Monitoring & Control Systems

Monitors and Handheld Meters

At DSA we offer a full range of monitors and controllers for parameters such as pH, ORP [Redox], EC [Conductivity] Free chlorine.

We also offer complete systems mounted on panels or skids that will include the monitor/controller electrode flow cell and dosing pumps.

We also stock a comprehensive range of controller based dosing pumps i.e the controller function is incorporated into the dosing pump

 

BLUELAB

Bluelab is a high quality brand aimed at the horticulture sector and offer tank or inline pH and EC monitoring, as well as a rnage of heandheld meters and pens.

ETATRON

In our Etatron range we offer a comprehesive range of controller from 1 to 4 measures per instrument, these can be pH, Rx and/or Cl in any combination, we also offer pH and EC combination controllers. We also stock a full range of accessories in including a choice of electrode, electrode holders and cells, calibrations solutions and electrode maintenance kits.

Econtrol

BT Series - MA/AD Solenoid Dosing Pump

The eControl series of controllers have been designed and developed to be used in wellness centres, domestic and public swimming pools.
The controllers use galvanic isolated micro-processors protecting the measured readings from the application environment.

The principal functions performed by the eControl are:

  • Sensor calibration: 0.00 ÷ 14.00 “pH”, -1000 ÷ +1400 mV “Redox”, 0÷2, 0÷20, 0÷200 ppm (Cl), 0÷2, 0÷20, 0÷200 ppm (Ion-selective sensor of for a specific chemicals).
  • Temperature control definition: automatic (connection to PT100 sensor) or manual (default 25°C)
  • 2 set points for each measure input.
  • Type of intervention (direct or inverse).
  • Hysteresis
  • ON/OFF or proportional activation mode
  • Delay time of the pump activation
  • MAX alarm, for maximum measure.
  • MIN alarm, for minimum measure.
  • Over alarm, indicates an overdose situation. This is activated when the defined set point value is not reached in a predetermined time
  • 4 - 20 mA output, galvanically isolated.
  • Relay output for signalled alarm status.
  • Optional - eControl with double measurement ranges that are independently configurable.
Eselect B4

eSelect B4

In reference of the last technology in electronic field we have built the B4 controller to measure the main parameters in the water treatment applications. It is possible to connect the new controller to an Ethernet LAN to control all parameters and storage all data. We have decided to use a 7” coloured display touchscreen to improve the view, the user-friendly setting and display the graphic of the time-measure.

The main technical characteristic of the new B4 are the following:

  • 3 measure channels (4 on request), settable separately by the user: pH, RX, Cl2, Cl tot.
  • Temperature measure
  • Automatic filter washing output
  • No. 2 auxiliary outputs activating by a weekly/daily timer
  • No.1 input water meter
  • No.1 Ethernet RJ45 (LAN) connection
  • No.1 USB to update firmware or to download data
  • Power supply 100-250 Vac or 12-30V dc
