Hello, thank you for your comment. If you are having trouble with your testo 270, please email info@testo.co.uk with your full enquiry so they can offer you the best advice. It may need to come back to us for calibration so if you can include all the necessary detail that would be much appreciated, thank you.

Hello, thank you for your comment. For the reference oil used for spot checks on the testo 270 calibration the following deadlines apply. either a) the best before date as printed on label, or b) Opening date plus 6 months. However if the 2 expiration dates differ then the earlier expiration date applies. If you need further information please email info@testo.co.uk thank you.

@@Testolimited it means if the oil used is expired we cannot use it or it gives us incorrect measurements

Hi @tamjidshafiq to see efficiency readings you will need to start a flue gas measurement and then use the down arrow to scroll through various measurements. Here you will find both net and gross efficiency readings. I hope this helps, if there's anything else we can help with please don't hesitate to contact us.

Hi, thank you for your comment. This is not a known issue currently, is it possible you have not given the app permission to access your camera? Any further questions please do not hesitate to get in touch on 01420 544433 or email us at info@testo.co.uk

Good morning Matteo, thank you for your question. You will need to carry out the zeroing process outside in fresh air. If this doesn't solve the issue, it means your O2 sensor is close to its wear limit and will need to come back for a replacement. Any questions feel free to get in touch on 01420 544433 or email us at info@testo.co.uk

Hi Simon, thank you for your question. There are instructions on how to do this in the user manual. If you are still having issues, please email info@testo.co.uk and we can send an easy guide to setting up the testo 310 to you.

Thank you for your query, yes R290 is a common refrigerant used with the 557s kit, which includes the 549i. Please let us know if you have any further queries.

Thank you for your query, are you located in the UK? We would like to get you in contact with the correct subsidary to get you the help you need!

Thank you for your query. With the dataloggers you have the option via software of setting an alarm value, if this alarm value is reached, then depending on the logger type you will get a prompt. With the 174 series an alarm breach is indicated on the LED screen by an arrow (up arrow for high alarm reached and down arrow for low alarm) and with the 175 series logger (as in the video) there is an LED on the front of the unit to also indicate the device is in alarm condition. We hope that helps to answer your question.

@@Testolimited dear sir thanks for your answer but I have an area where I want to keep 14 data loggers but data loggers is showing out it's temp and Rh range so is there any setting to fix the temperature on 1 particular fix limit suppose I want temperature and Rh in that area is 22 so it is fix on 22 or not....?

@@indianindian4617 Hello, apologies but we are not quite sure what it is you are asking. Are you located in the UK? If so you can provide us with a mobile number and a member of our team can give you a call to discuss. If you are not located in the UK please forward your query onto testo International at: info@testo.de and they should be able to help. Thank you.

Thank you for your query. The presenter of the video suggests using the testo 552i digital vacuum gauge for your vacuum test measurement rather than the 550s or 557s manifold. The reason for this is that the manifold sensors cannot measure vacuum with accuracy - we offer bundles of the 552i with the 557s for high accuracy vacuum measurement. However if needed the 552i can also be purchased as a separate item for use with the 550s and 550i manifolds. The 552i connects to the 550s or 557s manifolds via Bluetooth so that the manifold display can show the vacuum and other key parameters in a graphical form to enable quick assessment of the vacuuming of a system. It is also possible to link the 552i digital vacuum gauge directly to the Smart App as well so you don’t have to use a manifold. We hope that helps! If you have any further queries please do not hesitate to get in touch.

Thank you for your comment, are you using the hood or pitot tube for this measurement?

The testo 270 measures: Oil temperature & TPM = total polar materials. On our website you can find a field guide which explains why our device measures TPM and how this relates to other measurements such as FFA. We hope that helps. www.testo.com/en-UK/testo-270/p/0563-2750

Thank you for your query, please contact testo international via the details at: www.testo.com/en/ They will be able to help you with finding testo 310 sensors with your local subsidary. Thank you.

Good afternoon, thank you for your query. In order to perform a let-by test you will need to use the old testo smart probes app. Testo HQ are currently working on an update for the new testo Smart App to include let-by tests however this is still in progress. We hope that helps, thank you.

Hello, thank you for your query - If you go onto the app and connect the probe, then go to the basic view (under the measure menu), and click on the three dots. The second option is 'Zero Pressure Sensor' - click that and they should zero out. We hope that helps, please let us know if you have any further queries.

Just to add - if your batteries are too low this may not work, so please ensure that the batteries are fully charged. Thank you.

All pricing for testo thermal imaging cameras can be found on our website: www.testo.com/en-UK/products/thermal-imager pricing may vary between subsidaries so please be sure to check your country in the top left of the website. Thank you.

Thank you for your query, it shouldn’t need calibrating straight out of the box, however, when you have started using the unit it’s best to recalibrate on a regular basis, the more it’s recalibrated (depending on the amount of times it’s being used), the more accurate the results will be. Once a week or once a month etc. We hope that helps!

We are sorry to hear you were not entirely satisfied with our temperature clamps, if you would like us to investigate this further please provide us with your contact details or you can get in touch with the team at 01420 544433 or info@testo.co.uk.

@@Testolimited yah, I'm calling on Monday. Im fairly new to the AC side of the HVAC trade and I was so pummed with my new manifold and clamps. I absolutely love the 550s manifold, it's just the clamps I'm having a big problem with. I probably over charged a bunch of txv systems already. Recommend redesigning the clamps all together, best to go with the uei clamp design. Just a recommendation.

@@liljfk9314 Thank you for your response, we will pass your suggestions onto our product design team over at HQ.

Thank you for your query, the probe head is not interchangeable and unfortunately we don’t sell adaptors or fittings. You may be able to purchase fittings thorough your local refrigeration wholesaler that sells smart probes.
