Calibratable Dial Thermometer?

[Kieran the Human]

So my Digital Thermometer has packed it in, good riddance I say. I'm looking for a good Dial Thermometer that I can calibrate manual via a calibration nut (or whatever you call them) - I've been looking online and I can't get any info on whether or not the thermometer can be calibrated - had ordered one from the homebrewcompany but they sold out before the order was shipped.

Does anyone know of a good place to look?

ebay, get 2.

calibrate one at zero using a calibrated thermometer or a glass of water and ice, calibrate the other at 100 in gently boiling water.
use one for low temps like lagering and fementers and use the other for sparge temp and mash temp.
even the good food probe theremo's tend to be inaccurate over the 1-100 range and quite reliable if calibrated at more specific temps

heres an example that I use and its very reliable http://www.ebay.ie/itm/Stainless-Steel-Kitchen-Cooking-BBQ-Probe-Thermometer-120-C-/360767292865?pt=LH_DefaultDomain_0&hash=item53ff6805c1

if buying one from whereever online make sure the range is zero to 100c, most start at 75c to 300c...dont make that mistake

Sound man Bren, just ordered 2 of them there - great price

[brenmurph]

Hi Brendan

Does the thermometer you linked to have the ability to be calibrated? Could not find anythingv definite on the eBay link.

From the picture it has a nut behind the dial for calibration although it doesn't mention that in the description

[brenmurph]

correct you grab the nut with a pliers and turn the unit by hand.  Follow my first post re have atwo and you have a very accurate pair of gismos for about 5 dollars.

@ shiny
no batteries, no effect from water spashes, not affected by dropping and so on, great little gadgets and nothing really to go wrong they are solid state.

They can of course have their springs stretched by - 20's or oven temps they( in my link are zero to 100c so make sure to observe this

Cheers,  sounds like a great addition to ever increasing box of tricks.

Na sorry, I need to know my 68.4's from my 66.8's call it control freakery if you like.
And as I was in the scouts I always care a spare battery.

@ CH

John ya still need to calibrate a digital one :   and once calibrated they can be read to less than a degree

I still use pid's but I have  several thermos as back up including digital probes, prefer the analogue for their simplicity

On the topic of thermometers, I have always used one of those Mash Thermometer's with the protective cover to measure my mash temperature. Over the weekend I was experimenting with BIAB and happened to double check the mash temp with a glass spirit thermometer and i noticed that the two temperatures where different by a couple of degrees. Which one do you think would be the most accurate? Are the digital thermometers with the probe attached a better option for mash temp? Anybody any thoughts on this?

[Ciderhead]

They are both shite
Only joking new glass thermometers are the most accurate, but after several years of up and down that tube they aren't great. I have one only for calibrating which I do every couple of months
Big discussion about this here historically have a look in search.
