Orion Star™ A326 pH/Dissolved Oxygen Portable Multiparameter Meter, Thermo Fisher Scientific (CAT#: STEM-LE-1833-LC)

Use the Thermo Scientific™ Orion Star™ A326 pH/Dissolved Oxygen Portable Multiparameter to test samples anywhere. The rugged and reliable test tool is one of the best choices for every sample every day, anywhere.

DO Measuring Range:0 to 90 mg/L; 0 to 600 % saturation
Measurement Mode(s):pH, mV, Polarographic DO, RDO, Temperature
Measurement Resolution:0.1 pH, 0.01 pH, 0.001pH, 0.1 mV, 0.01, 0.1 mg/L; 0.1, 1 % saturation, 0.1 °C
pH Range:-2.000 to 20.000 pH

A large backlit graphic LCD display provides the information you need; it can display the results of a single pH / mV / RmV or dissolved oxygen saturation or concentration percentage change with temperature, or all results at once
Other useful information includes electrode status, time, date, sample ID, user ID and calibration point
The meter has simple language screen prompts, easily selectable updated soft keys, and a multilingual interface that supports English, Spanish, French, Italian, German, and Chinese
Thermo Scientific™ AUTO-READ™ locks the stable reading on the screen. When the reading is stable and the timed reading collects data within a specific time interval, the indicator will remind the user
The meter can provide pH calibration up to five points and automatically recognize USA/NIST™ and DIN buffers
The user can make pH calibration errors without modifying the calibration without having to recalibrate completely
The meter can provide accurate dissolved oxygen results through automatic temperature, manual salinity and automatic/manual pressure correction
The meter can calibrate the DO using water saturated air, air saturated water, Winkler titration or zero calibration
Non-volatile memory can hold up to 5,000 data points with time and date stamp
USB and RS232 ports and free data analysis software make it easy for users to transfer data and keep the instrument software up to date
Four AA batteries (included) can provide more than 800 hours of operation time; purchase a universal power adapter (sold separately) to use AC power
The instrument is portable, waterproof, and the protection level is up to IP67, which can be carried anywhere
The instrument has a three-year replacement warranty
