Keterangan
CONCRETE TEST HAMMER (CO-550 Series), ASTM C-805
Code Series : CO-550.4S
Model : Digital Concrete Test Hammer
Type : DIGI-Schmidt 2000
DIGI-Schmidt 2000, New rebound measuring sensors & microprocessor for rapid & reproducible results, plus resolution unattainable with older manual models. Hammer connected to control display via cable. Digital display of strength values, mean value, and standard deviation for preset number of measurements. User select menu for hammer impact direction and desired engineering units (psi, MPa, kg/cm2, or N/mm2). Indicates specimen size & type for which data predicted. Measuring range 10 to 70 N/mm2 compressive strength.
SILVERSCHMIDT
Proceq has combined the best of Original Schmidt with the most advanced technology to create the new SilverSchmidt concrete test hammer.
The SilverSchmidt offers a virtually maintenance free, lightweight and compact construction.
This next generation tool combines an electronic display and advanced mechanics with true rebound coefficient that automatically converts to compressive strength.
Features :
Measurement inherently independent of impact direction, meaning no directional corrections are necessary
- High measuring accuracy due to differential optical absolute velocity encoder
- Conversion curves for a wide range of compressive concrete strengths, including low fc (10 N/mm2, 1â450 psi) and high strength concrete (up to 170 N/mm2, 24â650 psi)
- Simple operation with "one-button", combined with advanced tilt and twist technology user interface
- Language independent graphical menu with symbols
- Automatic conversion to the required measurement unit (N/mm2, kg/cm2, psi)
CONCRETE TEST HAMMER Type NR
Concrete testing with the Original Schmidt test hammer is the most frequent used method for non-destructive concrete testing worldwide.
For every demand and specific test application, Proceq offers the right concrete test hammer.
Original Schmidt concrete test hammers are available in models with different impact energies in order to meet the needs to test a wide range of material types and sizes.
Types NR are best-suited and specially developed for assessing the quality and compressive strength characteristics of concrete with the range of 10 to 70 N/mm2 (1â450 to 10â152 psi).
Versions incorporating paper chart recorders (LR and NR) can automatically register the rebound values on a paper strip chart.
Type NR: Rebound values are recorded as a bar chart on a paper strip which has a capacity for 4â000 test impacts
Applications :
- Used for the non-destructive measurement of the concrete/mortar compressive strength characteristics
- Control of uniform concrete quality (in-situ concrete and prefabricated structures)
- Detection of weak spots in the concrete
Standardization:
ISO/DIS 8045, EN 12 504-2, ENV 206, DIN 1048 part 2, BS 1881 part 202, ASTM C 805, ASTM D 5873(Rock), NFP 18-417, B 15-225, JGJ/T 23-2001, JJG 817-1993
