DH650

Fine Oven 500 deg.C, Forced Convection

DH650

Operating temp. range

Room temp. +10 deg.C to 500 deg.C

Temp. distribution accuracy

+/-5 deg.C (at 500 deg.C)

Internal capacity

216L

A high temperature fine oven for heating at up to 500 deg.C

A fine oven with the highest heating temperature 500 deg.C.
Allows quick cooling in the unit with the exhaust damper.
Four-fold overheat preventive functions (automatic overheat prevention, heater room overheat prevention, overheat prevention in the bath, and temperature fuse) assure the optimal safety. The product also facilitates the self diagnostic function, the alarm history monitoring function, the key lock function and an over-current electric leakage breaker.
Abundant functions (external communication that supports RS485/FORWARD, external alarm, time-up, output on the logger) allow upgrading of the system according to the specific application.
