pH meter converter "HDM-135A type/HDM-136A type"
Easy operation with the waterproof switch below! A pH meter converter that allows arbitrary setting of transmission output DC 4-20mA with a width of 2pH or more.
The "HDM-135A model (2-wire type) / HDM-136A (4-wire type)" is a compact and robust pH meter converter (transmitter) designed for on-site installation, featuring simple functions and easy operation in an aluminum case. It is available in a 2-wire type (DC 24V power supply) and a 4-wire type (AC-free power supply), and it transmits an output of DC 4-20mA. If normal standard liquid calibration cannot be performed, it will display messages for zero or slope abnormalities, or instability issues. 【Features】 ■ Changeable pH transmission output range ■ One-touch automatic calibration ■ Automatic determination of pH electrode condition ■ pH measurement value shift ■ Glass electrode crack detection *For more details, please refer to the PDF document or feel free to contact us.
