This rugged, waterproof portable meter is designed for a wide range of pH, ion concentration, conductivity, dissolved oxygen and temperature testing and field applications. It can be used in the most demanding locations thanks to its IP67-rated housing. The meter offers three measuring channels allowing users to measure pH, conductivity and DO simultaneously or view each channel separately.
- Up to five point pH calibrations with calibration editing option that allows individual points to be fixed without a full recalibration
- Automatically compensate dissolved oxygen readings using ATC temperature, manual salinity input and built-in barometer for barometric pressure readings
- Informative, easy-to-read backlit graphic display with clear onscreen instructions simplifies operation
- Measurement stability indicator and selectable read modes – Auto-Read holds a stable reading, Continuous shows changing readings with hold option and Timed logs data at specific intervals
- Data log collects and date/time stamps up to 5000 measurement sets with optional sample ID and user ID
- Calibration log stores ten most recent calibrations
- Orion Star Com software facilitates data transfer to a computer via USB or RS232 connections
Measure pH, mV, relative mV or ORP with temperature on channel one and measure dissolved oxygen in percent saturation or mg/L with temperature using RDO optical DO probes or polarographic DO probes on channel two.
Automatically compensate dissolved oxygen readings using ATC temperature, manual salinity input and built-in barometer for barometric pressure readings. Transfer single, range or all data points to printer or computer.
Auto-ranging conductivity values offer consistent readings across entire measurement range without need to recalibrate. Use linear, non linear, EP (USP) or off conductivity temperature compensation with 5, 10, 15, 20 or 25 °C reference temperatures. 3-years replacement warranty.
The kit additionally includes: 8107UWMMD ROSS Ultra Triode gel filled epoxy-body pH/ATC electrode (3 m cable), 013010MD DuraProbe 4-cell (K=0,475) epoxy-body conductivity sensor (3 m cable), 087010MD RDO optical DO sensor (3 m cable), calibration sleeve and guard, Orion pH 4/7/10 buffer pouches (10 packs each), ROSS electrode storage solution (475 ml), Orion rinse solution pouches (10 packs), Orion 1413 µS conductivity standard pouches (10 packs), Orion Star A series portable meter armor and Orion Star A series hard-sided field case.
