Specification

Product name: Concrete rebound tester

Model: HT-225

Color:

HT-225 (Metal Housing)

HT-225B (plastic shell)

The HT-225 concrete rebound tester is a newly developed and produced mechanical rebound tester. The product complies with the GB/T9138 standard for rebound testers.

Features:

1. The stylish and lightweight shell greatly reduces your work intensity

The outer shell of the instrument is made of polymer composite materials with excellent impact strength. This material is widely used in aviation, construction, machinery and other fields due to its excellent impact strength, creep resistance, heat resistance, cold resistance, electrical insulation, etc—— Jinwei uses it as the shell of the rebound tester, achieving a low-carbon and efficient concrete detection tool.

2. The rebound device has an ultra long service life

The important components of the HT-225 rebound instrument have undergone systematic technical improvements, and the strict quality control process has improved the overall performance of the rebound instrument, extending its maintenance cycle and service life.

3. Shell color coating - elastic rubber paint

The shell sprayed with elastic rubber paint has a viscoelasticity that damps and reduces structural vibration and noise, and has a special soft touch and high elastic surface feel; Impact resistance, recoverability, soft touch, even and smooth paint film, and strong chemical resistance.

explain

Complies with GB/T9138-1988 standard, JJG817-93 regulations, and JGJ/T23-2011 technical regulations.

The HT-225B concrete rebound tester is suitable for testing the strength of general building components, bridges, and various structural components (slabs, beams, columns, and bridge trays).

characteristic

1) The central guide rod is made of imported materials, with high accuracy and wear resistance;

2) The shell is made of polymer composite material, which has good elasticity and avoids damage to the instrument during on-site operations, extending its service life;

3) The pointer slider adopts an external spring coil structure, which is convenient for adjusting friction and ensures even friction between the pointer shaft and the pointer slider, ensuring the accuracy of the instrument. Compared to peer products, it has high precision and long service life.
