The First Emissions Analyser which Thinks Ahead!

Testo (UK) has developed a new portable emissions analyser which guides the user safely through professional gas analysis, thanks to useful instrument pre-settings. The Testo 350 is used, for example, in commissioning, maintenance and operative measurements on industrial burners, industrial engines, gas turbines or flue gas scrubber systems, as well as in the measurement of the gas atmosphere in a furnace room or in kilns. In addition to this, the Testo 350 supports in the control and monitoring of officially prescribed emission limit values in flue gas, and in function tests on stationary emission measuring instruments.

Depending on the requirement, the Testo 350 consists of a control unit, an analyser box and a gas sampling probe. Using the removable control unit or in direct connection to a PC or laptop (USB or Bluetooth® 2.0), the analyser box can be easily operated. The transfer of measurement data is therefore possible even when the exhaust gas flue and the adjustment site are separated. This is helpful, for example, when dealing with industrial burners. After easy configuration of the measurement procedure by the user, the analyser box carries out the measurements automatically and stores the measurement values.

The measurement values are clearly presented in the large, colour graphic display of the control unit (3.5“, 240 x 320). Users can freely configure various measurement objects such as burners, gas turbines or industrial engines. In the display, typical fuels as well as an expedient order of the flue gas parameters are presented for each of these measurement objects. In addition to this, calculations and instrument pre-settings are stored. Useful information in the display always guides the user safely through the measurement. This allows the flue gas analyser to be easily operated without previous knowledge of the instrument. The work steps leading up to the start of the measurement are reduced – Testo 350 is the first emissions analyser which thinks ahead!

Inherently closed cooling loops isolate the entire instrument electronics as well as the gas sensors from dirt from the surrounding air. This optimum protection ensures the analyser can be used even in tough surroundings. Downtimes due to instrument contamination are thus almost completely eliminated thanks to this intelligent design and robustness. The plug connections for the gas sampling probes and databus cable are locked using a bayonet fitting, and are thus securely attached to the analyser box. This hinders unintentional removal, avoiding measurement errors.

Thanks to the selection of the measurement objects in the display, as well as the carrying out of measurement procedures, faster routine work is possible in daily applications – supported also by the new colour graphic display. The service opening on the underside of the instrument allows fast access to all relevant serviceable and wearing parts such as pumps and filters. This means users can carry out cleaning, maintenance and replacement directly on site. This reduces service times and maintenance costs.
