Product Introduction

1. Purpose and Characteristics

The NJ-800 in-situ compression machine (in-situ axial compression tester) is developed and produced based on the in-situ axial compression method in Section 4 of GB/T50315-2011. It is suitable for estimating the compressive strength of 240mm thick ordinary brick masonry or porous brick masonry. This equipment has the characteristics of simple operation, accurate measurement data, and convenient portability. It is currently a commonly used testing instrument and the preferred equipment for comprehensive evaluation of compressive strength of brick masonry on site.

2. Features: Large tonnage, integrated design of digital display meter and hydraulic pump, precise indication, peak maintenance, and data storage.
