Testo manufacture a number of tools for the HVAC/R industry, from Flue gas analysers to Refrigeration manifolds. Perhaps our most sought after instruments however, are vane anemometers. Combining top build quality with competitive pricing, testo anemometers remain a must have tool for the UK ventilation & AC engineer.
The Domestic Ventilation Compliance Guide states that if you install, commission or inspect fixed ventilation systems in new or existing dwellings, you need to use an airflow measuring device, calibrated at a UKAS accredited calibration centre, to record the final air flow rates.
The aim of the regulation is to ensure adequate ventilation while minimising energy use, noise and discomfort (Enforcement of the regulation is tightening up so don’t take the risk!). For more info on the Part F building regulations please visit: www.testolimited.com/legislation
Our best selling anemometer. The compact testo 417 anemometer kit with built-in flow/temperature vane Ø 100 mm to measure flow speed, volume flow and temperature. Volume flow is shown directly in the display.
Accurate volume flow calculation thanks to easy input of duct area. In addition, it is easy to switch to the current temperature reading. The flow direction, i.e. drawn in or blowing, is visible in the display. Timed and multi-point mean calculation provide information on mean volume flow, flow speed and temperature readings.
The optional funnel set facilitates efficient measurements at ventilator grilles and disc outlets. Min/max values can also be shown in the display. Current readings can be frozen in the display using the Hold function. Plus if you buy a Testo 417 F-Reg Kit you’ll get the next year’s UKAS calibration with a 15% discount (Only Available Direct from Testo)- With integrated 100 mm vane and battery.
The Testo 417 F-Reg Kit is designed to make compliance simple for the installer; the Testo 417 measures and displays the volume flow at a touch of a button, without the need for complicated grill size calculations. Two funnel sizes are included in the set ensuring simple flow capture for both circular and square grills.
• Testo 417 anemometer with built-in 100mm vane
• 2 attachable funnels (200x200mm & 330x300mm)
• UKAS (ISO17025) calibration certificate
The Testo 417 now takes measurements in litres per second, and measures flow speed, volume flow and temperature. The flow direction and volume flow is clear and easy to read on the display. Timed and multi point mean calculation provide further functionality and the funnel set facilitates efficient measurements at large ventilation outlets. Testo have a fully equipped service, calibration and repair centre. We have a UKAS (ISO/IEC 17025:2005) accredited laboratory for several parameters including airflow in the range of 0.1 to 30 m/s.
If the 417 is a little to advanced for your needs then perhaps the testo 410 will be more suitable. It measures both air speed and temperature and is part of our pocket size range. It is ideal for quick spot checks at air outlets on account of its integrated measurement with the 40mm vane. Timed mean calculation is possible. In addition to air speed and temperature, testo 410-2 also measures air moisture. Testo’s patented humidity sensor guarantees accurate readings. In this way, air conditions can be reliably checked.
