DETAILS OF CERTIFICATE CHANGES (for issues 1 and above):
Issue 1 of the certificate
This issue of the certificate, introduces variation 1 of the Detector Unit and the Probe. The following
modifications are introduced by this variation:
To prolong the battery life, the probe power generation and protection circuit on the MAIN PCB in the Detector
Unit has been redesigned. The circuit contains voltage enhancement and controlled semiconductor voltage
shunts. These changes give increased output parameters to the probe.
PX50x Series Probe Assembly now uses a housing made from an alternative plastic material. The circuit has
been modified to provide increased power to the sensor to improve its sensitivity.
The name of the applicant and manufacturer, has been changed from Adixen Sensistor AB to Adixen
Scandinavia AB. The introduced modifications have been assessed and tested according to ExTR
GB/SIR/ExTR09.0206/01, which also include assessment and test of the HS85 sensor.
Issue 2 of the certificate
This variation - variation 2 - introduces the following modifications:
The LCD module has been modified and the bill of material drawings has been amended. New components on
the LCD module, have affected the original thermal assessment. The modifications have been assessed
according to ExTR GB/SIR/ExTR10.0252/00, which also introduces and confirm compliance with IEC 60079-
26:2006 (ed 2).
