Frequently Asked Questions (FAQ)
Q1: What types of curbs is this machine mainly used to test?
A: It is mainly used to test the flexural strength of straight curbs with a length not exceeding 1000mm, and the compressive strength of irregularly shaped curbs (such as L-shaped or arc-shaped).
Q2: How do I switch between compressive and flexural functions?
A: The main unit is designed with removable compressive components, allowing users to easily install or remove relevant parts according to experimental needs, thus quickly switching functions.
Q3: Is the measurement accuracy of this equipment guaranteed?
A: Yes. Its accuracy class reaches 0.5, thanks to its built-in high-precision 0.5-class load sensor, which maintains good accuracy and repeatability even during long-term use.
Q4: Is the support span adjustable?
A: Yes. To accommodate different sizes of curb stones, the span adjustment range of the equipment is between 150mm and 1000mm, and the adjustment process is very convenient.
Q5: What are its power requirements?
A: This equipment supports 380V or 220V AC power (±10%), with a rated power of 1.5kW, and can adapt to most standard laboratory power environments.
