Multi-parameter meter, handheld, for ATEX areas, Portavo® 904 X Multi Set

This explosion-proof, multi-parameter meter has been specially designed for employment in potentially explosive areas. It is suitable for daily routine pH, ORP, conductivity and oxygen measurements. Waterproof according to IP 66/IP 67.

Portable analyser with ATEX approval for zone 1, sensor for zone 0
Integrated cover protects the display and serves as lab stand
Digital Memosens input, allows signals to be digitised and transferred inductively i.e. via a non contact connection
With data log for up to 5000 values
Integrated sensor quiver (protective container for sensor) prevents sensor dry-out and damage
Clear glass display is easy to read, even after years of use
Automatic status check of the device and sensor; evaluation of the sensor data end calibration intervals
Memosens®: All information on sensor life are saved directly on the sensor (history of calibration, operation time, lifetime, sensor wear, SIP cycles…)

Plastic transport case.

: Meter only is supplied with USB cable but without electrodes. The set is supplied with Memosens pH sensor SE554X/1-NMSN, case, USB cable (1,5 m), Memosens cable CA/MS-001XFA-L, buffer solution, 4 AA batteries, carrying strap, factory certificate, Paraly 112 PC software, and manual. All relevant certification is supplied with the meter or can be obtained on the Knick website.
