The BL931700 is a compact single setpoint pH controller designed for applications where space and/or cost are important. It?s adjustable dosing relay may be configured to dose above or below a pH setpoint. Users may choose from automatic or manual dosing modes allowing for easy maintenance and troubleshooting. The device contains a high impedance pH input and may be used with any pH electrode that has a standard BNC connector.
Large Clear LCD
A large LCD clearly displays the parameter you are monitoring.
Fire Retardant Casing
Special materials provide additional protection in the event of an emergency.
BNC Connection
The controller?s high impedance pH input may be used with any pH electrode with a standard BNC connector.
CARACTERíSTICAS DEL PRODUCTO
Enhanced Accuracy & Precision
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.?
