shall also extend to any liability in relation 
to tradability and / or suitability for a par-
ticular purpose under any implied liability 
which nevertheless exists under the law; the 
after-sales services shall be limited to the du-
ration of this warranty.
1.10 Limitation of liability
Your rights are limited to the repair or re
-
placement of this device as shipped. Pyrexx 
Technologies GmbH shall accept no liability 
for any special, incidental or consequential 
damages, including, but not limited to, re-
sulting loss of revenue, loss of prots, re-
strictions of the use of software /hardware, 
loss or recovery of data, cost of substitute 
equipment, downtime, damage to property 
and claims by third parties as a result of con-
tractual, statutory or tort recovery claims 
arising out of warranty, regardless of any oth-
er warranty, limited or implied by the law, or 
in the event that the limited warranty shall 
not apply, the liability of Pyrexx Technologies 
GmbH shall be limited to the purchase price 
of the device.
 f Check if at least one of the afore-
mentioned warranty exclusion 
reasons is present before making a 
warranty claim.
 f Keep in mind also that there are 
sufcient technical capabilities to 
determine, when submitting a 
warranty claim, whether the device 
has really been used as intended, 
and therefore if the warranty claim is 
justied or unjustied.
Pyrexx Technologies GmbH expressly re-
serves the right to charge a person who 
makes a warranty claim although at least one 
of the aforementioned warranty exclusion 
reasons is present with the costs associated 
with the necessary technical examination 
of the facts!
1.9 Disclaimer
Except for the limited warranty described 
herein, Pyrexx Technologies GmbH assumes 
no additional explicit or implicit liability un-
der the applicable statutory provisions. This 
excluded from a warranty exclusion!
In addition, build-up of fire residues  
(e.g. soot), as well as nicotine and grease 
deposits, which have caused a readily de-
tectable discolouration of the device, are 
categorized as contamination, which means 
the loss of any warranty claims. Especially 
nicotine and grease condensates do not only 
gather on the outer surface of the device, 
but also accumulate on the surfaces of the 
optical measuring components. Particularly 
there, the adhesion of condensates leads to 
premature deterioration of the optical prop-
erties of the measurement components, 
which the device can compensate through 
autonomous recalibration only within its 
physical limits.
Moisture damage / corrosion
If the device, and in particular its elec-
tronics, are damaged by moisture of any 
kind, any warranty claim shall be forfeited. 
Moisture thus is not only the exposure to 
uid, but also regular, above-average expo-
sure of the device to humidity (>  70%). 
Due to the effect of excessive humidity  
(e.g., steam / roasting fumes), the battery of 
the device is discharged above average, and 
the battery life is shortened considerably. 
Also, liquids and high humidity can damage 
the electronics of the device by causing 
corrosion.
Thermal damage
If the device has been exposed temporari-
ly or permanently to a temperature below  
0° C or above 70° C, any warranty claim 
shall be forfeited. In particular, no warranty 
shall be given for devices that were exposed 
to high temperatures and fumes in a re. 
Damage to the device as a result of frost 
/ cold, as well as heat damage, shall not be 
covered by the warranty.
Excessive load on the battery
Excessive load on the battery capacity 
through frequent triggering of alarm tones 
(more than once a month) may lead to pre-
mature consumption of the battery capacity 
due to the related battery consumption and 
to the loss of any warranty claims.
