Calibration

Laboratory

for Electrical Quantities DKD –K –19701
accredited per DIN EN ISO/IEC 17025

Accredited measured quantities: direct voltage, direct current
values, DC resistance, alternating voltage, alternating current values,
AC active power, AC apparent power, DC power, capacitance and
frequency

Competent Partner

GOSSEN METRAWATT GMBH is certified in accordance with
DIN EN ISO 9001:2000.
Our DKD calibration laboratory is accredited by the Phys-
ikalisch Technische Bundesanstalt

(German Federal Institute

of Physics and Metrology)

and the Deutscher Kalibrierdienst

(German Calibration Service)

in accordance with DIN EN ISO/

IEC 17025 by under registration number DKD–K–19701.
We offer a complete range of expertise in the field of metrol-
ogy: from

test reports

and

proprietary calibration certificates

right

on up to

DKD calibration certificates

.

Our spectrum of offerings is rounded out with free

test equip-

ment management

.

An on-site

DKD calibration station

is an integral part of our ser-

vice department. If errors are discovered during calibration,
our specialized personnel are capable of completing repairs
using original replacement parts.
As a full service calibration laboratory, we can calibrate instru-
ments from other manufacturers as well.

DKD Calibration Certificate Reprints

If you order a DKD calibration certificate reprint for your
instrument, please provide us with the reference numbers
indicated in the upper and lower most fields of the calibration
seal. We do not need the instrument’s serial number.

Warranty

The warranty period for all measuring and calibration instru-
ments of the METRA HIT series is 3 years from delivery.
A warranty period of 12 months is granted for calibration.
Warranty covers defective material and workmanship, not
including any damage caused by inappropriate use or oper-
ating errors as well as any follow-up costs.
