Oakton WD-35640-30 Waterproof DO 450 Meter with Probe
Link Gulf WD-35640-30 / Cole-Parmer EW-35640-30
Affordable optical RDO technology reduces maintenance time and costs
The RDO 450 meter uses optical measurement technology, offering fast response times and long-term stability with minimal maintenance. Plus automatic temperature compensation (ATC), barometric pressure compensation, and salinity correction to further ensure measurement accuracy. The large, backlit LCD lets you view % saturation or mg/L (ppm) simultaneously with temperature.
Rugged, IP67-rated waterproof housing makes the meter ideal for plant or field testing. Additional features include a ready (stability) indicator, smart averaging, hold function, calibration alarm, and battery-life indicator.
Perform data logging with manual or timed collection of up to 500 data sets with real-time clock time/date stamp. Order optional data cables for USB and RS-232 connectivity.
