High Precision Cleanness Meter

Model THEZ-MS-002

A portable, self-calibrating cleanliness meter that reads surface gloss quickly and continuously. Built for stone, tile, car paint, plastics and polished metal.

< 1 sper measurement
10,000readings per full charge
0manual adjustments
THEZ-MS-002 held against a ceramic tile floor, display reading 74 CLEAN

Pocket-sized. Fast. Calibrated for you.

The THEZ-MS-002 turns surface gloss into a clear cleanliness reading, so cleaning results can be checked on the spot instead of judged by eye.

1

Compact and lightweight

About the size of a name card and easy to carry around, whether on a job site or a factory floor.

2

Fast, accurate reading

Each single measurement takes under one second and returns an accurately measured value.

3

Continuous mode

Long-press for 1 second to switch on continuous measurement and scan a surface as you move across it.

4

Self-calibration

The meter calibrates itself. No manual adjustment is needed before use.

5

High-endurance battery

Up to 10,000 continuous measurements after a single full charge.

6

Multi-surface capability

Reads glare from stone, tile, car paints, plastics and polished metal surfaces.

One scale: gloss units (GU)

The meter reports how strongly a surface reflects light. Dirt and residue scatter light, so a cleaner surface reads higher within its material class.

0 to 10 GU Matte

Reflects almost no light. The surface is rough or very fine-textured.

10 to 70 GU Semi-gloss

Reflects a moderate, medium sheen.

70+ GU High gloss

Clearly reflects light from a smooth, shiny surface.

Reference ranges by surface

Typical readings for each condition. Compare a measurement with the matching range to judge whether a surface is dirty, clean or glossy.
