WMDO1001-PN DO Meter

The WMDO1001-PN dissolved oxygen meter is a panel-mounted controller for continuous monitoring of DO in industrial water and wastewater. Paired with the WSDO4001 electrode, it measures dissolved oxygen at ppm level from 0 to 19.99 mg/l, or 0 to 199.9% saturation, with ±1.5% FS accuracy. A microcomputer stores the parameters needed to calculate and compensate the measured DO value, with settings such as elevation and salinity, and automatic temperature compensation covers 0 to 60 °C. Simplified functions keep the cost down without reducing measuring performance, while the backlit LCD, isolated 4–20 mA output and dual relays make it straightforward to integrate into DO test and control loops.
