Digital PID control with a calibration offset holds temperature accurately throughout that range, supporting drying, curing, and sterilization tasks.\u003c\/p\u003e\n\u003ch3\u003eWhat is the chamber capacity and overall footprint?\u003c\/h3\u003e\u003cp\u003eThe chamber holds 74 L. Overall dimensions are 36 × 36 × 39 in (L × W × H), and the unit weighs 170 lbs, so plan adequate bench or floor space and clearance before installation.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between the DX402C and DX412C?\u003c\/h3\u003e\u003cp\u003eVoltage is the only difference. The DX402C runs on 115V and the DX412C runs on 220V; both share the same 74 L chamber, ambient +5 to 300°C range, and digital PID control. Select the model that matches your site power.\u003c\/p\u003e\n\u003ch3\u003eWhat materials are used in the oven construction?\u003c\/h3\u003e\u003cp\u003eThe interior is stainless steel for corrosion resistance and easy cleaning. Its exterior is steel plate (SPCC) with a powder-coat finish that protects the unit on the bench.\u003c\/p\u003e\n\u003ch3\u003eDoes this oven use natural convection or forced air?\u003c\/h3\u003e\u003cp\u003eThis is a natural (gravity) convection oven. Air circulates without a fan, which reduces sample disturbance and particle movement inside the chamber during drying.\u003c\/p\u003e\n\u003ch3\u003eIs the DX402C manufactured under recognized quality standards?\u003c\/h3\u003e\u003cp\u003eYes. It is produced under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certified management systems.
