0554 9770 Probe Tube Flexible, 330 mm by Testo

In measurements on heating system burners, obstructed measurement areas can occur (e.g. due to sloping roofs, cramped basement rooms). In these cases, the usual straight flue gas probes can only be inserted into the flue with great difficulty. With flexible flue gas probes made of metal, there is a danger that the probe shaft is over-bent, and can break.

Our flexible probe shaft offers the ideal solution to this problem: It is made of very flexible plastic, and can thus be bent easily without breaking. This allows you to carry out flue gas measurements without any problems, at any measurement site.

• For flue gas measurements on heating system burners
• Extremely flexible plastic probe shaft
• Used for measurements at difficult-to-access measurement sites
• Attachable to modular flue gas probes

Our flexible probe shaft helps you to carry out flue gas measurements on difficult-to-access measurement area. Since the probe shaft is made of very flexible plastic, you can easily bend it, allowing it to be inserted into exhaust flues which are obstructed (e.g. by sloping ceilings)

Delivery Scope

Flexible probe shaft for attachment to modular flue gas probes.

0555 6441 Compressed Air Flow Transmitter (1/2" line) by Testo

The compressed air counters testo 6441 to testo 6444 are designed for the measurement, monitoring and recording of compressed air consumption, and therefore also for the determination of leakages in compressed air systems, consumption-based allocation of costs and the implementation of peak load management. Using the compressed air counters testo 6441 to testo 6444, transparency of consumption is created for compressed air, similarly as for the media current, water or gas, thus increasing the motivation of those responsible for the process regarding cost reduction measures and energy savings. The compressed air counters testo 6441 to testo 6444 record norm volume flow according to the calorimetric principle, which means the measurement procedure is independent of the process pressure and does not cause a permanent pressure drop. While the thermal, glass-coated ceramic sensor offers a high level of robustness and fast response times, the integrated inflow and outflow pipes ensure optimum accuracy.

• Measurement of norm volume flow in the measuring range 0.25 to 700 m³/h (DN15 to DN50 or 1/2"-2"); consumption quantity in m³; media temperature in °C
• Highest flexibility thanks to different signal outputs: Analog output 4 to 20 mA (4-wire), Pulse output, 2 switch outputs (parameterizable: consumption or volume flow-dependent, opener, closer, hysteresis, window)
• Built-in totalizer, even without additional analysis unit
• Operating menu with LED display
