Apparatus Construction

Cabinet: Double-walled structure with a stainless steel inner chamber and a mild steel outer body, duly painted for durability.
Inner Chamber Dimensions: Approx. 33 cm × 46 cm × 26 cm (W × H × D)
Observation Door: Fitted with a full-view glass window to observe specimens during testing.

Performance & Controls

Temperature Range: Ambient to 200 ± 3°C at the sensor point.
Controller: PID controller with dual digital display for set and process values.
Air Circulation: Designed for 8–20 air changes per hour, ensuring uniform temperature distribution.
Air Inlet/Outlet: Air enters from the bottom, flows over the test pieces, and exits near the top for efficient circulation.
Air Flow Meter: Monitors and controls airflow rate.
Optional Accessory: Air Compressor & Laser height gauge (available on request).

Testing Features

Grips: Provided at the top of the oven to hang up to two specimens conveniently.
Weights: A complete set of calibrated weights (up to 1 kg) supplied with each unit for load application.
Elongation Measurement: Equipped with external non-contact distance measurement laser height gauge to read elongation directly without opening the chamber door, maintaining test conditions.
Sample Capacity: Up to four samples can be hung, but two are recommended to avoid contact between weights.
Timer: Built-in timer (up to 99 minutes) as per the latest IS amendment.
