Overview
The Gradient-Oven 432 Smart is a laboratory instrument designed for the efficient measurement of temperature-dependent properties, particularly in the context of automotive finishes and industrial stoving processes. It simulates industrial stoving processes with programmable gradients and is available in two versions with operating temperatures ranging from 30 to 250 °C and 30 to 320 °C.

Purpose and Application
This equipment is crucial for assessing the resistance of coatings to environmental factors such as acid rain, bird droppings, and chemicals. It helps in determining the temperature range and maximum temperature limits where lacquer formulations begin to change, which is vital for quality testing and development of stove enamel systems.

Technical Description
The Gradient-Oven 432 Smart allows for the simulation of production processes by programming heat-up speed, baking temperature, and time. It features a microprocessor-controlled heating bench with 45 isolated heating elements, providing a linear or step temperature gradient. The oven is equipped with USB ports and a LAN connection for data output.

Testing Procedure
The oven can test coatings at temperatures up to 320 °C. It allows simultaneous application of two different coating systems on the same panel, facilitating comparison. Standard tests involve applying various chemicals on a panel and evaluating the thermal stress effects visually after specified intervals.

Execution and Safety
The device is a tabletop instrument suitable for non-hazardous environments. It includes safety features such as a holding device for test panels and a protective flap. The operation is menu-guided via a touch panel available in multiple languages.

Order Information
The Gradient-Oven is available in two models, each with specific operating temperature ranges. The package includes essential accessories like an exhaust tube, glass plate, test panels, and marking strips.

Technical Data
The oven operates at 230 V with a power consumption of 3400 VA. It features a heating surface of 520 x 100 mm and a test surface of 500 x 70 mm. The linear gradient allows a maximum temperature difference of 100 °C, while the step gradient offers up to 50 °C difference between steps. The device dimensions are approximately 470 x 860 x 585 mm, and it weighs around 103 kg.
