Blue M ESP 400 Series Mechanical Convection Oven

Product details

The Blue M ESP-400 Mechanical Convection Horizontal Air Flow Oven provides you with reliable performance. The ESP-400 convection oven is ideal for constant temperature work and for applications where fast run-up and cool-down rates are required. A one-pass air flow system allows incoming air to pass over the heaters and through the work chamber only once, if desired, enabling fast cool down or quickly venting non-hazardous fumes or moisture. 

Horizontal air flow offers excellent temperature uniformity. The setpoint and process variables appear on a bright, easy-to-read LED display and are adjustable to 1°C resolution. The main control regulates temperature by switching heater power through a solid state relay circuit.  An FM-approved over-temperature protection system is also provided.
