Thermo Orion 4-Star Portable pH/RDO Meter

Details:

Orion 4-Star pH/RDO portable meters require no membranes. Maintenance is just a simple cap replacement. This easy-to-use feature is great for measurements from effluent, aeration basins and even influent, as the sensor is not affected by color or turbidity.

• Simultaneous display of pH, dissolved oxygen and temperature on the backlit LCD

• Uses optical DO technology

• No membranes to change once‑a‑year cap replacement

• Calibrate for dissolved oxygen using water-saturated air, air‑saturated water, zero point or a custom point with Winkler titration

• Built-in barometer for automatic pressure correction for dissolved oxygen readings with option for manual correction

• pH calibration of up to 5 points with calibration alarm and automatic buffer recognition of USA, NIST and DIN buffers

• Temperature calibration capability

• Data storage for 750 data sets with time and date stamping

• RS232 port for easy data downloading and software updates

• IP67-rated meter housing and IP68‑rated RDO sensor

• Four AA batteries provide over 1000 hours of operation in

• AUTO‑READ mode

• 3-year warranty on meter and RDO sensor body

• 1-year warranty on optical cap
