5-star reviews“Helpful staff and great products” 

5-star reviews“Brilliant equipment & service. Thanks very much Hanna, a job well done.” 

5-star reviews“Excellent service, fast delivery. Should have bought from them years ago!” 

5-star reviews"My HALO probe stopped working. Without any issue, I was sent a returns form and the probe was returned to me under warranty as the tip was faulty. I feel that is particularly good service considering the probe was well used, and over a year after I purchased it, the company replaced it without issue. Then the replacement probe, unfortunately, appears to have a fault in that water got into it on its first outing. Again, I was provided with a free returns form and in less than a week I have been issued with a replacement after the engineers inspected it. Very good service indeed.

 "Regarding the HALO probe itself, I have found it to be an accurate and very helpful tool in the kitchen/bakery and as such I am very grateful to you.

 "All staff members that I have dealt with have been professional and polite and it has been a pleasure dealing with you all at Hanna."



About our webinars . . .

Wendy said: “The presenter has a great voice - no umming, no stammering - many podcasts are full of that.

“It was really interesting - I had no idea about the different materials and construction, nor how it actually measured the pH! And I appreciated the examples like cool Scottish mineral water vs a hot curry (that was quite funny - the spice vs temperature!) And it answered my question why there are so many types and prices of pH meters.

“I'm learning a lot – I am not a chemistry expert so it was all fascinating. And the speaker is really good at doing this. Slides are excellent too, lovely and clear and enables the noobs like me to keep up . . . he must really know his stuff to be able to explain it in plain English!”

Eddie: “I am quickly writing this to say the pH webinar I just attended was extremely good, very clear, and made the manual so much more understandable. 10/10 likely to recommend. Thank you and well done. Cheers.”

Luke: “Hi, Just watched your webinar regarding, pH best practice - look after your electrode. Short and informative. Enjoyed it, thanks."

Nigel: “Found the webinar very useful and gave me a good platform on how to approach calibration schedule for our pH meters. The 20 min duration was great as it was informative and not time consuming.”
