ATEX certified transmitter with data logger. Optionally with LTE modem and sampling function.

ATEX certified
for zone 1/2



  • plug and play connection of up to 4 Mettler Toledo ISM sensors (such as pH, ORP, Te, conductivity, CO2...) in parallel.
  • additional digital EOG sensors can be used for level and VOC measurements.
  • 2x passive/active 4-20mA inputs
  • RS 485 as master/slave function (e.g. for a Mettler Toledo load cell)
  • internal 4 GByte memory card allows logging of data over a long period of time
  • the integrated logger allows the evaluation of historical measurement and sampling data. with the optional LTE modem, these can also be transferred wirelessly via e-mail, FTP and directly to the Ori Mcloud.
  • with the optional sampling module, the transmitter can also be expanded to an automated sampler
  • ATEX certified for zones 1 and 2, sensors may even be operated in zone 0


  • NEMO logs all relevant data, such as measured values, sampling dosages and further service data in the internal 8GB data memory
  • When using the ISM sensors, further characteristic data such as DLI (dynamic life), serial numbers...are stored

4G / LTE

  • The NEMO product range can be optionally supplemented with a 4G (LTE) modem
  • ATEX certified for II 2G IIB T4 it can be used to communicate within Zone 1, directly from sewage shafts or other hazardous areas
  • Data can be transferred periodically or event-driven via e-mail, FTP or in parallel directly to the Ori Mcloud
  • Sampling can be started or operating states queried via SMS

RS 485 Modbus/RTU

all logged data such as:

  • Sensor readings
  • Sampling log data
  • Alarm values
  • Thermostatization characteristic values

can be read out via corresponding registers through RS 485 Modbus/RTU interface

Display unit

  • large OLED display
  • Operation with magnetic pen
  • Scratch and shock resistant safety glass
  • LED status bar
  • See the status from a distance
  • Check representative sampling-only when LED is green, laboratory analysis is worthwhile
  • RS485 & USB
  • Bluetooth

More than just a display unit

  • Mobile 8GB USB Storage - Sampling and measurement data can be read on-site at the instrument and transferred to the display memory
  • Transfer data to office computer via USB or Bluetooth connection
  • Display unit can also be installed up to 30m away from the device. Also important when installing the devices in the sewage shaft.
  • Hot swap capable even in the Ex area- with only one display can be operated several devices

Atex certified premium transmitter

  • 10-channel measuring device with logger function for the measured variables pH, ORP, conductivity, oxygen, temperature, level, weight, water detection sensors, temperature and pressure sensors of the CEX1/2 cooling units...
  • for monitoring processes even in hazardous areas of zone 1+2.
  • sensors often even zone 0
  • offers various trigger possibilities for event proportional 4.0 sampling
  • in shock-resistant plastic housing or in stainless steel design in combination with the NEMO dosing module
  • mobile with battery unit or stationary as wall- or pole-mounted unit or integrated in the NEMO sampler
  • Data transmission via RS 485, USB, Bluetooth or integrated 4G (LTE) modem


Intelligent process sensors

Plug and Play connection of up to 4 digital ISM Mettler Toledo or EOG sensors to the NEMO transmitter in parallel possible.

With predictive maintenance and sensor diagnostics
The predictive maintenance features of the NEMO Transmitter provides diagnostic functions for the Mettler Toledo ISM sensors, such as a dynamic life indicator (DLI). This information reduces the need for maintenance as well as the risk of unplanned downtime due to unexpected sensor defects. You will be informed when maintenance or calibration of the ISM sensors is required.
