About This Product
■pH controller with dual output
The HI 8711 has dual outputs, allowing you to manage acid and alkali dosing separately. Self-diagnostic features are also included to verify offset and slope calibration, as well as electrode contamination and deterioration.
■Main features
・Input & output function
The instrument accepts direct input from a pH electrode or a transmitter via a 4-20mA input. It also provides ±5V power to the input/output terminals for amplified electrodes. Additionally, output settings are available for connecting a recorder or PLC. (Choose from 0-20mA or 4-20mA)
・Functions such as overtime control function and hysteresis setting
■Accessories
