About our Company
A company’s success depends on many factors.
Yet everything depends on one factor alone:
Quality.
Those who deliver quality, control the process chain –
knowing that it is only as strong as its weakest link.
As leak test specialists, we are not only close to our
clients’ requirements, but intentionally even closer,
because we take upstream and downstream process
phases carefully into consideration.
We have practiced this philosophy since our founding,
because we have always set ourselves high goals:
we had to meet the requirements of the automotive,
aircraft, and aerospace industries. Today we also serve
clients in food processing and medical technology.

H. SCHREINER’s measuring technology and systems
are used worldwide.
Our tests themselves have undergone exacting examinations and have been adapted to specific tasks performed
in production sequences. Our solutions are completely
integrated, using superior hardware.
The system architecture of software and the operating
concept guarantee perfect preparation of the acquired
data and smooth information exchange.
A high percentage of employees work in our Service
Department. We respond quickly. Stoppage time for
maintenance can thus be reduced considerably, and the
systems can be adapted more quickly to new requirements. This increases economic efficiency.

Perfect ergonomics and open for all systems,
as evidenced by the results.
We are a full-line
provider for leak testing. From mobile test
units via test computers with pneumatic
control through to
complex systems integrated in series production.
Measuring and testing means permanent interaction between man and machine, between test-results and PC.
It always is important to acquire information and to analyze
it in a targeted manner, thereby achieving a complete documentation of processes and reproducible results.
Precision, reliability, and fast cycle frequency of tests are
the result of our expertise in mechanical engineering, software engineering, and project management.
We attach paramount importance to an exemplary user
interface and system ergonomics. Therefore, our use of
high-resolution TFT monitors is not a luxury: Only the best is
good enough for careful control.
Our operator concept
is able to visualize
over 1000 parameters
at a glance. The basic
functions are clearly
organized; special
functions can be
integrated at any time.
Results must be interpretation-safe!
For this purpose we provide graphic analysis tools that
prepare print sequences, result lists, statistics, and
distributions.
Management via PC software is a matter of course.
The complete menu structure can be taken over from the
PC. And if one of our systems is part of the production
process it also speaks the client’s language.

Stoppage is a catastrophe
or a part of the real net output.
Quality Standards
Quality manifests itself not only in that our method is
reliable, but also when operating stoppages contribute to
economic efficiency. If a system is stopped for no other
reason than maintenance, this is proof of our claim to long
service life.
Highest level in production quality and the
use of resources. We
perform tests before
you test, and at the
same time we implement the exacting
requirements of two
QA standards: ISO
9001 and VDA 6.4.
The first standard is
relevant to the process
phases from development to delivery, and
the second sets the
yardstick even higher
within these phases –
in accordance with the
exacting standards of
the automotive industry. And in doing so we
abide by the principles
of saving energy and
protecting resources
according to the rules
of ISO 14001.
It is equally important that maintenance times are kept to a
minimum.
Our modular design is proven:
Sub-systems can be replaced easily – and we perform
recalibrations with inhouse developed tools and accessories.
As a company that is self-reliant in terms of crucial components, we guarantee the greatest possible independence
from suppliers and maximum flexibility within changing
product cycles.
Consequently, we are able to offer operating safety that
counts, particularly in demanding applications such as
cleanroom inspections or with gaseous test media.
Clients who want to supplement this kind of safety by
means of optimum prevention are able to monitor their
system with our LCP 820 from their PC via an internal
network or even via an external telephone line.

How soon is a system economically efficient ?
If possible, immediately.
H. SCHREINER systems
are designed
consistently in a
modular concept. This
increases flexibility for
adjusting to other
testing tasks and
brings considerable
reductions in tooling
times.
Our comprehensive
know-how about
production processes
guarantees smooth
integration of our
systems in upstream
and downstream
production phases.
Prices / Performance
When acquiring a system, the cost price certainly is one
of the most obvious features of economic efficiency.
Especially the ”invisible“ factors determine the cost of
ownership. It takes months and even years before they
become apparent. These factors speak for themselves !
The acquisition price of our products stands the test
of cost comparison.
Especially when comparing prices and performance! The
quality and safety features guarantee economic efficiency
with maximum runtimes, including efficient output. The only
thing that we reduced decisively are the amortization times.
Many of our clients, however, have not yet depreciated their
systems, even though this may be reflected in their tax
depreciations.
The openness for new requirements is maintained throughout the entire runtime. Users merely define additional
functions, and we integrate them according to default.
This type of flexibility makes the difference between
purchase and investment.

design, development, and implementation, right through to
on-site application training. We supply complete software
with local data acquisition and global data management and
data analysis.

In test engineering this saying makes sense, especially
because it was quoted the other way around.
Our clients are only able to develop trust if control has
already proven its function.
H.SCHREINER systems only perform tests where it
really matters:
Chemistry and Food Tech
Medical Technology
They test the engine, the radiator, the transmission. Our
automotive clients are not the only ones that benefit from
this competence.
Our 700 clients worldwide include companies in the chemical as well as in the medical and food technology sector.
