Digital Thermometer for greenhouse?

LeadFarmer

Anyone able to recommend a digital thermometer suitable for use in a greenhouse please?

There are loads on Amazon, but all with mixed reviews, with units often failing.
Would like min & max temperatures to be displayed.
Thanks.

I’ve got a couple of Brannan digital display thermometers which show max/min and current temperatures. Had them for several years without any problem. Handy in the greenhouse for knowing how low the temperature dropped overnight.

Hi there. This one's been fine for last couple of years.

I've got an ancient mercury max/min thermometer that does all that and nothing to go wrong unless I drop it

I didn’t drop my old one, it was treated well, but once it began refusing to acknowledge that the lowest temperature last night had not been 35C it finally had to go.

Had one of these for a while and seems to do the job well: https://smile.amazon.co.uk/gp/product/B00QNTX1HQ/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

I’ve used this one in my greenhouse for the last year, and have been pleased with it.  Think I got it after a recommendation on here on a thread at the time (March 2021)

edited to add:  found the thread from last year here …..might be of some use …

I bought a Brannan one (or very similar) (see @helios recommendation) for my FIL to use in their conservatory. Picked that one because he had cataracts and needed a clear, large display and simple controls. Five or six years later it's still working well.

I have a Techno line weather station with a sensor on the garage wall and another in the potting shed. Means I can see the temp and humidity in the shed and outside from the comfort of my desk. Can also reset the max / min readings for both without setting foot outside. Very useful when it's persisting down.... I've had it for about 10 years and it's been reliable except when the batteries are running low. Cost a bit more than the Brannan though!

Thanks everyone. I've decided to order this one to try..
