The waterproof, battery-operated Thermo Orion Star A325 portable pH/conductivity meter stands up to the most demanding field applications to deliver the most advanced performance of any portable meter. Four AA batteries, included with purchase of the A325, 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, conductivity, TDS, salinity, resistivity, and temperature readings on a large, backlit LCD screen and automatically locks in stable readings.

Thermo 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 calibration makes 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.
