Introducing Air Capture Hood Testo 420 with Least Weight and Increased Precision

Pune, India, October 28, 2015 --( Testo offers a new air capture hood for larger air intakes and outlets, with the lowest weight in the market, and a unique level of precision. The testo 420 redefines previous standards, and stands out thanks to its easy handling and increased efficiency with an App integration. With it, the company is extending the range of VAC measuring instrument products, establishing itself in volume flow measurement as an innovative world market leader of the field of portable measurement technology.

Light, precise and convenient – the new air capture hood testo 420 is the leading solution for regulating volume flow at larger air intakes and outputs. With a weight of less than 2.9 kg, the testo 420 is the lightest air capture hood in the market. With regard to measurement precision too, the testo 420 sets new standards. Especially at swirl outlets, the flow straightener from Testo significantly reduces the usual measurement errors.

When regulating volume flows at larger air intakes and outlets in ventilation and air conditioning systems with the air capture hood testo 420, users can fulfil hygiene guidelines and Indoor Air Quality stipulations effortlessly and more efficiently than ever before – for example in industry, office rooms or in clean rooms.

In addition to its uniquely low weight, the ergonomic handles ensure especially easy handling. Funnel-shaped tension rod sockets support easy and quick set-up of the testo 420. Once compactly collapsed, the air capture hood can be easily and safely transported in the trolley included in delivery.

For more comfortable readout of the measurement values, the measuring instrument can be tilted and removed. Mobile devices such as Smartphones and tablets can furthermore be used as a second display and remote control via Bluetooth App integration. This makes using a tripod for high ceilings, for example, especially safe and comfortable. In addition to this, users can finalize the measurement report, and send it by e-mail, on site with the App – saving considerable time and increasing efficiency.

The testo 420 should especially be useful for monitoring indoor air climate in offices, malls or in production companies - be it food, pharma or others. These must accomplish two tasks. On the one hand, it should guarantee uniform ambient conditions for a faultless production process, and highest product quality while on the other, it may not endanger the health of the staff.

This is why the VAC systems in such rooms are required to adhere to stringent norms and guidelines. The crucial factor is the prescribed air exchange rate. Depending on the VAC system, this rate must be checked several times a year by an air conditioning technician, by measuring the total volume flow at the air outlet or in a duct. In measurements at air outlets, a problem occurs: Rooms such as these have large swirl outlets installed as standard, which do not blow the air into the room straight, but instead continually swirl it. The consequence of this swirl: Air flows are often incorrectly measured at these locations. And this complicates the determination of the volume flow substantially.

The air capture hood testo 420 significantly reduces measurement errors at larger swirl outlets. The innovative flow straightener converts the turbulence into an almost uniform air flow, leading to a considerably more accurate measurement.

In addition to this, the hood records the ambient climate using an integrated temperature and humidity sensor as well as an absolute pressure sensor. Another advantage of the hood is its low weight of only 2.9 kg. In combination with ergonomic handles, frequent or difficult measurements can therefore be conducted comfortably and safely.

The application is simple too: Funnel-shaped tension rod sockets support easy and quick set-up, and the trolley included in delivery ensures safe transport. Mobile devices such as smartphones and tablets can be used as a second display and remote control via Bluetooth App integration – especially useful for the safe use of a tripod for high ceilings.

After the measurement, the App allows the finalization and sending of the measurement protocol directly on site. Differential pressure and Pitot tube measurements are also possible with the removable measuring instrument, by simply entering the duct geometry.

With the air capture hood testo 420, users can quickly and accurately fulfil the legal regulations on Indoor Air Quality for ventilation and air conditioning systems in industry.
