DESCRIPTION:
The BL931700 is the smallest panel mounted pH controller around. It's small size allows installation close to your aquarium and the single set point relay output permits control of a CO2 Injection System for maintaining your desired pH levels.The BL931700 accepts direct input from any combination pH electrode with a BNC Connector and provides measurements from 0 to 14 pH with a resolution of 0.01 pH. This unit also transmits a 4-20mA output current that is directly proportional to the input signal but is independent of changes in load or cable capacitance. Calibration is performed with two trimmers for offset and slope adjustments. Some of the BL931700 features include:
