The BL931700 model offers a manual two-point calibration with pH values displayed out to two decimal places.
External Disabling Feature
A normally open contact may connect to a level controller or flow monitor. This safety feature may be used to prevent continuous dosing in the event of specific or undesired system conditions.
Adjustable Dosing Relay
The BL931700 features a dosing relay which may be configured to dose above or below a user programmable pH setpoint.
Selectable Overdose Protection
The mini controller may be programmed to deactivate a valve, pump, or connected device if its activation continues over a selected time; adjustable from 5 to 30 minutes.
Selectable Control Override
With the flick of a switch, normal “Auto” operation may be overridden turning your connected device “Off” from operation or always “On.”
