Testo 0635 0551 | Lux probe (digital) - for measuring illuminance, wired Product Description Use the lux probe with the compatible testo multifunction measuring instrument (please order separately) to determine illuminance.   Lux probe – features The lux probe is ideal for determining the illuminance in workplaces. It assesses the illuminance according to the V-lambda curve, which corresponds to the sensitivity of the human eye in daylight. White or warm light LEDs (K< 5,000) can also be measured without any problem. The 1.4 m cable length means that you can place the probe directly at the measuring location and carry out the measurement from a sufficient distance. So the readings are not affected by your shadow. The clearly structured measurement menu for long-term measurement enables the measuring instrument to be operated intuitively. Reading trends are reliably recorded thanks to the convenient input of measurement time and measuring cycle.   Intelligent calibration concept You will get exceptionally accurate measurement results with the digital probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe in for calibration – so the measuring instrument remains in continuous use.   Areas of application for the lux probe Light conditions play an important role, particularly in the ergonomic assessment of workplaces. In order for light to also be good light, the illuminance must meet certain minimum values. Use the lux probe to check the illuminance in offices and production areas, hospitals, museums or schools with reliability.   Delivery Scope Lux probe with fixed cable (cable length 1.4 m) and calibration protocol.

Testo | High-precision 100 mm vane probe head including temperature sensor Order-Nr.  0635 9370   Intuitive: parallel determination of air velocity, volume flow and air temperature Precise: detects the smallest air velocities from as little as +0.1 m/s and is therefore ideal for laminar flow measurements in cleanrooms Convenient: probe head is easy to attach to the universal Bluetooth or cable handle or to the extendable telescope (all available to order separately) Intelligent calibration concept: only send in the probe head for calibration More applications, less equipment: if you already own one of our probes with a universal handle, you can easily expand your portfolio of probes with the high-precision 100 mm vane probe head.     Product Description Combine the probe head with the handle adapter for air velocity probes and simply plug onto the handle with cable or Bluetooth. For convenient measurements at ceiling outlets, we recommend the extendable telescope for air velocity probes including 90° angle. Note: Please note that you need the handle adapter (order number 0554 2160) to use this probe head in conjunction with the handles.     Delivery Scope High-precision 100 mm vane probe head including temperature sensor, bracket for testovent measurement funnel and calibration protocol.      Technical Data   Temperature - NTC Measuring range -20 to +70 °C Accuracy ±0.5 °C  Resolution 0.1 °C   Velocity / Volume flow Measuring range 0.1 to 15 m/s Accuracy ±(0.1 m/s + 1.5 % of mv) Resolution 0.01 m/s   General technical data Storage temperature -20 to +70 °C Weight 120 g Dimensions 180 x 105 x 46 mm Operating temperature -20 to +70 °C Probe head diameter 100 mm Product colour Black   Downloads  Product Brochures Data sheet testo 440  (application/pdf, 3.365 KB) Manuals Instruction manual testo Air velocity and IAQ probes with fixed cable  (application/pdf, 349 KB) read more

Testo 0632 1271 | CO probe (digital) - with Bluetooth Product Description Use the CO probe with the compatible testo multifunction measuring instrument (please order separately) to detect carbon monoxide.   CO probe with Bluetooth – features The readings of the CO probe are transmitted to your measuring instrument via Bluetooth, up to a distance of 20 m. Particularly useful: store individual readings directly in the measuring instrument by pressing the button on the probe. The clearly structured measurement menu for long-term measurement enables the measuring instrument to be operated intuitively. Reading trends are reliably recorded thanks to the convenient input of measurement time and measuring cycle. You can use these trends to evaluate changes in the CO concentration.   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. Or order the cable handle to connect testo probe heads. This is an advantage if Bluetooth signals are not permitted. if the CO sensor needs to be replaced in the distant future, you can change the probe head.   Intelligent calibration concept You will get exceptionally accurate measurement results with the digital CO probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe head in for calibration – so the measuring instrument remains in continuous use.     Areas of application for the CO probe Carbon monoxide (CO) is a poisonous gas which is colourless, odourless and tasteless. Its sources include the incomplete combustion of substances containing carbon (oil, gas and solid fuels, etc.). This is why it is necessary to regularly check CO emissions at the combustion points of heating systems and also in the areas around them.   Delivery Scope CO probe with Bluetooth (consisting of CO probe head and Bluetooth handle), 4 x AA batteries and calibration protocol.
