Description
Product Introduction
The instrument is used in colleges and universities, research institutions, and testing laboratories, as well as in the metallurgical, construction, bridge‑building, hydropower, and other industries, for measuring the dynamic elastic modulus of concrete, carbon materials, slate, glass, bricks, plastics, and metallic materials.
Implementation Standard:
GB/T 50082 “Standard for Test Methods of Long-Term Performance and Durability of Ordinary Concrete”
JTGE 30 “Test Procedures for Cement and Cement Concrete in Highway Engineering”
Features:
1. Manual measurement of frequency sensitivity has reached 1 Hz, enabling frequency‑hopping sweeps from 100 Hz to 20 kHz—first with coarse sweeping in tens, hundreds, thousands, or ten‑thousands of hertz, followed by fine sweeping at higher resolution until accuracy is refined to 1 Hz.
2. Built-in memory: Can store data from 100 test runs, with features such as data export and centralized printing.
3. All‑Chinese LCD display: Shows the current scan frequency, the resonant peak frequency, and the signal strength in real time. Compared with oscilloscope tube displays from other manufacturers, it offers advantages such as intuitive operation, high accuracy, and easy reading.

YLZ-100 Microcomputer-Controlled Electro-Hydraulic Servo Curbstone Flexural Testing Machine
The YLZ-100 concrete curbstone flexural‑compressive testing machine is used to determine the flexural strength and flexural load of linear curbstones with a length of 1000 mm, as well as the compressive strength of curved curbstones and L‑shaped curbstones with a straight cross‑section. In accordance with JC/T 899‑2016 Concrete Curbstones, it can also be employed to conduct experimental studies on the flexural and compressive strengths of other materials.
The microcomputer-controlled high‑ and low‑temperature electronic universal testing machine consists of the testing machine mainframe, fixtures, a high‑ and low‑temperature chamber, and computer software. The temperature chamber is slid into the mainframe; after opening the chamber door, the specimen is secured in the dedicated fixture. The chamber then heats or cools until the specified temperature is reached.
