Oakton™ Waterproof PD 450 Portable pH/DO Meter

The PD 450 meter uses optical measurement technology offering fast response times and long-term stability with minimal maintenance for dissolved oxygen measurements.

• Optical DO sensor eliminates need for tiresome membranes and solutions
• Durable waterproof and dustproof design with IP67 rating makes this meter ideal for plant or field testing
• Large, backlit LCD to view pH, mV, % saturation or mg/L (ppm) simultaneously with temperature
• Automatic temperature compensation, barometric pressure compensation and salinity correction ensures DO measurement accuracy
• Memory for up to 500 data sets with USB or RS-232 output to PC
• 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
• Built-in stand allows for easy benchtop use
