##Orion Star A216 pH/RDO/DO

Features and Benefits

• Combined pH meter and dissolved oxygen meter integrated into a user-friendly system
• Measure pH, mV, relative mV or ORP with temperature on channel 1 and dissolved oxygen in percent saturation or mg/L with temperature using RDO optical DO sensors or polarographic DO sensors on channel 2
• Quick readings of individual measurements on a large display with the option to switch to split screen to view multiple measurements simultaneously
• Perform up to 5-point pH calibration using automatic buffer recognition of NIST or DIN buffer groups with the option for manual entry of custom buffer values and calibration editing to adjust individual points without a full recalibration
• Calibrate dissolved oxygen using water-saturated air, air-saturated water, set value (Winkler titration), and zero point
• Automatically compensates DO readings using ATC temperature, manual input of salt content, and manual barometric pressure
• Informative, backlit, graphic display that is easy to read with clear screen instructions, simplifying operation
• Record critical measurements with stability indicator and optional reading modes – “Auto-Read” maintains a stable reading, “Continuous” shows changes with hold option, and “Timed” stores data at specific intervals
• Eliminate the need for magnetic stirrer bars using a meter-controlled stirrer sensor (part no. 096019) for uniform mixing solutions
• Datalog stores up to 2000 measurements with date/time and options for sample ID and user ID
• Calibration log stores the last 10 calibrations
• Non-volatile memory ensures your data and settings are protected even during power loss
• Orion Star Com software facilitates data transfer to a computer via USB or RS232 connection
• Flexible power options with a universal adapter or AA batteries
• IP54 enclosure is water- and dust-proof and can be wall-mounted if countertop space is limited
• Meters are CE, TUV 3-in-1, and FCC Class A certified with a 3-year exchange warranty
