Features

Easily accessible service opening

 

testo 350 service opening   

The service opening in the underside of the instrument allows very easy access to all relevant service and wearing parts such as pumps and filters, which can then be quickly cleaned and/or exchanged on site.

The advantages:

  • Reduction of instrument unavailability due to service times
  • Cost savings due to instrument maintenance and/or exchange and cleaning of wearing parts by the user
  • Immediate access to all relevant wearing parts

Thermally separated sensor chamber

 

testo 350 sensor chamber   

The sensor chamber is thermally separated from the other instrument components. This reduces possible sensr drifts caused by thermal influences.

This allows the maximum reliability pf the measuring instrument to be achieved.

Easy exchange of the gas sensors

 

testo 350 gas sensors   

The gas sensors are pre-calibrated and can be exchanged, replaced or extended by further measurement parameters without test gas – if necessary directly on site.

The advantages:

  • No more long service times
  • Flexible extension of the testo 350 by further gas measurement parameters when applications or regulations change.
  • A report is immediately issued when the NO sensor filter is used up. Then only the filter needs to be changed, and no longer the whole NO sensor.

Automatically monitored condensate trap

 

testo 350 condensate trap    The automatic monitoring of filling level reports when the condensate trap needs to be emptied, and a few minutes after the report, the measurement gas pump is automatically stopped. This provides the highest protection of the analyzer box and the gas sensors from damage by condensate entry.

External cooling loop

 

testo 350 cooling loop   

Closed cooling loops isolate the instrument electronics and sensors from the ambient air. The interior of the instrument is cooled via a heat exchanger and therefore does not come into contact with dirty or aggressive ambient air.

The advantages:

  • Damage to the internal electronics are thus effectively prevented.
  • The instrument can also be safely used in dusty or dirty atmospheres.
