0555 6743 Dew Point Transmitter (with display; G1/2) by Testo

The testo 6740 was especilally developed for trace humidity measurement in compressed or dry air (e. g. granulate dryers). Thanks to a special adjustment, optimum accuracy in the trace humidity range has been achieved. The result of the development of the testo 6740 is a measuring range of -45 °C_td to +30 °C_td and excellent accuracy.

For the display of the relevant trace humidity parameters, a freely scalable analog output is available, optionally with a switch contact plug for MAX monitoring. In addition to this, the testo 6740 stands out thanks to its compact and userfriendly design, such as the rotatability of the housing by 350° for the optimum positioning of the display.

• Measurement of dewpoints in the range from -45 °C_td to +30 °C
• Testo polymer humidity sensor with high accuracy and longterm stability
• Convenient operation via the display menu
• Analog output 4 to 20 mA (2-wire) and optional alarm plug with 2 integrated switch outputs
• Compact design with rotatable housing by 350° for optimum positioning of display
• Display with operating menu (optional)
• Trace humidity adjustment without reference measuring instrument possible on site with accessory (2-point adjustment device)

0699 6446/1 6446 Compressed Air Meter 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. 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.

The version testo 6447 offers everything the testo 6446 provides, in addition the removal of the probe under pressure is possible (patented screw fitting). The larger nominal values refer especially to important compressed air pipelines, often the main supply line after preparation.

• Measurement of norm volume flow in the measuring range 6.7 to 27500 m³/h (DN65 to DN350 or 21/2"-10")
• Exchangeable fitting: Probe removal under pressure possible (testo 6447 only)
• Material selectable between galvanized steel and stainless steel
• 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
• Cleanable sensor
