The rubber is subjected to controlled deteriorating influences for definite periods, after which appropriate properties are measured and compared with the corresponding properties of the unaged rubber.
This air oven method of ageing exposes a test sample to elevated air temperatures, allowing its physical properties, such as tensile strength, to be measured and compared with those of an unaged sample.
Avoiding the need for valuable bench space, the O7E is designed as a complete unit with its own stand and castor wheels.
The oven is a solid aluminium block with seven vertical cells machined from it. Preheated air at a controlled temperature is pumped from a manifold through a calibrated opening into the bottom of each cell, ensuring even air and temperature distribution.
To avoid contamination from re-circulation, the air is discharged to the atmosphere through the two covers at the top of each cell. The test samples are suspended from the inside of the top cover.
The oven includes a PID temperature controller with digital display. The controller is auto-tuning, achieving a high level of accuracy and stability at the working temperature. Alarms on the controller abort the tests if the temperature goes outside its operating band.
A valve positioned on the top of the control module regulates the airflow, which is measured accurately by a calibrated
flow-meter.
A USB communication option is offered, allowing connection to a PC.
-
The O7E is commonly used for rubber, elastomers, seals, gaskets, cables, and polymer-based materials.
-
Yes. The oven has adjustable airflow, and airflow is measured using a calibrated flow meter.
-
Yes. Because each sample is isolated in its own cell, different compounds can be tested at the same time without contamination concerns.
-
Unlike conventional ovens where samples share the same chamber, the O7E isolates samples into separate cells to improve testing reliability and reduce contamination risks.
-
Yes. The system includes over-temperature protection and alarm functions designed to protect both samples and operators during testing. The safety temperature cut-out, has thermostats that switch off power if the cell temperature exceeds 280°C, and it will not auto-reset after a power failure.
-
Yes. The O7E supports MODBUS communication via its USB port, allowing test data to be transferred to and monitored from a PC.
