| Software description: Comfortable software
to edit the userdefined sensor curve of the GMH 3750 (e.g. for
calibration laboratories...) By means of this software probes can be
adjusted to the instrument. As result an overall accuracy of <0,03°C can
be achieved depending of the measuring range. Similar resistance curves
(e.g. Ni100) can be loaded to. The sensor curve can be stored external
and reloaded to the device. Receivable upon request!
calibrated systems:
General:
Te overall error of a measuring consists of the sum of the instrument
error and the probe error. To minimise the overall error, we offer
calibrated and optimised systems below. Due to their excellent system
accuracy they are especially suitable for quality assurance according to
ISO9000ff, as reference instruments in manufacturing processes, laboratory,
service and maintenance, etc.
The system optimisation is done via a special characteristic curve which
is determined for each temperature probe separately and stored in the
instrument.
