no worries. Actually, if I had an hourglass it would look really good perched on top of the oven. Thanks for the idea. I might look for one. I've been through all the temp measuring devices. I have a thermometer in the side of my oven another hole on the other side to take a kiln probe that has a porcelain sheath which is connected to an anologue (unpowered) read out gauge, an infrared gun and an internal air temp thermometer as well as a thermometer you stab into a joint of meat or loaf of bread. Increasingly use all of them less the more I cook. There is another trick apart from the semolina on the floor that the Italians used to use and that is to hold your fist in the centre of the oven until you have to take it out. 0 secs= pizza 1 sec= v hot ( roast Vegas, calzones 2-3 secs = foccacias, roast meats 4 secs = bread,puff pastry, general baking 6-7 scones, desserts etc. many = slow rost meats,drying etc.

That is some great info about the tubing. I need to replace a thermocouple and while I was there I figured I would add a well. Mine are just inserted in the mortar joint, so good to know about the SS. Thanks

Richc,
Sorry I miss this question. Yes that meter does take a type K probe.

KB,

I did use 3/8" 316 SS tubing I picked up as scrap. I place on probe at 1/2" from the inside of the brick and the other abt 1/2" from the outside of the brick. My plan for the TCs were to monitor brick heat saturation for future baking. Since I have barely finished the final coating of the oven I have not measured temperatures other than confirm the TCs work. I did not think it was worth while to monitor until all the insulation was on. I just use a laser gun for my pizza but starting to get a feel on how hot the floor is without the gun.

Great placement Russell, With those two numbers alone you can tell where to stop your firing to hit your desired oven temp after the resting period. Just average the two numbers and that should be your total saturation temperature.

I'm thinking of buying this IR thermometer……..I need everyone’s opinion. Do you like it? Is the range high enough? If you know of a better one or better deal post the address, thanks all.

I've got one almost exactly the same, but it's called ThermoWorks, but has the same range.It very easily "tops out". Don't forget that an IR only reads the surface temp so will record a higher temp than the oven really is at. The laser pointer on mine has died by the way, but it is independent of the temp measuring sensor so it still works.
