Introductions

Conform to GB/T9138-1988 standards and JJG817-93 procedures and code of JGJ/T23-2011. This product is suitable for surveillance companies, quality supervision and on-site sampling and testing centers. Results automatically, without manual calculations.

Features

1) bouncing device is in accordance with the technical specification for inspection of concrete compressive strength (JGJ/T23-2011) independent research and development, have complete independent intellectual property rights.

2) integrated structural design of domestic initiative, will rebound hammer host sensor fusion of organic and rebound as a whole, without any cable, portable and low failure rate.

3) spearheaded the introduction of true color LCD screen, resolution 176x220, Chinese interface, convenient operation.

4) unique rebound value voice prompt function, can be known without viewing screen rebound value and improve staff efficiency.

5) rebound sensor non-contact metal grating sensor, completely avoids the use of potentiometers or other-contact sampling methods are prone to mechanical wear and tear, defects such as bad, with high precision, long life and other characteristics, while retaining a mechanical pointer ruler.

6) can be an external infrared portable printers, test reports can be generated on site.

7) large capacity data memory, stores up to 200 standard components, a standard component can detect a maximum 99 the survey area, fully meet the needs of actual work.

8) instruments built in the unified national curve, and may increase the area or curve replaced at any time by the user, stores up to 20 measuring curve.

9) component and measured parameters of field recording, and automatic calculation of component results.

10) automatically removed the outliers features can be set by the user on the rebound, lower limit, and the use of screens and voice prompts.

11) using the USB communication port and virtual USB drive, no need to install any driver, you can export data or replacement of special strength curve.

12) with a real-time clock and calendar functions, you can automatically record test dates and times for each component.

13) advanced low-power power-management features, you can set the backlight of the screen, voice volume, auto sleep and auto power off function, improve the use of time.
