The Portavo 904 X is an invaluable multi-purpose tool for any analyzer or lab technician. It is the only portable meter on the market with hazardous area approvals. Designed for use inside of plant operations as well as in the shop or lab, this portable meter, with a connected sensor, measures pH, ORP, conductivity, or oxygen. This versatile instrument provides portable field measurements, sensor diagnostics, data logging, and offline sensor calibration.

Simple, Intuitive, and Informative

Intuitive menu navigation, the automatic sensor calibration function, and easy-to-understand sensor diagnostics make the Portavo 904 X simple to implement in any instrument/analyzer shop or lab. The LCD-Segment display is readable in direct sunlight and provides critical sensor information such as:

• Sensoface: sensor status at a glance
• Sensor calibration data

Automatic and manual calibrations are possible using the Portavo 904 X with up to 3 points. Automatic calibrations use pre-installed buffer tables, while manual calibrations can be done with user-defined buffer tables. There is no need to re-calibrate the Portavo. Because it is a digital meter, there is no drift.
