Fail Safe Alarm System
Hanna’s exclusive Fail Safe Alarm System protects against problems caused by power supply failure or signal interruption, which are typical risks in industrial environments. An alarm condition is indicated by a red LED, located directly on the front panel of the controller.
Overtime Dosing Protection
The pH Controller HI8711 Hanna Instruments incorporates adjustable overtime dosing protection from 5 to 60 minutes. If dosing exceeds selected time, the alarm will be triggered and the dosing contact will deactivate. This feature can be activated or deactivated.
Output and Input Connections
Each model accepts either a direct input from a pH or ORP electrode or from a transmitter through 4-20 mA input. The instrument also provides ±5V power output and input terminals for amplified electrodes. Moreover, you can choose the output configuration for connecting a recorder or a PLC, between 0-20 or 4-20 mA.
Self-Diagnostic Test
Memiliki fitur Built-in autodiagnostic, sehingga memudahkan teknisi dalam melakukan troubleshooting jika ada masalah.
Matching Pin Connection
Supports potential matching pin connection to avoid typical problems caused by grounding loop currents, such as progressive damage of the electrode, fluctuating measurements, and poor process regulation.
Robust Design
A removable, transparent splash-proof cover protects the front panel.
