Customer Reviews

  Portable and discreet  Very useful for measuring beer temparatures in pubs as part of CAMRA beer quality surveys - this can be done discreetly without attracting attention. I like it a lot.   Simon - Aylesbury

  Excellent product and excellent service     -

    This company is fab first time I have used them Would reccomend. Lady on phone was very helpful.My order came the next day less than 24 hours after placing it. shame all companys I deal with arent like this   karen - newcastle upon tyne

  accurate and convenient to use  Does what is claimed; checked calibration on receipt - seems spot on. Very useful for general culinary purposes - I use it mostly for water temp. in bread-making. A detached probe would be more comfortable for jam-making! - but a glove helps. Slightly odd aesthetic and colour; very good value.   Mike Baker - Colchester

  Great Product,Great Price.  What more can I say ? Great Service too. Tidy little tool.   Nigel Portman - South Wales.

  Brilliant Service  Got this to carry out tap temperature test. Quick Service no problem.    -

   Robust, easy to use and clear to read thermometer  Compact, easily sterilised unit, that displays current value or maximum temperature reached via memory recall. Fully submersible design that responds to temperature changes quickly. For my intended use, it would have been helpful if minimum temperature reached was also able to be recalled.   Paul Kendall - Dereham, Norfolk, UK
