Self-testing Diagnostics
Built-in auto-diagnostic functions to enable the user to check and troubleshoot any malfunctions. The functions are made via front panel keys to isolate the cause of malfunction whether it is due to pH electrode contamination, internal offset circuit or the amplifier circuit.
Recorder Terminals
To enhance troubleshooting and the ability to record data while monitoring, simply attach a recording device to the instrument’s 4 to 20 mA output contacts, conveniently located on the front panel, to obtain a copy of the results on demand.
Easy Installation
HI8512 is provided with membrane keypads on the front panel, large display, and auto-diagnostic functions to check pH electrode and instrument status.
Easy pH Electrode Connection
Allows for quick and easy connection to any ORP meter or transmitter.
Protective Cover
A removable, transparent splash-proof cover protects the front panel.
LED Indicators
LED indicators identify the controller mode.
