Frequently asked questions
What is the delivery time for PESOLA catalogue items?
There is usually no delay. More than 99% of our catalogue items are
on stock. Should an item for once not be available on short term
basis, our homepage will display a shopping basket with a red arrow.
Can PESOLA spring scales be sterilised?
Yes. Permitted procedures of sterilizing PESOLA spring scales:
- In autoclave at 120°C at 1 bar for 45 min.
- 15 h in acetylene.
High temperatures along with high pressure set limits to fast sterilisation processes.
We particularly recommend sterilisation in acetylene as this process avoids humidity inside the scale.
Synthetic parts are incompatible with high concentrations of chlorine and its compounds.
Are the springs subject to fatigue due to age or frequent use?
No. They are designed to be fatigue resistant, even being used
a million of times.
Why are the springs of scales above 2kg / 20N not made of stainless steel like the ones with lower capacities?
They are made of quality steel spring wire with protection against corrosion to guarantee a perfect recovery of the zero position after discharge. Stainless steel wires would resist corrosion even better but do not meet our high requirements of measuring precision.
Certificates / Certification
Are there international certificates for PESOLA Spring Scales?
a principle we do not attempt to achieve certificates of compliancy
issued by standard organizations either from the EU, US, Canada,
Asia or others. We distribute our quality and precision spring scales
worldwide and would not be able to offer them at such good conditions
if we had to go through extensive administrative processes establishing
certificates in different regions of the world.
We have considered
in detail the rules e.g. for "CE" certification and found that due
to the fact that spring scales already have been in existence for
over 100 years, regulations have not kept up with technological development.
The rules for "CE" certification are based on the notoriously imprecise
spring scales of the past and request very low resolution. We would
therefore – in order to be CE compliant – have to reduce
the high resolution of our scales and downgrade the high precision
As a small company we will not be successful in influencing the standard
organisations to amend their rules towards modern spring scale technology.
As inventor and developer of the most progressive spring scale technology
worldwide, we are convinced to offer well-engineered spring scales
of highest quality and precision due to our experience of decades.
Is PESOLA Inc. quality certified?
Our internal procedures are organised
and controlled according to quality specifications. Our inspection
equipment is periodically calibrated by a gauging office. However
we refrain from establishing further measures of certification for
our company and prefer to invest into perfectly automated processes.
Every customer is free to verify our high quality standards. Furthermore
we optionally offer test certificates for our spring scales (please
see www.pesola.com -> quality).
A rate of return lower than 1 out of 1000 stands for the exceptional
PESOLA quality. Beyond warranty these few cases are being handled
in the most customer-friendly way and usually occur due to improper
You may therefore rely on the legendary PESOLA quality
