pH-meter ATEX Mod. 904 eX

With ATEX approval for measurements up to zone 0/1

Mod. 904 eX pH, the world's only portable device for pH measurement with ATEX approval for measurements up to zone 0/1. Ideal for applications in the process industry.

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.

For the first time, this model enables direct onsite testing of process measuring points. It is compatible with almost all analog and Memosens process sensors.

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.

Features

  • A sensor quiver protects the sensor from damage and drying out
  • The high-performance polymer housing ensures low water consumption and high impact resistance
  • Over 1,000 hours of measurement with a single set of batteries (4x AA)
  • Data logger with 5,000 values
  • Micro USB port and Paraly SW 112 software
  • Memosens sensors and analog pH sensors can be used on one device (e.g flat-membrane sensors)
  • The mineral glass display is perfectly readable even after years
  • Application in hazardous locations for measurements up to Zone 0/1 (cCSAus planned)
