0699 6446/12 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: -50 to +350 °C

6621 HVAC Temperature & Humidity Transmitter by Testo

A broad variety of the testo 6621 transmitter is available. Depending on the application in a room or in a duct, the corresponding designs can be selected. A display and an external probe are available as options. You can choose between the housing colours grey and white. The testo 6621 is persuasive in technical terms thanks to the patented humidity sensors that guarantee the highest accuracy. The sensors and the analog outputs can be adjusted, analyzed and parameterized via the external interface using the P2A software.

0563 8450 845 Adjustable Focus IR Thermometer, 75:1 optics with aluminium case by Testo

For the first time, surface temperatures with smallest diameters can be measured accurately at short and long distances. The switchable optics for far-field and close focus measurement make this possible. Measurements in the far-field are made with an optical resolution of 75:1. Surface temperatures can thus be measured accurately even at greater distances from the object to be measured. At a distance of 1.2 metres from the object, the measurement point diameter is only 16 mm. A cross laser marks the measurement point exactly. For measurements at a small distance from the object to be measured, the close focus optics provide a measurement point diameter of only 1 mm at a distance of 70 mm! Two laser points mark the measurement point.

• Switchable optics for far-field measurements (75:1) and close focus (1 mm, 70 mm distance)
• Especially bright cross laser sighting for indicating the actual measuring point
• Reference accuracy ± 0.75 °C with super-fast measurement technololgy (scanning 100 ms)
• Backlit display (3-line) showing °C, min./max. values, alarm limit values and degree of emission; additional display with humidity module: %RH, °Ctd
• Optical and audible alarm when limit values are exceeded
• Probe socket for TC probes for determining emissivity

• PC software for archiving and documenting measurement data (included in delivery)
• Tripod fitting for online measurement via USB cable (included in delivery)
