By simulating controlled ozone-rich environments, this device ensures early detection of cracking, surface degradation, and material embrittlement. With precise ozone concentration control, temperature regulation, and real-time monitoring, the device allows manufacturers to validate rubber durability before deployment in automotive, aerospace, industrial, and consumer applications.

As a leading manufacturer of environmental testing equipment, LIB industry offers multiple standard models of ozone testing devices with customizable options, including chamber dimensions, ozone concentration levels, temperature ranges, and control systems. It delivers reliable, repeatable, and safe ozone aging tests for all types of rubber, including natural, synthetic, and blended compounds.

Why Test Rubber for Ozone Deterioration?

Testing rubber under controlled ozone exposure is critical for product longevity and safety. Ozone can cause:

Surface cracking and micro-fissures – Rubber compounds can develop ozone cracks even at low stress levels, compromising sealing and insulation.

Material embrittlement – Prolonged ozone exposure accelerates aging, reducing elasticity and tensile strength.

Loss of mechanical integrity – Critical components like O-rings, gaskets, and seals may fail, risking leaks or equipment malfunction.

Premature product failure in extreme environments – Automotive tires, hoses, and industrial belts are highly vulnerable to ozone-induced deterioration.

By using an ozone testing device, manufacturers can identify weak rubber formulations, optimize compound additives, and improve product reliability in ozone-prone environments.

Key Advantages of the Ozone Testing Device for Rubber Deterioration

Precise Ozone Generation and Control
Adjustable ozone concentration from 0.1 to 200 pphm with ±2% accuracy. Ensures uniform exposure across all rubber samples for reliable aging tests.

Stable Temperature and Humidity Control
Chamber temperature range 0°C to +100°C with ±0.5°C fluctuation. Relative humidity adjustable from 30%–98% RH, maintaining consistent test conditions per ISO 1431-1.

High-Uniformity Airflow System
Optimized internal air circulation guarantees even ozone distribution and avoids local hotspots, critical for multi-sample or large rubber strips testing.

Programmable Multi-Step Test Profiles
Advanced touchscreen controller allows up to 99-step test programs, real-time data logging, and automatic reporting for compliance and traceability.

Static & Dynamic Test Configurations
Supports static (unstressed) specimen exposure and dynamic tensile strain testing up to 35% elongation. This reflects real-world deformation for automotive seals, tire sidewalls, and high-flex elasticity components.

Safe Exhaust & Door Lock
Activated-carbon filter treats ozone before release, while an electromagnetic lock prevents opening until safe, ensuring operator protection.
