Deskripsi

Mini pH Controller HANNA BL931700

  • 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.”
  • Analog Output Communication
  • The BL931700 features a 4 – 20 mA analog output for connection to a data logger, chart recorder, or other device.
  • Matching Pin Connection
  • An included matching pin option helps protect the sensor from ground loop effects that may lead to erratic readings or system damage.
  • Fuse Protected Dosing Contacts
  • The mini controller is protected for up to a 2A load from the connected pump or device.
  • Easy Peripheral Connection
  • Quick-connect terminal blocks provide for easy connection to power, communication, dosing control, or sensors.
