pH/ORP meter converter
PE-51

Simple 4 wire type pH/ORP meter converter

It is a measurement converter of the DC24V type for on-site use.

Because of its waterproof construction, it can be installed directly,

and since its power supply and output line are provided separately,

no equipment for taking out transmission output is required.

Advantages

・With automatic calibration functions, pH calibration can be done easily.

・The buffer solution can be chosen, such as pH6.86 (JIS) and pH7.00(USA), etc.

・With a large liquid crystal display with backlight, the indication is easy to see beyond comparison.

・Since the power supply is DC24V, wiring for the power supply and transmission output is completed

　by just using one 4-core cable.

・The insulation transmission output DC4 - 20mA is provided as standard specifications.

・Attachment tools are also provided that enable the converter to be mounted onto a pole, control panel, tank, etc. easily.

Applications

・Remote control of pH/ORP measurement, etc.
