DF832 / DF1032 / DH832 / DH1032

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 Large Capacity Series is a High Performance fine oven designed to support high throughput with high accuracy temperature control and exhaust damper.

Allows precision maintenance of large parts at a constant temperature.
Quick exhaust and cooling in the unit with the exhaust damper.
Interactive key entry on the control panel with a green LED digital display for easy settings.
Features power consumption /CO₂ emissions monitoring.
Increased safety and self diagnostic functions.

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.
