KL-601 Digital pH/Temperature Controller

The pH-601 Acidity/Temperature Controller is an integrated product featuring temperature display, temperature alarm, pH display, pH alarm, and control functions. 
It can simultaneously alarm for acidity (upper or lower limit) and temperature upper/lower limits. The alarm status can be directly observed through the color of the LED indicator—green indicates normal operation, while red indicates an alarm (for example, when the pH indicator LED on the panel lights up red, it signifies a pH out-of-range alarm). 
It adopts a wall-mounted design for easy installation, operation, and maintenance.
