Information on the calibration of newly purchased equipment and what it means to you.
Calibration and its certification comes in varying forms on new equipment and in this section, we will break it down into the three areas that we use to classify calibration state at the point of purchase.
Manufacturers Calibration Certificate
This is a calibration certificate offered by the manufacturer supplied with the tester. This is also known as an end-of-line certificate or manufacturer’s certificate. These certificates vary depending on the manufacturer and product. They will not have your company's name on them and don’t always show proven test results.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes complete with the manufacturer's calibration certificate. Please be aware that these certificates are generic and may also be time-lapsed.
If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.Manufacturers Certificate of Conformity
A manufacturer's certificate of conformity is not a calibration certificate. It is merely a statement that the equipment has been produced to operate within its intended application, it has no traceable certificate or constitutes any defined results for accuracy before leaving the manufacturing process.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.Personalised traceable calibration certificate from isswww
This is a calibration certificate created by us at ISS. This certificate is fully traceable to national and international standards. The certificate will show your company's details, tester information, proven test results and the equipment used to carry out the test. Nearly 90% of all calibrations we do are done in-house in one of our many fully equipped laboratories. You can add this service to your order on the product page before you checkout.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
We are on occasion able to offer FREE calibration on certain products at their point of sale (newly purchased equipment only) please look out for the following badge on the product's page to take advantage of this free offer.

Applications:
Convenience and maximum flexibility for duct and outlet measurements
With our large range of air velocity probes (please order separately), you can carry out simple and convenient measurements even at locations that are difficult to access in ventilation ducts or at air outlets:you will even find it easy to carry out measurements in particularly large ducts. This is because the extendable telescope on the hot wire and vane probe (Ø 16 mm) with universal handle can be further extended using the telescope extension – enabling you to attain a total length of 2 metres.
Carry out measurements at air/ceiling outlets effortlessly and without using a ladder. Fit your vane probe (Ø 100 mm) with the telescope with 90° angle and, if necessary, with the telescope extension (both can be ordered separately).
Greater freedom thanks to Bluetooth: the air velocity probes with Bluetooth have no inconvenient cable connection to the measuring instrument, and they transmit readings up to a distance of 20 m. Press the button on the probe to operate the measuring instrument – for example, to start and stop a series of measurements (timed mean calculation).
Attach the testo 440 air velocity and IAQ measuring instrument to metal surfaces (e.g. ducts) easily using the practical magnets.
Benefit from fast calculation of the volume flow: in the “volume flow” measurement menu of the multifunction measuring instrument, configure the dimensions and geometry of the duct cross-section – the measuring instrument shows you the volume flow straight away.
Details:
Measure in just a few clicks with the testo 440 multifunction measuring instrument
Carry out your measurements quickly and easily: the air velocity and IAQ measuring instrument automatically detects each connected probe. This means that there is no need for you to manually reset the parameters when changing probes. Clearly structured measurement menus for measuring the volume flow in ducts/at outlets, funnel measurement, measuring the degree of turbulence, determining the cooling/heating output, mould detection and long-term measurement provide you with optimum support during your day-to-day work.Wireless and space-saving: more applications, less equipment
Endlessly versatile: a universal handle can be connected to all probe heads – so you can master more applications using less equipment and save space.The Bluetooth handle makes it more convenient to carry out your measurement and guarantees less cable clutter in the case. It makes it possible to carry out measurements without any bothersome cable connection and it transfers readings up to a distance of 20 m. Or as a practical alternative, use the cable handle to connect testo probe heads. This is an advantage if Bluetooth signals are not permitted.
Practical measurement data management
The multifunction measuring instrument stores up to a max. 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on your computer (e.g. with Excel). With the testo BLUETOOTH/IRDA printer (please order separately), you have the option of producing a report printout of the measurement data directly on site.Intelligent calibration concept for maximum precision
You can rely on accurate measurement results when using our digital probes, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probes in for calibration. The multifunction measuring instrument can therefore remain in continuous use.Advantages of measuring with the testo 440 air velocity and IAQ measuring instrument
