1. Intended use
Fulfilling its principle task, reliable temperature control and measurement, the LC4 temperature
controller also implements safety and monitoring functions, particularly in the areas of chemical
research and quality control. The sophisticated capabilities of the unit allow wide application
with electrical heating devices such as
heating hoods, heating baths,
heating pads and bandages,
water and oil baths.
JULABO Temperature controllers are not suitable for direct temperature
control of foods, semi-luxury foods and tobacco, or pharmaceutical and
medical products. Direct temperature control means unprotected contact of the
object with the bath medium (bath fluid).
1.1. Description
Setting is rapid and simple using the keypad with its easy to learn symbols. Keypad is splash-
proof, easily cleaned and ergonomically designed. The microprocessor technology allows the
working temperature setpoint and five parameter sets to be stored and indicated on the
MULTI-DISPLAY (LED).
The safety value for excess temperature protection, a safety installation independent from the
control circuit, is adjustable on the front and visible on the MULTI-DISPLAY (LED).
The RS232C port permits modern process engineering without additional interface, directly on-
line from the controller to your application equipment.
