DF412 / DF612 / DH412 / DH612

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.

DF & DH Series is a Highly reliable and accurate fine oven with simple settings for various temperature characteristic tests requiring complicated programming.

Improved visibility and operability of control panel.
Precise temperature stability & uniformity.
Standard equipped with adjustable air speed function and displays of power consumption, CO₂ emission and heat timer.
Enhanced program operation function (maximum 99 steps, 99 patterns, repetitive operation function).
Improved safety with fan motor error detection.
Exhaust damper allows quick exhaust and cooling of inside chamber.
Equipped with exhaust and cable ports.

Safety features:

Self-diagnosis circuit (abnormal temp. sensing, heater disconnection, auto overheat prevention, SSR short circuit), overheat protector, earth leakage breaker, key lock and door switch.
