The dynaROCK II works according to the Leeb rebound hardness test me­thod for metallic materials. It is
developed and produced by BAQ GmbH.

The dynaROCK II combines easy operation with high precision and reliability. For different applications,
six impact device types are available. The type of the connected impact device is identified automatically.

•   Fast and easy hardness testing

•   Measuring method according to DIN 50156 and ASTM A956

•   Robust metal casing

•   Large colour display

•   Embedded Li-ion battery

•   12 groups of materials

•   Extensive storage and statistical functions

•   USB interface and PC software

•   Made in GERMANY

IMPACT DEVICES

Type D:   Impact device for most hardness testing tasks

Type DC: Extremely short impact device -access  or pipes

Type C:   Reduced impact energy e.g. hardened parts

Type D+15: For small placement surface

Type DL: Impact device with longer impact body

Type G:   Impact device with increased impact energy
for measurements on heavy casting and forged parts.
The surface quality requirements are lower than type D.
The Measurement range up to Brinell 650 HB

Anti-corrosion coatings on the interior of storage tanks are critical when storing many types of products, whether salt
or freshwater, gasoline, ballast, foamy liquids, or diesel. Typically, regulations are in place to ensure that the right
coating is used. Quality inspection of the coating is an essential part of compliance with the regulations.

Although there are many such regulations, the Petrobras standard, N-1201:2008 – “Anticorrosion Coatings for the
Interior of Storage Tanks”, is a good example.  This multinational company Petrobras, uses the above-mentioned
standard wherever it has operations. This standard is in the public domain and can be accessed online from their
database; it regulates all painting processes applied to storage tanks, from surface preparation, to painting and
coating, through to final compliance inspection.

The Petrobras standard N-1201:2008 prescribes the
following coating types and coating thicknesses for
the different products to be stored, as listed in Table 1:

4.2.1 Coating Type 1
4.2.1.1 Primer: one coat epoxy-zinc phosphate: 100 µm
4.2.1.2 Top coating: two layers of non-solvent epoxy
paint: 150 µm minimum thickness per layer.
4.2.2   Coating Type 2: one layer of zinc-ethyl-silicate
paint: 75 µm

4.2.3  Coating Type 3: one layer of non-solvent epoxy
resin, cured with polyamine and embedded with
ceramic or fiberglass: 800 µm

Once they are applied, the coatings need to be inspected – a tricky
job, being insitu! The tank still has noxious paint fumes. The
technician wearing protective gear and headlamp (perhaps the only
source of light) is lowered into the vessel to measure the coating
thickness at a number of positions.

Since a handheld gauge with integrated probe will not work, as most
tank geometry does not permit access it in some spots, an external probe
is necessary.

FISCHER developed the MP0R-FP products for just such applications performed under difficult conditions. While
other thickness gauges on the market require the use of both hands (one to hold the instrument and the other for
the probe), the wristband optional accessory is indispensable when the task itself requires some juggling.

MP0R-FP series calibration can be also be done outside the tank using FISCHER calibration accessories and a
piece of the original tank material, avoiding calibration directly inside the tank.

The unmatched accuracy and repeatability performance of the MP0R-FP series from FISCHER make the ideal choice
for checking compliance with regulations.
