Overview

The Orion A322 Portable Conductivity Meter is the perfect option if advanced conductivity, TDS and salinity measurement are required on location. The large backlit graphic LCD clearly displays conductivity/TDS/salinity resistivity and temperature.

The Star A322 conductivity meter features extras such as stability and averaging options with additional options allowing for laboratory accuracy in any location. Linear, non-linear, nLFu or EP curve options are available with reading reference temperatures of 5, 10, 15, 20 or 25°C for advanced accuracy. There is the option to choose either practical salinity or natural sea water curves to gather salinity readings. Linear or ISO/EN 27888 curves for TDS are also available. Additional features are user ID and calibration points, electrode status, sample ID, time and date. Multilanguage options in English, Spanish, French, Italian, German and Chinese are standard along with selectable cell constant allows for use with 2 or 4 cell conductivity cells.

The Orion A322 Portable Conductivity Portable Meter has the capacity to hold up to 5000 data points logging time and date, the AUTO-READ™ feature locks stable readings and the ready alert indicator highlights when readings are stable. Timed reading records data at specific time intervals.

Standard features with the A322 Portable Conductivity Meter include IP67-rated housing, waterproof protection, and the ability to run on batteries which provide over 800 hours of operation or through a universal power adapter which can be purchased separately. Data is easily transferred and up-to-date software can be sought using the USB and RS232 ports as well as data analysis software.

The Orion A322 Portable Conductivity Meter is covered by a 3 year replacement warranty.
