LTH MXD70 Analyser

LTH MXD70 is an analyser for LTH’s range of analytical probes.  A multi-input device, the LTH MXD70 can accept pH/redox, conductivity, dissolved oxygen, suspended solids and turbidity probes.  Of modular design, up to 3 inputs can be connected to the analyser at once – including a 4-20mA from another (even non LTH) instrument.  The analyser is available in 2 mounting options

  • LTH MXD73, compact 96DIN panel mount option, with IP66 front face
  • LTH MXD75 surface or pipe mount option, also IP66 ingress protection

Both models include a clearly visible 95mm QVGA backlit LCD display.  The display is easily configurable and will show up to 3x measurement parameters.  Additionally, an SD card drive can be used to save configuration and easily upload to duplicate analysers.  This is a significant time saver, especially useful for stock holding and replacements.
