HS-55 Recirculating Coolers (Advanced Low Temp. Models)

Product Description

Adjustable, precise PID temperature controller beneficial for various cooling tasks, for use in the science, research, and industrial laboratories. Innovative and exclusive controller can be adjusted the cooling capacity from 1% to 100%.

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.
If the equipment operates at 40 or above due to the external environment, user can simply identify the
error with a visual or an audible sound.
Designed to simplify operation with a touch screen type display.
– Easy-to-read VFD display with interactive touch keys
– Setting and resolution indication 0.1 /
– Quick keypad lock prevents accidental parameter changes
– Signal indicator for operation status
