This test chamber is designed and manufactured in accordance with national standards for the standard curing of gypsum board specimens.

Gypsum board shear-force bracket / Gypsum board hardness steel pin

The shear‑force testing frame for gypsum board is used to determine the shear strength of gypsum board.

DKZ-II Type Gypsum Board Flexural Testing Machine

It is suitable for flexural strength testing of gypsum board. The testing machine features an elegant appearance and meticulous craftsmanship, and is equipped with a servo control system that ensures uniform loading, high efficiency, and excellent stability.

MX-II Type Gypsum Board Surface Water Absorption Tester

Paper surface absorption weight tester, suitable for determining the water absorbency of various papers and paperboards.

BS-II Type Gypsum Water Retention Tester (Pointer Type)

To determine the water retention of plaster.

BS-III Type Gypsum Water Retention Tester

The gypsum water-retention tester features automatic pressurization, automatic constant-pressure control, and automatic test termination, eliminating the need for manual supervision. It can also be used for water-retention tests on cement and mortar.

CHD-50 Type Gypsum Consistometer

This instrument is a specialized device for determining the standard consistency of building gypsum; accordingly, it is suitable for production facilities that manufacture building gypsum products as well as for relevant research institutions.

DM-II Gypsum Abrasiveness Tester

This instrument is primarily designed to assess the grindability of joint‑filling gypsum used on interior walls, ceilings, and other surfaces. It features a well‑designed, reliable structure, simple operation, automatic counting, and excellent overall repeatability.

BX-100 High-Strength Gypsum Deformation Tester

It is suitable for determining the amount of deformation of mortar during the hardening process.

SYD-10 Type Gypsum Hardness Tester

The gypsum hardness tester is used to determine the hardness of gypsum. A steel ball is placed on the test specimen, and the depth of the indentation under a specified load is measured; the gypsum hardness of the specimen is then calculated from this measurement.

RZ-100 Type Gypsum Bulk Density Tester

A specialized instrument primarily used for determining the bulk density of building gypsum.

SGSX-III Type Gypsum Phase Composition Analyzer

The gypsum phase composition analyzer is a rapid-testing instrument specifically developed for the gypsum industry, designed to determine the three-phase content of gypsum, its purity, and the levels of adsorbed water and crystal water. It meets the moisture‑content and three‑phase analysis requirements at every stage of research and production processing. The device is widely used for fast determination of gypsum’s three phases and moisture content in raw materials, powders, granules, semi‑finished products, finished goods, and other materials.
