DNE Series – Energy Saving Programmable Oven

Inquire product

DNE411 / DNE611 / DNE811 / DNE911

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.

DNE Series is a High performance environment friendly eco-oven that reduces power consumption significantly.

High precision controller allows high performance temperature control and display of CO₂ and power discharge.
Heat tightness and insulation design of the chamber achieves an energysaving rate of about 40% at constant temperature compared to previous models.
Maximum temperature reaching time reduced by 15 minutes (no-load) compared to previous models.
Program operation with a maximum of 99 steps, 99 patterns repeatable.
Standard equipped with various support functions such as calibration offset, power failure recovery mode, save and access of user setting information, as well as other operation modes.
Data acquisition from internal test device possible because of cable holes.
Easy system upgrade with various option settings.

Safety features:

Standard equipped with various self-diagnostic functions such as independent overheat prevention device, overcurrent circuit breaker, and key lock function.
