Compost Thermometer - Stainless Steel Probe - Colour Coded Temperature Guide - 50mm Dial and 500mm Stem - Home Gardening Tool

Great worked as it should, I love the colour coding, able to take a quick reading at a glance. Fab

Works Perfectly, Very easy to use straight out the box. Extra long to get deep into the compost heap for testing temperature.

Compost temperature display clarity is ok , digits are small for older eyes but you soon simply use the colour banding.Nice long probe. It isn’t sturdy but with handling care this is fine.

Works well, appears quite sensitive and is easy to read

Good value and as described.

Great... easy to use and does what it says on the tin!

Ideal for checking if your compost heap is working . Simple to use and convenient gauge with easy to read information.

The length is really useful - especially when you are trying to check the core temperature of a conventional (1m cubed or more) compost heap, or something like a HotBin.My one reads about 5-10°C low, but I suspect that as this is not really a high-precision device, you will take pot-luck on how accurate yours is.As long as you calibrate it with ice-water and boiling water, you should get a rough idea how far out the thermometer is.Once you know that, it's no problem to obtain the readings you need. :)A downside is that there will be moisture ingress around the glass and the tube joint at the back of the head.This means you cannot leave it out in the rain (or inside a compost bin) without it getting bad condensation in the observation window.If you have access to a thin capillary sealant (like that used for windscreen repair), you can apply that around the glass and the body to keep the water out.It also works on the crimped rod seal at the back, but I would suggest the use of something the Furnox LS-X silicone jointing compound for that.At a push, you can *carefully* work LS-X under the glass/metal seal at the front with a thumb or finger.Careful though, the glass is VERY THIN!The other thing I would suggest is that if it is not in continuous use, that you keep the plastic an card container that it came in.This has saved mine from damage on more than one occasion - it does tend to roll rather well off a table...Very pleased with purchase, but wish it was waterproofed during manufacture.
