0555 6744 Dew Point Transmitter (with display; 1/2 NPT) 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)

Measuring Range: -30 to +50°C t_pd, 0 to +100 %RH

0560 5127 512 Digital Manometer/Anemometer +/- 10" WC (0 to 20hPa) by Testo

testo 512 simultaneously shows pressure and flow velocity (apart from version 0 to 2000 hPa) in the large, easily legible, illuminated display, the measurement values can be printed out on site with date and time as well as minimum and maximum values.

testo 512 has two switchable units for flow velocity, and for pressure, eight units can even be set.

In the testo 512, damping for a sliding mean value calculation can be individually programmed, tightness compensation is integrated. The actual value displayed can be frozen in the display with the Hold-button, and the minimum and maximum values can be displayed and stored in the instrument.

The TopSafe protects the instrument from impact, dirt and splash water in tough practical applications (optional).

The differential pressure measuring instrument testo 512 is available in four different versions:

• Measuring range 0 to 2 hPa
• Measuring range 0 to 20 hPa
• Measuring range 0 to 200 hPa
• Measuring range 0 to 2000 hPa (without flow velocity and Pascal measurement)

• 8 pressure units can be selected: kPa, hPa, Pa, mm H2O, mmHg, psi, inch H2O, inch Hg
• 2 flow velocity units can be selected: m/s, fpm
• Integrated tightness compensation
• Display illumination
• Max./min. as well as Hold-function
• Printout of measurement values incl. date/time and min./max. values

0555 6443 Compressed Air Flow Transmitter (1 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
