Inquire product

DN411IE / DN611IE

Laboratory Oven is essential for general heating routines from drying food samples to curing microchips.  Lab Oven is one of the fundamental instruments every laboratory should have.

DN Series is an Inert Gas Oven suitable for temperature test and heat treatment in a non-oxidizing environment, by introducing N₂ gas into the chamber.

Heat resistance test and heat treatment of up to 360°C.
Simple operation by interactive key input.
Standard equipped with various operation modes such as program operation and calibration offset function, power failure recovery mode selection, and user configuration information saving.
Repeatable operation function up to maximum 99 steps, 99 patterns controller with repeat function.
N₂ gas flow amount controllable.

Safety features:

Enhanced safety countermeasure, including self-diagnostic functions,  digital  setting,  independent  overheat  prevention device and electric leakage breaker.

In case of door opening during operation, fan and heater turn OFF by door switch.
