Operating features

� Temperature range is from -20 ~ 40 .
� As an option an external sensor can be directly installed into the cooling circuit for monitoring and
regulating of temperatures.
� Precise temperature stability ± 0.2 ( at 15 ) without heater.
� Bright LED water level indicator can be easily identified.
� Low fluid level and dry-running protection when triggered shows an error symbol on the display and an
audible sound.
