionals across Bangladesh actively uses the HKC-30 Soil Speedy Moisture Tester Apparatus in their daily work.
Civil Engineers & Site Supervisors
Civil engineers carry this tester on road, bridge, and building construction sites to run rapid moisture checks before compaction. Site supervisors rely on it to approve earthworks without waiting for laboratory reports.
Geotechnical Consultants
Geotechnical consultants use the apparatus during soil investigation campaigns to record in-situ moisture profiles alongside other borehole data. The rapid result supports immediate field decisions.
Government & LGED Engineers
Engineers at LGED, BWDB, RHD, and other government bodies use the HKC-30 to enforce soil quality standards on public infrastructure projects throughout Bangladesh.
Soil Testing Laboratories
Accredited labs keep the HKC-30 as a rapid-check instrument alongside oven-drying setups. It handles overflow during peak testing seasons and serves as a field verification tool.
Agricultural Extension Officers
Agricultural extension officers and researchers use the tester to monitor crop land soil moisture content and advise farmers on optimal irrigation timings.
Frequently Asked Questions (FAQ) HKC-30 Soil Speedy Moisture Tester Apparatus
1. What does the HKC-30 Soil Speedy Moisture Tester Apparatus measure?
The HKC-30 measures the moisture content of soil and similar granular materials as a percentage of the total wet weight. It uses the calcium carbide pressure method to produce results within 5 minutes.
2. How does the calcium carbide method work?
The operator places a weighed soil sample and a calcium carbide reagent capsule inside the sealed pressure vessel. The calcium carbide reacts with the moisture in the soil to release acetylene gas. The resulting gas pressure drives the dial gauge needle to indicate the moisture percentage directly.
3. Does the HKC-30 require electricity or battery power?
No. The HKC-30 operates entirely on the chemical reaction inside the sealed vessel. It requires no electricity, no batteries, and no external power source, which makes it perfectly suited for remote field sites.
4. What is the accuracy of the HKC-30 moisture reading?
The HKC-30 delivers measurement accuracy of ±0.5% moisture content. This level of accuracy satisfies the requirements of ASTM D4944 and BS 1377 Part 2 standards for field moisture testing.
5. How much soil sample does each test require?
The required sample weight depends on the expected moisture range. Operators typically use 6 g for high-moisture soils, 10 g for medium-moisture soils, and 20 g for low-moisture soils. The instrument manual provides a full sample weight chart.
6. Where can I buy calcium carbide refill capsules in Bangladesh?
ASTZ Bangladesh stocks calcium carbide reagent capsules compatible with the HKC-30 and all standard speedy moisture testers. You can order refills through our website, by phone, or at our Dhaka showroom.
7. Does the HKC-30 comply with international testing standards?
Yes. The HKC-30 method conforms to ASTM D4944 (Standard Test Method for Field Determination of Water Content of Soil by the Calcium Carbide Gas Pressure Tester) and BS 1377 Part 2.
8. Can I use this tester for materials other than soil?
Yes. The HKC-30 also tests moisture content in sand, gravel, crushed aggregate, and some construction materials like lime and fly ash. The operator must use the correct sample weight table for each material type.
9. How do I clean and maintain the HKC-30 after use?
After every test, the operator opens the vessel, removes residual soil, and cleans all internal surfaces with the included brush and cleaning rod. The O-ring seal requires periodic inspection and light greasing to maintain an airtight fit.
