0699 6447/14 6447 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

6681 Temperature & Humidity Transmitter by Testo

Industrial humidity measurement demands absolute professionalism. Not only in running the system, but also in the measuring technology used. The industrial humidity transmitter testo 6681, combined with the probe series testo 661x fulfils these high demands. The testo 6681 has a number of additional features, above and beyond the properties and benefits of a conventional transmitter, which will delight practitioners. This and other reasons make the

testo 6681 the first choice in drying technology, trace humidity and compressed air process technology, as well as in demanding air conditioning technology, e.g. in cleanrooms.

• Optimum adjustment concept thanks to adjustment of the entire signal chain incl. analog adjustment
• Profibus, Ethernet, relay and analog outputs allow optimum integration into individual automation systems
• Self-monitoring and early warning guarantee high system availability
• Calculation and presentation of all relevant humidity parameters
• P2A software for parameterization, adjustment and analysis saves time and costs in commissioning and maintenance
• Display with multi-language display
• Robust, easy-to-clean metal housing

400563 5122 512-2 Digital Manometer/Anemometer Kit 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).

Kit Includes:

• 0560 5128 - 512 Digital Manometer +/- 80" WC (0 to 200hPa)
• 0635 2145 - "L"-type pitot tube 13" SS 1112°F max
• 0554 0440 - Silicone hose (16' long)
• 0516 0201 - Carry case

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

Measuring Range: -200 to +400 °C
