Product Overview
The KR-702B digital Izod impact tester is dedicated cantilever beam pendulum equipment for measuring impact toughness of rigid non-metallic materials. It simulates instantaneous shock loads that plastic products encounter during transportation, assembly and daily use, clamping notched test strips vertically and releasing calibrated pendulum to deliver fixed impact energy. The system automatically calculates absorbed impact energy and impact strength after specimen fracture, providing quantitative data for raw material incoming inspection, new formula development and finished product safety verification.
This device strictly complies with ISO 180, GB/T 1843 and JB/T 8762 industry standards, adopts high-precision angle encoding acquisition and touch intelligent control, built-in thermal printing module for on-site report output. It is widely deployed in modified plastic factories, nylon composite manufacturers, electrical insulation labs, university material departments and third-party quality inspection institutions.
Core Product Advantages
- Multi-Grade Interchangeable Pendulum Energy Configuration
Two complete equipment specifications available for selection: low-energy 5.5J version (1/2.75/5.5J pendulums) and high-energy 22J version (11/22J pendulums). All pendulum rods use low-friction rotating bearings to reduce energy loss during swinging; energy control error is controlled below 0.5% for high-energy groups and 1% for low-energy groups, ensuring consistent parallel test data repeatability.
- High-Precision Digital Encoder Data Collection
High-resolution angular sensing chip tracks pendulum swing angle in real time, automatically deducts friction loss without manual dial reading. The touch screen displays impact energy, specimen intensity, friction loss and test batch statistics synchronously, with minimum energy resolution reaching 0.01J to capture tiny toughness differences of similar modified materials.
- Standardized Alloy Impact Blade & Precise Fixture
All striking blades follow standard 75° angle and R0.8mm tip radius, the vertical distance from blade to fixture jaw is fixed at 22±0.2mm. The adjustable clamping base firmly locks standard 80mm plastic test strips without offset during impact, eliminating data deviation caused by irregular specimen positioning.
- Fully Enclosed Anti-Splash Safety Cabinet
Integrated double-sided transparent protective housing completely isolates broken fragments during fracture testing; the cabinet door interlock design automatically locks the pendulum release circuit when opened to prevent accidental injury. Ventilation mesh panels on both sides dissipate heat generated by long-hour continuous testing, extending control system service life.
- All-In-One Touch & Thermal Printing Control
7-inch color touch operation panel integrates zero calibration, batch counting and parameter storage functions. After each group of tests, users can trigger the built-in thermal printer to output complete test slips containing specimen size, impact energy and average toughness values, realizing paper-based traceable archives without computer connection.
- Stable Integrated Bench Structure
Thick cast steel base matched with four leveling foot pads eliminates vibration during heavy pendulum impact, preventing machine displacement that affects swing precision. Standard single-phase 220V power supply, compact overall size occupies limited laboratory counter space, easy to move between test stations.

Standard Complete Test Operation Workflow
- Equipment Calibration Pre-Check
Power on the touch control system, perform pendulum zero calibration without specimens; check cabinet door safety interlock and thermal printer paper supply, confirm the selected pendulum matches material test requirements.
- Specimen Clamping Fixing
V-notched standard plastic test strips are vertically inserted into the cantilever fixture, tighten the locking bolt to ensure the notch aligns exactly with the pendulum striking center line.
- Pendulum Lifting & Locking
Manually lift the pendulum to the 150° fixed angle position, confirm the electromagnetic chuck locks the swing arm stably without slipping.
- Automatic Impact & Data Capture
Tap the test start button to release the pendulum; after striking and specimen breaking, the sensor instantly collects swing residual angle and automatically calculates the energy absorbed by the sample.
- Data Storage & Report Printing
Save single specimen data to the built-in memory, after finishing a batch of parallel tests, trigger the print function to generate standardized inspection slips with all group average values.
- Post-Test Cleaning & Shutdown
Open the safety cabinet to collect broken specimen fragments, wipe dust on the fixture and pendulum blade, lower the pendulum to rest position and cut off main power supply.
