Multi meter Portavo 904 X Multi

The world's only portable device for liquid analysis with ATEX approval for measurements up to Zone 0/1. Ideal for applications in the process industry. For the first time, Portavo enables direct on-site testing of process measuring points. It is compatible with almost all analog and Memosens process sensors. Memosens sensors with different parameters can be checked without changing the sensor cable.
  • The new MemoLog function allows the user to log calibration data from various Memosens measuring points, which can then be easily transferred to a computer via the standard USB connection. The Paraly SW 112 software enables user-friendly management of all recorded data
  • A sensor quiver protects the sensor from damage and drying out
  • The high-performance polymer housing ensures low water absorption and high impact resistance
  • Over 1000 hours of measurement with a single set of batteries (4 x AA)
  • Data logger with 5000 values
  • The mineral glass display is perfectly readable even after years
  • The world's only portable device for liquid analysis in hazardous locations
