QM240S Air-Vent Thermal Aging Oven

The QM240S air-vent thermal aging oven is built to ISO 188 for hot-air aging of plastics and rubber, evaluating property changes under sustained heat exposure.

To prevent deformation and abnormal degradation from gases and organic compounds released during aging, the oven exhausts and refreshes air periodically, keeping the air speed reaching specimens uniform (0.5 m/s ± 0.25).

Range RT~400 °C; color LCD touchscreen plus digital PID control with saved data; fitted with a speed-adjustable detachable rotating rack (3~8 rpm).

Air-Vent Thermal Aging Oven
ISO 188 Standard Model

The QM240S air-vent aging oven is built to ISO 188 for hot-air aging of plastics and rubber and measuring property changes under sustained exposure. It exhausts periodically and keeps reaching air speed uniform (0.5 m/s ± 0.25) to avoid secondary contamination. Range RT~400 °C; color LCD with digital PID; detachable rack at 3~8 rpm.

From rubber seals to plastic parts - gases released during aging can skew results; the air-vent design exhausts them periodically to ensure accurate, repeatable aging. ISO 188 is the international standard for rubber hot-air aging.

Designed for standardized aging - air vent plus uniform air speed, ISO 188 rubber-aging compliant.
