Communication Functions
An optional mobile app control module enables real-time remote monitoring and operation of the oven. Users can track core parameters (e.g., temperature, operating status) in real time, send control commands, and view historical data curves via the app, greatly enhancing operational convenience and management efficiency.
Test Holes
Standard configuration includes one φ50mm test hole on each side, fitted with silicone plugs for airtight sealing. The quantity, size and layout of test holes are fully customizable and scalable to meet customers’ actual testing needs. Please specify your requirements in the order to ensure seamless integration with your testing processes and associated equipment.
Customization Services
We offer flexible and comprehensive customization services to meet the diverse demands of different industrial applications. Beyond standard specifications, key technical parameters (e.g., chamber dimensions, temperature range, heating rate, shelf load capacity and control system functions) can all be adjusted according to customer requirements. Our professional R&D and engineering team provides one-stop customization solutions covering the entire process from scheme design, prototyping to production and commissioning, ensuring the equipment fully aligns with your workflows and testing standards.
