Portavo 904 X

Multiparameter portable with ATEX approval


 The world’s only portable device with Memosens technology for liquid analysis with ATEX approval for measurements up to zone 0/1. Ideal for applications in the process industry.

The robust and chemical-resistant housing even survives the standardized drop test from 1 meter onto concrete. High-contrast LCD with scratch-proof mineral glass screen can still be read perfectly after many years.

 More than 1,000 hours of measurement are possible with one set of batteries (4xAA).

 Data logger entries can be shown on the display using an extensive recorder function. The standard micro USB interface enables:

  • connection to a PC
  • software updates

The data logger records up to 10,000 values.
The included Paraly SW 112 software enables easy management of recorded values.
