The DO 450 meter uses optical measurement technology offeringfast 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 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.
