## Questions & Answers

**Q: Does it need batteries?**
A: No.  It's Just a thermometer showing the current temperature and the minimum and maximum temperatures that have been reached since it was last set.  You set it by pressing on the black button in the middle.

**Q: What is the item made of?**
A: Metal casing.  Glass thermometer.

**Q: What are the dimensions of the thermometer please? (The Amazon details give only the dimensions of the package.)**
A: Hello.  Measurements are 22x5x2.3 cm.  I have two. An older Mercury filled one and a new spirit filled one.  The mercury filled ones are much easier to read but I'm not sure you can get them any more.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good quality max-min thermometer
  

*by B***L on Reviewed in the United Kingdom on 14 February 2019*

I like its appearance and its sturdiness.  It works much better than the Brennan equivalent that it replaced.  The first Herter had suffered some shocks in transit, resulting in some bubbles that I couldn't shift, despite excellent help from the manufacturer's customer service people.  Amazon provided a replacement which was bubble free.If I could change anything, it would be the size of the screw holes for mounting it.  They are a tight fit over the heads of the appropriate sized screws.

    markers stuck
  

*by T***M on Reviewed in the United Kingdom on 11 February 2019*

Very pleased initially but the markers are stuck after just over a month in use. Occasionally they spontaneously release too rendering the thermometer unfit for purpose.

    Maximum /minimum thermometer
  

*by W***N on Reviewed in the United Kingdom on 17 May 2021*

When I take the temperature readings from the previous 24 hrs it is difficult to shake the indices down to the current temperature..I have to shake the thermometer in my hand.The button press does not work 🙁 it is very frustrating.
