The Lovibond® MD 100 2in1 Pool Photometer is a multi-parameter instrument which allows for fast and easy measurement of pool water quality. Easily test for Free, Total and Combined Chlorine as well as pH with Lovibond® Tablet or Liquid reagents.
Ideal for poolside testing, the MD 100 comes ready to use with all of the reagents and accessories required for testing.

The MD 100 has several key features that make it a favorite among users.

  • Waterproof Design
    The IP 68 design of this instrument ensures that the MD 100 remains water tight for up to 1 hour at 0.1 meter.  Don’t worry about dropping the instrument into a body of water – it floats!
  • Accurate, Reproducible Results
    The optical system of the MD 100 utilizes LEDs and interference filters which quickly gives you results that you can be confident in.
  • User Calibration Mode
    A one-point calibration is possible.  Additionally, all MD 100 instruments have the ability to display readings directly in ABS or %T units.
  • One-time-Zero Function
    Don’t waste time waiting for your instrument to Zero after each test.  When testing a new sample, zero the instrument once and all subsequent tests of that sample do not require you to re-zero the instrument.
  • Automatic Data Storage with Transfer Capabilities
    The MD 100 automatically stores the last 16 readings with time and date stamp.  These results can be transferred to a spreadsheet using the IRiM accessory.
  • Ergonomic Design
    Whether you’re using the MD 100 out in the field or in the lab, the design of the instrument  makes it easy to handle and view the display.   If you’re using the instrument in the lab, the rubber feet on the bottom of the housing eliminates the need for two hand operation or to chase your instrument around the workbench.
  • Factory Programmed
    All MD 100 instruments are supplied ready to use with up to 14 calibration curves.  All you need to do is select the test you need, prepare your sample and test!
  • Scroll Driven Menu System
    The simple interface allows you to quickly reach the test you need.  When the instrument is turned on, it will automatically display the last test used.
