LC4 Laboratory Temperature Controller

Temperature Controller

JULABO Temperature Controllers fulfill temperature-dependent measurement, control, safety and monitoring tasks. Modern control technology, space-saving design and high operating comfort are particular advantages. The units offer MULTI-DISPLAY (LED) and a splash-proof keypad. High and low temperature warning functions with an interval tone (patented) ensure safe operation. The built-in RS232 interface enables online communication with a PC. Typical applications: heating mantles, heating baths and heating mats.

Your advantages

  • PID temperature control
  • Bright, large LED display
  • Constant indication of setpoint and actual values
  • Splash-proof keypad
  • Adjustable high temperature cut-off
  • RS232 interface
