The Orion A321 Portable pH Meter is capable of giving advanced readings when working on location. The informative display shows pH/mV/RmV and temperature along with electrode status, time, date, sample ID, user ID and calibration points.
The pH meter has the capacity to hold up to 5000 data points time and date stamped. Up to 5 point pH calibration which automatically recognizes USA/NIST and DIN buffers.
Additional advanced features are stability and averaging options which give further options allowing for laboratory results whilst on site. AUTO-READ locks stable readings on screen and the ready indicator highlights when readings are stable. Timed data gatherings enable data to be collected at specific time intervals. Multilanguage options allow the meter to read in English, Spanish, French, Italian, German and Chinese.
Standard features include easy data transfer and software updates by using the USB, RS232 ports plus the complimentary data analysis software. Waterproof, IP67-rated housing and the ability to run from batteries which give 800 hours of power or though a universal power adapter sold separately allows for this meter to be used anywhere and fully portable.
