Product Overview
The YAW-300C is a high-precision mechanical testing instrument developed and manufactured by Zhejiang Yiyu Instrument Equipment Co., Ltd. It is specifically designed for testing the compressive and flexural strength of cement and related materials. This device features a combined design incorporating a dual-column compression structure and an electric-cylinder flexural structure, offering characteristics such as high precision, superior performance, high reliability, and ease of operation. It supports various advanced control modes, including constant test force rate, constant stress rate, and test force holding.
Core Design and Advantages
- Dual-Structure Design: The compression section utilizes a robust dual-column frame, while the flexural section employs a precise electric-cylinder drive, ensuring stability and accuracy across both testing modes.
- Exceptional Measurement Accuracy: The device achieves an accuracy class of 0.5, with the relative error of the indicated test force controlled within ±0.5%.
- High Resolution Throughout Range: The force resolution reaches an impressive 1/300,000 of the maximum test force, maintaining this high resolution consistently throughout the entire testing process.
- Intelligent Control System: Controlled via a microcomputer, the system can execute complex testing protocols, significantly enhancing laboratory automation levels and data processing efficiency.
- Safety Protection Design: As visible in the accompanying images, the testing area is equipped with a black honeycomb-patterned safety shield to ensure operator safety in the event of specimen fracture.
- Industrial-Grade User Interface: Features a central touch-screen display that provides real-time visualization of test curves and data, offering an intuitive and user-friendly operating interface.

Frequently Asked Questions (FAQ)
Q1: What are the power supply requirements for the YAW-300C?
A: Unlike certain small-scale consumer-grade electrical devices, the YAW-300C requires a 3-phase AC 380V ±10% power supply for operation, with a total power consumption of 1.1 kW.
Q2: Can this machine perform both compressive and flexural strength tests simultaneously?
A: Yes. It features an independent structural design (utilizing a dedicated electric cylinder for flexural testing and a single-acting hydraulic cylinder for compressive testing), engineered to facilitate efficient, integrated testing—whether performed simultaneously or sequentially.
Q3: What are the standard specimen dimensions supported by this machine?
A: The flexural testing section supports standard specimens measuring 40 × 40 × 160 mm; the compressive testing section features an effective test width and height of 180 mm each, allowing it to accommodate a wide variety of cement or mortar specimen specifications.
Q4: Does the force resolution vary across different load ranges?
A: No. A key feature of this equipment is its constant resolution across the entire measurement range; it consistently maintains a resolution of 1/300,000 of the maximum test force, thereby ensuring exceptional testing consistency.
Q5: What are the primary application areas for this equipment?
A: It is primarily utilized in the laboratories of construction material quality inspection stations, scientific research institutes, universities and colleges, as well as cement and concrete manufacturing enterprises, for conducting research into material mechanical properties and performing compliance testing.
