Portable Conductivity Meter Thermo Orion Star A3220

The Thermo Orion A322 portable battery-operated waterproof conductivity meter rises to the most demanding field applications to deliver the most advanced performance of any portable meter. Four AA batteries, included with the purchase of the A322, provide over 800 hours of continuous operation so the instrument is ready when needed, where it is needed most. The meter displays reliable conductivity, TDS, salinity, resistivity, and temperature readings on a large backlit LCD screen and automatically locks on stable readings. A320 Orion Star series portable meters provide the highest available storage capacity for data points with timestamps, which can be conveniently uploaded to a PC via RS-232 USB ports and the meter. Automatic calibration or 1 to 5 points makes manual instrument setup simple, while icons provide quick updates on battery life, electrode status, and calibration information.Five reference temperature options are available to provide accurate data under all conditions. The simple button layout and display messages also assist with calibration and explain the configuration menu options.
