Dear reader of our SOMMER newsletter,

We are pleased to send you a further issue of our newsletter. We invite you to take a short moment to read about our latest product innovations, such as the new MRL-7 data logger or the revised SPA-2 system.

Maybe we will see you at one of the next upcoming trade fair events where we also participate or you want to check out our social media channels... More details below!

All the best,

Your SOMMER Messtechnik team.


NEW: MRL-7 Data Logger

NEW: MRL-7 Data Logger


The new MRL-7 perfectly completes the SOMMER data logger family

The MRL-6, which was launched in 2016, has got a "bigger" brother. After only a short development time the MRL-7 enters the market: a new, very robust and weather-proof data logger with integrated remote data transmission. The acquisition, processing, storage and transmission of measured values ​​as well as remote access via IP-call have thus become even easier.

A number of advantages speak for the smart, new logger:

  • Integrated 2G/3G (optionally 4G) modem for remote data transmission
  • Optimised, very energy-saving operation ideal for data acquisition in environmental measurement technology and in the absence of any infrastructure
  • Self-sufficient operation thanks to battery supply (with internal battery for the MRL-7B)
  • Integrated solar charge controller - possibility to connect a solar module
  • Weather-proof housing, temporarily immersible (IP 67)
  • Backlit display, comfortable operation
  • Interfaces: sensors via SDI-12 and RS-485; communication via RS-232, USB and Bluetooth
  • Notification management (E-mail and/or SMS messages) for limit value exceeding/deceeding
  • Compact, robust and reliable

Areas of application

The new MRL-7 is particularly well suited for data collection and transmission in outdoor applications. Due to its powder-coated, watertight housing, no additional switch cabinet is needed. The robust logger is therefore the ideal solution in the fields of environmental monitoring technology and for remote, self-sufficient installations without a permanent power supply. But also many other, smaller or compact measuring sites and applications in hydrology, meteorology, water management, waste water treatment or flood protection can be managed very well.

SPA-2 System

Snow Pack Analyser SPA-2

Snow-Pack-Analyser, system 2.0
New sensor generation with valuable improvements

Increased ease-of-use and additional features such as improved connectivity for external sensors or the SDI-12 interface integration make the new SPA, the SPA-2, an even more valuable snow measurement system.

The unique SPA strap sensor together with the control and analysing unit now provides even more reliable information on the condition of the snow pack and allows qualified forecasts on the expected water run-off during the snow melting process.

Typical applications are hydro-meteorological installations, flood protection, water management, hydropower plants, agriculture, skiing resorts or research facilities.
