Compact LMA conductivity meters: analogue or Modbus

The LMA series combines a conductivity transmitter and measuring cell in a compact unit for measurements in liquids. Select the version that suits your application and the interface of your control system.

Select the right LMA version

• LMA-LED: LED indication, audible signal, switching output and 0(4)...20 mA current output.
• LMA-I: two 0(4)...20 mA current outputs; the LMA-I 1000 version is also listed.
• LMA-S: two switching or frequency outputs.
• LMA-MODBUS: digital communication via RS-485 and Modbus RTU.

The measuring range, cell constant and measuring cell material depend on the selected version. Technical specifications and available options are listed on each product page.
