Description
Cole-Parmer® Oakton® PD 450 Waterproof pH/DO Handheld Meter with Probes, WD-35632-30
Features:
- Optical DO sensor eliminates the need for costly and time consuming changing of membranes and electrolyte and provides fast, stable measurements
- IP67 waterproof and dustproof rating is ideal for field measurements
- Automatic temperature compensation (ATC)
- Provides barometric pressure and salinity correction for DO measurements for added accuracy
- Manual or automatic data log with memory for 500 data sets complete with real-time date/time stamp that can be easily downloaded via USB or RS-232 cables (purchase separately)
- Built-in stand for hands-free measurements for use on a benchtop
- Large, backlit LCD lets you view pH, mV, % saturation, or mg/L (ppm) simultaneously with temperature
- Ready indicator
- HOLD function
- Calibration alarm
- Smart averaging
- Battery-life indicator
