Reliable handheld water quality measurement

The MC-W05 is a 5-in-1 water quality testing pen designed for fast, accurate spot-checking of water quality parameters in the field or laboratory.

It measures:

• pH
• Electrical conductivity (EC)
• Total dissolved solids (TDS)
• Salinity
• Temperature

Its compact pen-style format makes it easy to carry, store and deploy wherever water quality needs to be verified.

Intended use – instrument only

The MC-W05 is supplied as a standalone testing pen, making it suitable as:

• A replacement meter
• A spare instrument

• An additional pen for multi-site or multi-user environments

For accurate measurements, calibration is required before use.

For a complete, ready-to-use solution including buffers, conductivity standards and labelled cups, see the MC-W05-SYS 5-in-1 Water Quality Testing System.

Correct probe care – included as standard

To protect the pH electrode and maintain long-term accuracy, the MC-W05 includes 30 mL of potassium chloride (KCl) storage solution.

pH probes must be kept moist when not in use.
Distilled or deionised water must not be used, as this can permanently damage the probe.

• Meascom MC-W05 5-in-1 water quality testing pen
• 30 mL KCl probe storage solution
• Protective probe cap
• User instructions

When to choose the MC-W05-SYS instead

If you need:

• Calibration buffers
• Conductivity standard (1413 µS/cm)
• Labelled measurement cups
• A complete professional setup

We recommend the MC-W05-SYS 5-in-1 Water Quality Testing System, which includes everything required for accurate calibration and testing out of the box.
