Questions & Answers

Q: What is the measurement range and value of steel anvil?

A: Measurement range is: C10--60Mpa，value of steel anvil: 80±2

Q: Is the value shown on the scale the intensity value?

A: No, this is the rebound value.you can first measure the hardness value of the concrete surface with the rebound meter. Then you can refer to the instructions to calculate the intensity value by putting the hardness valuethe in a certain formula.

Q: How many times does the hammer need to be fired to measure the concrete so that it can test the concrete strength more accurate?

A: The national standard requires that one component needs to measure ten measurement areas, and each measurement area measures 16 measurement points. During the measurement process, that is, too large or too small values are to be excluded and the 16 valid values are retained, after the three largest and minimum ones are removed. then get the average.Then Refer to the instruction manual to obtain the strength value of the measurement zone and calculate the standard deviation with a certain formula and finally getthe strength value of the component.

Q: I don't want to be so cumbersome. Do you have a way to simply look at the approximate strength of concrete?

A: First,you must calculate the average rebound value calculated by the bombing 16 times and then compare it with the comparison table below the ruler. The red line represents the live concrete ,the green line represents the commodity concrete, and the approximate strength value of the concrete is checked according to the coordinate line.


*Operation instruction First,measure the average rebound value of concrete ( Rm ) using the Concrete Rebound Hammer Then refer to the instruction manual to obtain the strength value of the measurement zone and calculate the standard deviation with a certain formula finally get the strength value of the component.	*Maintenance cycle Maintenance is required when one of following occurs: 1.Value of Steel anvil rate is extremely erroneous. 2.Worked for over 2000 times. 3.Stored for more than 6 months 4.The anvil rate is too low The Maintaining Method is detailed instructed in the manual.	*Calibration Certification All Hammer from us is in accordance with technical regulation of JGJ/T23-2001 with Verification Certification Shanxi Institute of Building Research, who composed "Testing Concrete Compressive Strength Technical Regulation of JGJ / T23-2001 with Springback Method", supervises the manufacturing process.
