The first ATEX approved portables with Memosens technology for measuring pH&ORP, conductivity and oxygen.
Safe
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.
Robust
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.
Long-lasting
More than 1,000 hours of measurement are possible with one set of batteries (4xAA).
Communicative
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.
