Modular Analyser (TT-MA)


Create a fully functional multi-parameter analyser by selecting any combination of measurements that you need from our analytical modules. Compact in size, these modules incorporate a fully equipped analyser with high-quality circuitry that provides stable, low noise measurement. The ability to combine analytical modules with a vari­ety of expansion modules creates a powerful array of analysing hardware.

Analytical modules:

  • pH/ORP
  • Dissolved oxygen
  • Conductivity

Function modules:

  • DSS display
  • Relays
  • Temperature
  • Datalogger



  • Simple and precise calibration functions
  • Easy to read bright LED display visible in direct sunlight
  • Galvanic isolation between all inputs, power and analogue output
  • 3-button operation with no complex codes to memorise for most day-to-day tasks
  • Housed in a weatherproof IP65 or optional NEMA 4X CSA/ UL rated enclosure
  • Up to 8 modules per enclosure

Choose your measurement modules and combine them with a variety of function modules to create a powerful array of analysing hardware.

Suffix Measurement Modules Description
PH-PD pH/ORP Proprietary Digital A measurement module for pH and ORP Smart Digital Sensors. Provides 4-20mA output or Modbus RTU. Supports 2 and 3 point calibrations, plus auto-calibration feature. Specifically designed to interface with Proprietary Digital (PD) sensors.
PH-A pH/ORP Analogue A measurement module for conventional pH and ORP Analogue Sensors. Provides 4-20mA output. Supports 2 and 3 point calibrations. Specifically designed to support conventional preamplifier sensors (-AP). Also available for non-preamp sensors (-A).
CON Conductivity Supports most any cell constant (K), including but not limited to 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1.0, 2.0, 3.0, 5.0, 10.0 & 20.0. Effective calibrated cell constants are supported from K=0.005/cm all the way up to K=34.0/cm and anywhere in between.
DO Dissolved Oxygen A measurement module for Dissolved Oxygen. Displays and outputs the concentration of dissolved oxygen in ppm, % saturation units, as well as the process temperature.
Suffix Function Modules Description
DSS DSS Display Provides local display and isolated, scalable and reversible 0-20mA or 4-20mA output of any measured parameter from any mating DSS sensor. Temperature and absolute mV can be displayed for pH/ORP/DO DSS sensors. Temperature and raw conductivity can be displayed for Conductivity DSS sensors. Compatible with a Hot-Swap sensor maintenance regime
REL Relay Fully configurable by the user as to control mode and variables for each control algorithm. The tight integration between the Relay module and TT-MA measurement modules software makes configuration and scaling simple and easy for any local control requirements of the pH, ORP, Dissolved Oxygen, Ion Selective or Conductivity parameters.
TEM Temperature Adds a scalable analog output for Temperature to any measurement module (ie pH/ORP, CON, DO). This expansion module can be used to add a temperature output at any time, before or after commissioning.
DAT Data Allows for data logging of up to 63 each Modbus digital inputs from any mix of TT-MA-pH, TT-MA-CO and TT-MA-DO modules as input nodes. Note that the measurement module must be ordered with MODBUS output.
