CW-225B Digital Rebound Hammer — Professional Concrete Strength Testing for Bangladesh
The CW-225B digital rebound hammer solves a problem every site engineer in Bangladesh knows well. You need a concrete strength reading. The analog hammer gives you a rebound number. Now you pull out the chart, calculate, record — and wonder if the scale reading was accurate. The CW-225B removes every step of that uncertainty.
Press the plunger against the concrete surface. The instrument reads the rebound value, calculates compressive strength automatically, and displays the result directly in MPa on the LCD screen. No chart. No calculation. No second-guessing.
This is why the CW-225B has become one of the most popular digital rebound hammer choices among civil engineers, construction companies, and testing laboratories across Bangladesh — it delivers professional accuracy at a rebound hammer price in Bangladesh that makes practical sense for any budget.
CW-225B Digital Rebound Hammer — Why It’s the Best Choice in Bangladesh?
When comparing rebound hammer price in Bangladesh, most buyers face a choice between cheap analog models and expensive imported digital units. The CW-225B digital rebound hammer sits precisely in the right middle — genuine digital performance at a low price rebound hammer BD buyers can actually justify.
The key difference from a standard analog hammer is accuracy and efficiency. Analog models introduce reading errors at the scale. The CW-225B eliminates that entirely — the electromagnetic-assisted mechanism reads consistently, and the digital processor calculates the result before it reaches your hand.
For engineers submitting formal test reports to clients, government departments, or international consultants, this accuracy matters. Results from the CW-225B are clear, documented, and defensible.

Why these specifications matter for Bangladesh engineers:
The 10–60 MPa measurement range covers every standard concrete grade used in Bangladesh’s construction industry — from C15 residential slabs to C50 high-strength structural elements. You will not find a job site situation where this range falls short.
The ±3 MPa accuracy closely matches laboratory core sample results when used correctly. For most structural verification work, this is well within acceptable tolerance — and considerably better than a misread analog scale on a busy site.
The 2.207 Nm impact energy meets ASTM C805 and EN 12504-2 international standards — which means test results from the CW-225B are accepted by PWD, LGED, RAJUK, and international engineering consultants operating in Bangladesh.
At approximately 1kg, the CW-225B carries easily to any floor level, scaffolding platform, or remote concrete element — something that matters on multi-story construction sites where you might need 50+ readings in a single session.
HT-225 Analog vs CW-225B Digital Rebound Hammer — Which One Do You Need?
| Feature | HT-225 Analog | CW-225B Digital |
|---|---|---|
| Display | Physical scale — manual reading | Digital LCD — direct MPa display |
| Strength Calculation | Manual chart conversion | Automatic on-screen calculation |
| Reading Accuracy | Depends on operator skill | Consistent digital reading |
| Data Recording | Manual notebook | Direct readable result |
| Calibration Anvil | Included | Included |
| ASTM Compliance | Yes | Yes |
| Testing Speed | Slower — manual steps | Faster — instant result |
| Best For | Occasional testing, tight budget | Regular testing, formal reports |
| Price Range | ৳14,500 | ৳60,000 |
Choose HT-225 if: You handle occasional site checks, have a tight budget, and are comfortable reading an analog scale and doing manual chart conversion.
Choose CW-225B if: You test concrete regularly, need to submit formal reports, want faster on-site results, and need a professional-grade digital rebound hammer without paying premium brand prices. For most active engineers in Bangladesh, the CW-225B is the practical choice.

CW-225B Digital Rebound Hammer — Frequently Asked Questions
What is the CW-225B digital rebound hammer price in Bangladesh?
The CW-225B digital rebound hammer price in Bangladesh falls in the ৳60,000 range depending on current stock. Contact us directly for the latest price and any available offers. This represents genuine low price rebound hammer BD value for a fully digital instrument with calibration certificate.
What is the difference between the CW-225B and an analog rebound hammer?
The CW-225B displays compressive strength directly in MPa on the LCD screen — no chart conversion, no manual calculation. An analog model gives you a rebound number on a physical scale, which you then convert using a reference chart. The digital version is faster, eliminates reading errors, and produces cleaner results for formal documentation.
Does the CW-225B come with a calibration certificate?
Yes. Every CW-225B we supply includes a factory calibration certificate and calibration anvil. The certificate confirms the instrument was calibrated to ASTM C805 and EN 12504-2 standards — accepted by government departments and international consultants for formal engineering test submissions.
Can the CW-225B test concrete in existing buildings?
Yes. The CW-225B tests hardened concrete on both new construction and existing structures — columns, beams, slabs, retaining walls, bridge decks, and any accessible concrete surface. It is a non-destructive test, meaning no drilling or core sampling is required.
Do you deliver rebound hammers outside Dhaka?
Yes. We deliver to every district in Bangladesh. Dhaka delivery takes 1–2 business days. All other districts receive delivery within 2–5 business days via reliable courier partners with protective packaging for fragile instruments.
