Water analysis system – Lovibond® MultiDirect Photometer


Multi-parameter photometer for the measurement of many parameters. Ideal for laboratory use. Dual beam technology and interference filters for highest accuracy.

Description of Unit:

The MultiDirect is a contemporary, microprocessor-controlled photometer with ergonomically designed keypad and large-format graphic display. It is equipped with a wide range of pre-programmed methods based on the proven range of Lovibond® tablet reagents, liquid reagents, vial tests and powder reagents (VARIO Powder Packs). Users can also store their own methods.


  • Waste water
  • Drinking water
  • Industrial process Water
  • Scientific applications
  • Governmental and private laboratories
  • Universities and research centres


  • Dual beam technology and interference filters for highest accuracy
  • Wide range of pre-programmed methods
  • Long term stable LED’s as light sources
  • Update of new methods and languages via the internet (free of charge)
  • Memory for 100 data sets
  • Large format graphic display
  • Entire intrument, including sample chamber and battery compartment is waterproof
  • Ideal for lab use, but also battery operated for portable use
For portable use, the instrument operates with seven standard rechargeable batteries (supplied). These batteries are available all over the world and are easily changed. The integrated intelligent charge controller allows simultaneous operation of the unit and battery charging (using the supplied power pack). The MultiDirect also operates without a power pack by using alkaline manganese batteries.

N.I.S.T Traceability:

The instrument has a factory calibration, which is related to internal standards which are not N.I.S.T Traceable. The instrument may be calibrated by the user in a “user calibration mode” with N.I.S.T traceable standards

New methods:

Test methods are continuously updated to suit market requirements. You can find software updates for new methods and additional languages on the website www.lovibond.com
