Over 120 pre-programmed methods — the A to Z of water analysis

The MD 610 is pre-programmed with over 120 water testing parameters and ranges covering the full spectrum of water quality analysis — from alkalinity to zinc. A single instrument replaces an entire library of dedicated analysers, making it the ideal solution for laboratories, field teams and process control.
PTSA and Fluorescein - Built for boiler and cooling water technicians
The MD640 adds PTSA and Fluorescein testing to the MD610's full method list, making it the complete solution for boiler and cooling tower water analysis alongside every parameter listed below.

Bluetooth® and AquaLX® app for field data management

The Bluetooth® interface allows testing data to be transferred directly from the field to smartphone or tablet via the free AquaLX® app. The app maps results as illustrative graphics with min/max limits and exports data as Excel®-compatible CSV files. Data can also be transferred to a Windows PC via the optional Bluetooth® dongle and software (PN 2444480).

Always up to date — free firmware updates

As new testing methods become available, firmware updates are available as a free download. Never have an outdated instrument again.

On-screen test guidance

With the push of a button, the MD 610 displays the correct reagent and sample cell required for each test, along with applicable conversion factors so results are shown in the required reporting units — no method manuals needed in the field.

Choice of reagent platforms

With over 120 pre-programmed methods, many parameters offer the choice of Tablet, Powder Pack or Liquid reagents — giving laboratories the flexibility to use the reagent format that best suits their workflow.

User-defined calibration curves

Create and store up to 35 user-defined methods on the MD 610 — ideal for proprietary testing methods or specific governmental and organisational standards. Supports up to a 25th order polynomial with full control over wavelength, range, units and decimal places.

One-Time-Zero function

Zero the instrument once for a new sample and all subsequent tests of that sample do not require re-zeroing — saving significant time during multi-parameter field or laboratory testing sessions.
