1. Overview, Measuring Method and Models

1.1 How to use this manual

Thank you very much for purchasing the Paint-

Checker Mobile. The device is based on the outstand-

ing technology and high standards of OptiSense and

offers maximum precision mobile coating thickness

measurement.

This manual has been specially designed to guide

you step by step through the features and options of

your PaintChecker Mobile.

Please read the following section first!

• Before using your PaintChecker Mobile, read the

entire manual and all safety instructions to ensure

safe and proper operation

• The instructions in this manual refer to your

device at default settings

• The pictures and images used in this manual may

differ from the actual product

1.2 Challenges for today's coating companies

The challenges on coating companies are growing:

More individual products, smaller batch sizes and

more frequent colour changes. Added to this are the

growing documentation requirements and more and

more orders where the coating thickness is function-

ally relevant.

The PaintChecker mobile helps you to meet all these

requirements by checking coating thickness at an

early stage in the process – even before baking –

without contacting the part.

The mobile handheld device is particularly suitable

for random sample measurement as well as for coat-

ing inspection of large components or small batches.

1.3 The PaintChecker Mobile - Quick Reference

The OptiSense PaintChecker Mobile models support

accurate measurement of wet, powdery and solid

coatings on various substrates without contacting

the surface. The compact, lightweight, handheld

devices are designed for continuous, fatigue-free use

in the laboratory and on the production line.

The PaintChecker systems use the photothermal

measuring process to determine the thickness of

coatings on a wide variety of substrates.

As with other non-destructive coating thickness

measurement methods, e.g. ultrasonic, eddy current

or induction, photothermal coating thickness is not

measured directly, but calculated from measurement

signals. It is therefore important to consider the indi-

vidual thermal properties of coating material and

substrate.

The measurement is carried out without contact from

a distance of several centimetres. This means that wet

and sticky coatings can be measured just as easily as

soft and sensitive surfaces. A contamination of the

part or the carry-over of coating material is thereby

excluded in principle.

mentioned in this user manual are the property of

their respective owners. The use of brand names and

trademarks is for descriptive purposes only.

1.5 The photothermal coating thickness

measurement

1.5.1 Key technology for coating thickness checking

The photothermal coating thickness measurement is

a contactless measurement method for paints,

powder coatings and glazes on metallic and non-

metallic substrates. The different thermal properties

of coating and substrate are used to determine the

coating thickness.

The surface of the coating is warmed up by a few de-

grees with a short, intense light pulse and then cools

down again by dissipating the heat into deeper areas.

The thinner the coating, the faster the temperature

drops. The temperature curve over time is recorded

with a highly sensitive infrared sensor and converted

into coating thickness.

Fig. 1: The photothermal measuring method 1

1.5.2 Reproducible measurement results even with

most demanding coatings

Thick, heavy coatings need more energy to heat up

and cool down more slowly than thin, light coatings.

During the measuring process, it is therefore import-

ant, as in photography, that the strength of the light

source and the measuring time are optimally adjus-

ted to the respective situation, in order to obtain ac-

curate and reproducible measurement results.

In the case of powder coatings and paintwork, there

is also the fact that the user often does not want to

know the thickness of the powder or wet film that has

just been applied, but the later, final thickness after

baking or drying. For this purpose, the PaintChecker

Mobile takes the expected shrinkage of the coating

material during curing into account.

Thanks to the precise measuring spot, the method is

also suitable for the smallest components. The coat-

ing thickness can even be determined on bending

edges, corners and curved surfaces, where conven-

tional measurement technology reaches its limits.

Disturbances caused by rough surfaces or material

grains are compensated for by optical averaging, so

that even pastes and powders can be checked before

baking.

1.6 The model range

OptiSense is the world's leading provider of photo-

thermal measuring systems for coating thicknesses

on a wide variety of substrates.

A common feature of all mobile handheld devices is

their ability to measure a still soft powder layer on

substrates such as metal, wood, glass or plastic, re-

gardless of colour and type. With a simple measure-

ment the very cost-intensive rework of under- or

overcoating can be avoided.

The sensor head is detached from the control unit

and connected with a flexible cable. The lightweight,

ergonomically designed sensor can be carried com-

fortably in a holster and guided precisely and effort-

lessly to the component without touching or dam-

aging the sensitive coating.

LED sensors feature a larger measuring spot making

them ideal for freehand measurements on rough sur-

faces.

1.6.1 PaintChecker Mobile Gun-B

Fig. 3: PaintChecker Mobile Gun-B

The mobile OptiSense Gun-B is designed for contact-

less testing of freshly applied powder coatings prior

to burn-in.

1.6.2 PaintChecker Mobile Gun-R

The Gun-R model is particularly suitable for compon-

ents made of plastic or rubber.

Fig. 4: PaintChecker Mobile Gun-R

1.6.3 PaintChecker Mobile Laser Pen

Fig. 5: PaintChecker Mobile Laser Pen

The OptiSense mobile laser models are mainly used

for smooth coatings on metallic substrates. With their

tiny measuring spot the slim laser sensors are partic-

ularly suitable for coating thickness testing on delic-

ate small parts, corners and edges. A special version

with an extra short working distance allows you to

measure in very confined spaces or on coatings con-

taining high amounts of metal.

All OptiSense mobile models are eye-safe thanks to

the patented LARES® technology.

2.7 Dangers due to invisible light radiation from

the sensor

The PaintChecker Gun-B emits UV radiation!

The description of the dangers of the radiation used

here depends on the equipment. The risk class ap-

plicable to the PaintChecker is indicated on the warn-

ing label of the controller. The limits for radiation

duration given here have been determined in part by

an expert in laser technology and are not generally

applicable to devices of this safety class.

Coherent radiation of laser class 1

Radiation in the IR-B spectrum. Radiation of this class

can be dangerous if an optical instrument (magnify-

ing glass, microscope, etc.) is in front of the eye.

Glasses do not constitute an optical instrument in this

case.

ATTENTION! The accident prevention regulations of

DGUV regulation 11 as well as the reg-

ulations of the occupational health

and safety ordinance on artificial op-

tical radiation (OStrV) must be ob-

served

Irradiation of the skin near the exit aperture on the

measuring head can cause burns in the focus. The

laser radiation itself is not visible

Incoherent IR radiation of risk group 3 (RG3)

Radiation in the IR-A range: There is a low risk here.

Damage to the retina can be largely ruled out. Even

when looking into the light source for a longer period

of time, no damage occurs. Irradiation of the skin in

the vicinity of the exit aperture on the measuring

head can cause damage to the skin in the focus. The

laser radiation itself is not visible.

Radiation in the UV-B range poses a risk with short

exposure within the safety distance. Protective meas-

ures are essential here. When an individual threshold

dose (minimum erythema dose) is exceeded, the so-

called sunburn (UV erythema) occurs. The maximum

permissible irradiation of the skin is 64 seconds per

day.

If the cornea is irradiated for more than 120 seconds

within 1,000 seconds with the PaintChecker Gun-B,

an impairment according to the criteria of the EN

62471:2008 standard is to be expected.

radiation is accessible in this system, but

so weak that any damage can be

excluded. This is important because the

light radiation is in the non-visible

wavelength range
