Soil Hydrometer Price in Bangladesh 2026

If you’re comparing Soil Hydrometer price in Bangladesh, you’ll find options ranging from ৳250 for basic models to ৳1,400 for ASTM-grade instruments built for professional soil testing. Whether you’re a civil engineer running a sedimentation analysis or a student handling a lab assignment, picking the right hydrometer depends on your testing standard, budget, and required accuracy. This guide breaks down every model ASTZ currently stocks, so you can choose without guesswork.

What Is a Soil Hydrometer and Why Is It Used?

A soil hydrometer measures the density of a soil-water suspension to determine how particles of different sizes settle over time. Engineers rely on this data to classify soil texture — separating silt, clay, and fine sand fractions that sieve tests can’t isolate.

Sedimentation Analysis and Particle Size Distribution

The test works on Stokes’ Law: heavier, coarser particles settle faster than fine ones. By reading the hydrometer at fixed time intervals, technicians plot a particle size distribution curve. This curve is a standard requirement in geotechnical reports for foundation design, road sub-base evaluation, and agricultural soil classification.

ASTZBD Soil Hydrometer Models — Which One Is Right for You?

Hydrometer 1000-2000 (India) — Budget Option

At ৳250, this is the entry point for basic density readings. It suits general lab exercises, quick field checks, and buyers who don’t need certified ASTM traceability. Not recommended where a client or regulatory report demands standard compliance.

Hydrometer for Soil Test — Mid-Range Best Seller

Priced at ৳1,200, this is ASTZ’s most-ordered soil hydrometer. It’s built for routine sedimentation testing in labs that need consistent, repeatable readings without the premium cost of a fully certified instrument. (If this model carries ASTM 152H certification or a Bouyoucos scale, let me know and I’ll add that spec — it’s a strong trust signal worth highlighting.)

Hydrometer Test of Soil — ASTM Grade

At ৳1,400, this is the standard-compliant choice for consultants and testing labs that must submit results against ASTM specifications. It’s the model to recommend when a client explicitly asks for certified equipment.

Key Features & Technical Specifications

(Specific scale increments and calibration temperature should be confirmed from the manufacturer datasheet before publishing, to avoid listing unverified numbers.)

Soil Hydrometer Test — Step-by-Step Procedure

1. Take an oven-dried, sieved soil sample and mix it with a dispersing agent.
2. Add the suspension to a 1000 mL sedimentation cylinder and fill to the mark with distilled water.
3. Shake thoroughly, then place the cylinder upright and start the timer immediately.
4. Insert the hydrometer gently and take readings at 30 seconds, 1, 2, 4, 8, 15, 30, 60 minutes, and so on up to 24 hours.
5. Record temperature at each reading and apply correction factors.
6. Use the readings to calculate percentage finer and plot the particle size distribution curve.

Doing this correctly the first time avoids re-testing, which is where a reliable hydrometer pays for itself.

Buying Guide — How to Choose the Right Soil Hydrometer

Selection by Range

Match the hydrometer’s density range to the soil types you test most. A general lab handling mixed samples benefits from the 1000-2000 range; specialized geotechnical work may need a narrower, more sensitive range.

ASTM vs Local Standard Compliance

If your reports go to government agencies like LGED or RHD, or need BUET lab validation, an ASTM-grade hydrometer isn’t optional — it’s the difference between an accepted report and a rejected one.

Budget vs Precision Grade

For students and one-off checks, the budget model is fine. For commercial testing labs charging clients, the cost difference between ৳250 and ৳1,400 is negligible next to the risk of inaccurate, non-compliant results.

Applications — Where It Is Used

Soil hydrometers are standard equipment in geotechnical investigation, road and highway sub-base design (RHD projects), embankment and foundation studies (LGED, BUET labs), and agronomy research classifying soil texture for crop suitability. Reference standards like BNBC and ASTM D422 govern how these tests are documented in Bangladesh — a detail most competing listings skip entirely, which is exactly why this page needs to spell it out clearly.

Why Buy From ASTZ?

Every hydrometer sold through ASTZ ships as a genuine, calibrated unit backed by warranty support and nationwide delivery. Our team also provides technical guidance on choosing the correct model for your specific standard requirement — something a bare product listing can’t offer.

Frequently Asked Questions

What is the Bouyoucos scale used for?

It’s a specialized hydrometer scale reading percentage of soil in suspension directly, commonly used in agronomy-focused sedimentation tests.

How do I check hydrometer calibration?

Test it in distilled water at the reference temperature — it should read zero (or the manufacturer’s stated reference point) at that exact condition.

Which model should I buy for a certified lab report?

Choose the ASTM Grade Hydrometer (৳1,400) if your report needs to meet ASTM or BUET-recognized standards.
