Introduction Proceq OS8200 Schmidt Rebound Hammer
The Proceq OS8200 Schmidt Rebound Hammer is the most advanced digital concrete strength testing instrument available today. Engineers and quality inspectors across Bangladesh and worldwide rely on this Swiss-made non-destructive testing (NDT) device to evaluate concrete compressive strength and uniformity with unmatched accuracy and speed. Traditional rebound hammers produce an R-value that gravity, internal friction, and impact anglez.

Frequently Asked Questions (FAQ) Proceq OS8200 Schmidt Rebound Hammer
Q1: What is the difference between the Proceq OS8200 and a classical Schmidt Hammer?
The Proceq OS8200 uses optical technology to measure the Q-value (ratio of rebound to impact velocity), while classical hammers measure the mechanical R-value (hammer travel distance). The Q-value is free from gravity effects, internal friction errors, and impact angle variation — problems that affect every classical rebound hammer currently on the market. The OS8200 delivers lower dispersion, higher accuracy at high strength, and requires no angle correction at any orientation. Proceq OS8200 Schmidt Rebound Hammer
Q2: Which standards does the Proceq OS8200 comply with?
The OS8200 complies with EN 12504-2, ENV 206, ASTM C805, ASTM D5873 (rock), BS 1881 Part 202, and JGJ/T23 (Chinese standard). The Proceq Live app automates EN13791 screening test report generation and supports multiple regional standards.
Q3: What concrete strength range does the OS8200 cover?
The Type N hammer tests 10 – 100 MPa for normal and high-strength concrete, and up to 120 MPa for Ultra-High Performance Concrete (UHPC). The Type L hammer tests 5 – 30 MPa. With the optional mushroom plunger accessory (Type L only), you can test fresh concrete as soft as 5 MPa — ideal for early-strength and formwork removal decisions. Proceq OS8200 Schmidt Rebound Hammer
Q4: Does the Proceq OS8200 require impact angle correction?
No. The OS8200’s optical Q-value measurement system requires no angle correction regardless of impact orientation — vertical, horizontal, upward, or downward. This is a major advantage over classical R-value hammers, which require manual correction tables for non-horizontal impacts.
Q5: How does the Proceq Live app work with the OS8200?
The OS8200 connects to the Proceq Live app on iOS or Android via Bluetooth Low Energy. The app receives impact data in real time, calculates series statistics, and stores measurements with geolocation, voice notes, photos, and text annotations. It generates single-series and multi-series reports in PDF and CSV format instantly and uploads data to the cloud for remote access and team collaboration.
Q6: How long does it take to complete a concrete test region assessment?
The OS8200 completes a full test region assessment in under 10 minutes, compared to days of effort required by core drilling and lab compression testing. The digital workflow, auto-calculation, and instant reporting eliminate manual data recording entirely.
Q7: What is the battery life of the Proceq OS8200?
The OS8200 uses one standard AAA battery (alkaline or rechargeable) with a battery life exceeding 20,000 impacts per charge. A Micro-USB charging cable is included with every instrument.
Q8: Can I create custom material curves for my specific concrete mix?
Yes. The OS8200 and Proceq Live app support full custom material curve creation. You record Q-values at locations where you extract concrete cores, crush the cores in a press, and enter the compressive strength data into the app’s simple spreadsheet function. The app then builds a site-specific calibration curve that delivers the highest possible accuracy for your concrete mix design.
