Highly reliable oven to enable high accuracy

Fluorescent display tubes are employed as the sub indicator to support "katakana" indications. Highly reliable accuracy oven with simple settings for various temperature characteristics test that require complicated programming.

Employed main and sub displays and a jog dial with a center switch. The user can operate the unit simply and quickly with only one dial that enables interactive operation with "katakana" display, invoking setting information, and determination of settings.
Operating status and current operating conditions are clearly indicated as character information on the sub display.
The temperature display of the unit uses a 7-segment LED and fluorescent display tubes for setting and operation information to assure high visibility.
Fluorescent display informs the user the operation status of the heater and the fan.
There is dedicated keys for program input (up to 16 segments) and edit to enable quick access.
Exhaust damper allows quick exhaust and cooling of inside.
Accumulated timer function useful for maintenance and management is equipped as standard.
Cable port useful for a monitor for temperature during testing is equipped as standard.
