Calibration
Before shipping all ERWEKA Hardness- and
Combination Testers as well as all electronic
temperature sensors are calibrated. The cali-
bration documentation comes with the unit.
For re-calibration ERWEKA units come with a
calibration menu in the standard firm-ware. On
some of the equipment the calibration menu is
password protected to assure that only qualified
staff can re-calibrate the unit.
For perfect operation and assurance of accu-
rate results, ERWEKA offers Calibration Ser-
vices on site by trained ERWEKA Service Man-
agement staff. All calibration tools used by
ERWEKA are constantly checked. Certificates
can be shown before the calibration procedure
takes place.
For Tablet-Hardness Testers ERWEKA now
offers a dynamic Calibration Tool which allows
calibration of the electronic load cell without
weights! The so-called AutoCal System uses a
certified external load cell and (optionally) cali-
bration software for easy and more accurate
calibration within max. 5 minutes. In addition
the unit will be calibrated at up to 50 points
within the measuring range for assurance of
results throughout the testing range. Results of
calibration can be printed out and/or stored by
the computer.
The system can be bought for self-calibration or
be used when having a calibration con-tract.
Re-calibration contracts are available either
monthly, every 3 months, every 6 months or
once a year.
Maintenance
To ensure a long lifetime for your units
ERWEKA recommends regular maintenance.
Dissolution Testers of the new generation are
equipped with a Service Interval Display, which
reminds the user every 3.000 hours of opera-
tion (stirring action), that maintenance is rec-
ommended.
Maintenance contracts are available. Our well-
trained service engineers perform the mainte-
nance.
Leasing
Not to invest capital ERWEKA offers leasing of
its equipment in co-operation with well-known
international banks.
Leasing is normally possible from a purchasing
amount of approx. € 10.000,00.
Used Equipment
ERWEKA also buys and sells used equipment.
When purchasing new ERWEKA equipment
ask, maybe we are interested to take back your
previous unit.
These units will be completely refurbished, not
just painted!
So when you need good equipment but your
budget is limited, ask for used equipment.
