DO500 Dissolved Oxygen Transmitter Description
This isolated output 4-20mA industrial transmitter is a sturdy microprocessor-based instrument that measures dissolved oxygen and temperature and transmits the dissolved oxygen output via a two-wire power supply loop. This transmitter has many user-friendly features - all of which are easily accessible via the water resistant membrane keypad. Ideal for connecting to a PLC for advanced control systems, the transmitter can also be connected to a recorder for a low-cost documentation system. The instrument housing is designed for panel or wall mounting.
