0560 5281 526-2 Differential Pressure Meter (0 to 2000hPa/ 29psi, 0.05% acc.) by Testo

testo 526 is the differential pressure meter for industrial applications. Critical processes can be measured and monitored highly efficiently with an accuracy of up to 0.05% of the full-scale value.

• Temp. compensated differential pressure sensor 0 to 2000 hPa built into instrument
• Available in 2 accuracy classes: 0.1%/0.05% of full-scale value
• Measures leakage rate (drop in pressure per time)
• Checks drop in pressure in containers, cables etc. via the built-in test menu
• 2 probe sockets to connect additional probes for measuring pressure, temperature, current/voltage

Measuring Range: -200 to +1100 °C

0560 5128 512 Digital Manometer +/- 80" WC (0 to 200hPa) 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

0554 1749 DIN rail mount power supply, 90-240 V AC / 24 V DC (2.5 A) by Testo

• For the external power supply
• 90 - 264 VAC / 24 VDC (2.5 A)
• Easy top-hat rail mounting

0699 6446/5 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

Measuring Range: 0 to +500 ppm CO
