With the modern design of the MD 600 we have succeeded in combining the mobility of a portable photometer with the characteristics of a modern laboratory photometer.

This unit covers all the important parameters of water analysis, from aluminium to zinc. The high level of accuracy of Lovibond® reagents and the user-friendly nature of the instrument guarantee rapid and reliable analysis of your water samples. Depending on the application, the unit will operate with tablet reagents, powder packs, liquid reagents or tube tests (16 / 13 mm).

The MD 600 operates with 6 interference filters and uses long-life LEDs as a light-source. No moving parts are involved.

The illuminated display allows comfortably reading of the measurement results even in low light conditions.

Of course, the MD 600 has a memory, in which up to 1000 data sets can be stored. The infra-red interface* enables data to be transmitted to a computer or printer (RS 232 / USB).

* available as an option : IRIM (infra-red interface module)

Delivery content: The instrument is supplied complete and readyto-use incl. 4 batteries, 3 vials ø 24 mm, 3 vials ø 16 mm, 1 adapter each for 16 mm and 13 mm vials, carrying case with water.

N.I.S.T. Traceability

The instrument has a factory calibration, which
is related to international 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 regularly updated to suit market requirements. You can find software updates for new methods and additional languages on our website at


With the help of an external mathematical program, the corresponding polynomial is created from data pairs (concentration/absorption).
A known polynomial may also be used. 25 order polynomials (y = A+Bx+Cx2 +Dx3 +EX4 + FX5) can be stored together with user-specific parameters such as wavelength, measuring range, unit and number of decimals.


This function can be used to measure 2 to 14 known standards. On the basis of the concentrations/absorption pairs obtained, the photometer will calculate a linear interpolation between the measured points. Up to 10 methods can be stored for further sample measurements.

Infra-red data transmission modul     IRiM

The IRiM (infra-red interface modul) uses modern infra-red technology to transmit measurement data from the MD 600 photometer to one of 3 optional interfaces. These interfaces can be used to connect to a PC, a USB printer1) or alternatively a serial printer2). The interface which is selected is displayed by an LED function indicator. The user can switch between the interfaces using the „Select“ button.

The unit is supplied complete with data logging software providing easy and rapid transfer of data to the PC. As an option, the data can be saved as an Excel sheet or a .txt file. Measurement data can quickly be printed out, using a specified1) USB or alternatively a printer with a serial plug-in connected to the IRiM. Applicable for the following operating systems: Windows XP, Windows Vista and Windows 7.

1) USB printer: HP Deskjet 6940

2) each ASCII printer

Delivery Content

The IRiM is delivered ready for use, with the following accessories :

USB cable, 4 batteries, screwdriver, CD-ROM, operating instructions and guarantee certificate

Order code: 21 40 50
