ORION STAR A329 PORTABLE METER KIT

The waterproof, battery-operated Thermo Orion Star A329 portable pH/ ISE/ conductivityRDO/ DO meter stands up to the most demanding field applications to deliver the most comprehensive package and advanced performance of any portable meter. Four AA batteries, included with purchase of the A329, provide over 800 hours of continuous operation so the instrument is ready when it' s needed, where it' s needed. The meter displays reliable pH, mV, RmV, ISE, conductivity, TDS, salinity, resistivity, dissolved oxygen concentration, dissolved oxygen percent saturation and temperature readings on a large, backlit LCD screen and automatically locks in stable readings. Both Orion polarographic and RDO optical DO probes are compatible with the meter, as well as the extensive line of Orion pH, ISE, and conductivity electrodes. Orion Star A320 series portable meters provide the largest storage capacity available for time-stamped data points, which can be conveniently uploaded to a PC through the meter' s USB and RS-232 ports. Automatic or 1 to 5 point manual pH/ ISE and conductivity calibration and a variety of DO calibration options make instrument setup simple, while icons provide quick updates on battery life, electrode status and calibration information. The simple button layout and on-screen messages also assist with calibration and explain setup menu choices. AUTO-READ function alerts user and locks on-screen readings when stable Up to 5 point pH/ ISE and conductivity calibration with calibration editing Automatic recognition of USA/ NIST and DIN buffers Advanced ISE features such as timed end point, linear point-to-point, non-linear selectable auto-blank and low-concentration range stability Selectable cell constant for use with 2- or 4-cell conductivity cells Selectable reading reference temperatures of 5, 10, 15, 20 or 25 C to increase conductivity accuracy Includes standard practical salinity curve for salinity readings, linear or ISO/ EN 27888 curves for TDS Accepts Orion polarographic and RDO optical probes Automatic temperature compensation, manual salinity compensation and automatic or manual barometric pressure compensation DO calibration options include water-saturated air, air-saturated water, Winkler titration and zero point Easy to recall calibration slope data for procedure checks Non-volatile memory holds up to 5000 data points USB and RS-232 ports to upload data and update included data analysis software Universal power supply or battery power option Includes ( 4) AA batteries to provide over 800 hours of operation Universal power adapter ( sold separately) runs meter on AC power Multilanguage interface supports English, Spanish, French, Italian, German and Chinese IP67-rated waterproof housing ( can be immersed up to one hour with no water incursion)
