The glass tubes are always far too delicate, and more often than not they break too easily. I've bought several Brannan products over the years, and they have all been excellent quality, and very accurate, so when I saw this rather attractive round needle thermometer, I thought I might give one a test run. The rear casing is made from good quality ABS plastic, if it was metal then the metal coils that react to temperature change would give an inaccurate reading. The main body of the thermometer is a nice metal bronze antique style affair, very clear to read, and the three hands,coloured black,red and blue are also made of metal. Setting both Hi & Low temperature needles is very straight forward, but the main black temperature needle gives a surprisingly accurate reading, that due to its design takes quite a while to settle. That is a good thing, because you know the temperature is being measured carefully. Even the small humidity gauge beneath, responds slowly, and quite accurately as well,compared to the very accurate digital Oregan Scientific weather station on my wall, it works well considering it's a very basic leaf spring construction. Without having seen this temperature gauge in the flesh before purchasing it, there was always a risk that the £13 had been too much to pay, after all it does look very nice in the photographs, but thankfully it represents very good value for money, and above all it's very accurate and if cared for properly should last many years. Always a risk buying a product without seeing it first, but it turns out this was money very well spent. Review: Reliable thermometer. - Very good thermometer for my tomato growing greenhouse.

It looks beautiful, but I don't see the diameter written anywhere!** A: Diameter is just under 100mm (4inches) and depth/thickness is about 40mm (1.5inches) including the knurled adjustment knobs on the front. **Q: CAN THE UNIT BE MOUNTED FOR OUTDOOR USE?** A: Hi Stewart, I'm not overly impressed with this product as I find the min and max needles stiff and awkward to reset. As to your question.... I have mine mounted under my car port as not confident of it being water proof. Doesn't appear to be that accurate either but that may be due to it's frost protected position underneath the car port. Product instructions didn't seem to suggest that it's rain proof and has open slots in outer casing. **Q: What happens if the temperature goes above 50°C as I live outside the UK and temperatures often go above this threshold so I am worried this breaks?** A: ok ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice Quality & Surprisingly Accurate Well Worth the Money *by M***S on 14 October 2013* Over the years I purchased quite a few Hi Low Temperature Thermometers, all of which have been the now discontinued mercury style affairs.

Very accurate. ### ⭐⭐⭐⭐ Seems fine to me. *by J***L on 2 May 2022* Bought to replace a long line of modern liquid min/max thermometers (not the old mercury ones) which end up with the liquids mixing or bleaching in sunlight after a short period of use. I was put off by the bad reviews, but have no problem setting the min and max needles by hand after reading the instruction. Seems tolerably accurate, (how do you know if it's a couple of degrees out unless you have a calibrated and certified thermometer to compare it with?), and the plants won't die if it's a couple of degrees out anyway. Really easy to read from outside the greenhouse, and looks good. Better than many thermometers on sale in this price range. ## Frequently Bought Together - Max Min Thermometer and Hygrometer - Ideal Greenhouse Thermometer and Humidity Meter to Monitor Maximum and Minimum Temperatures and Humidity Easily Wall Mounted - AcuRite 5" Capacity Easy-to-Read Magnifying Acrylic, Blue (00850A3) Rain Gauge - Mateda 7" Capacity Rain Gauge with Stainless Steel Mounting Rack Holder, Post Mount Rain Gauge for Yard Garden Outdoor Home (Style A) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/52625673-brannan-max-min-thermometer-and-hygrometer-ideal-greenhouse-thermometer-humidity](https://www.desertcart.us/products/52625673-brannan-max-min-thermometer-and-hygrometer-ideal-greenhouse-thermometer-humidity) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-06*
