[Sold] - High temp IR thermometer - 1600F
« on: August 14, 2009, 12:25:10 AM »
Thinking of getting an IR thermometer to measure your oven temperatures? You can buy some models that measure 900F or so for about $60. Or you might be interested in this one that can measure up to 1600F. It's really overkill, you don't need a thermometer that goes this high, but I'm selling it at a bargain price if anyone wants a more robust thermometer. One nice thing about this one is that it goes high enough to measure a lot of oven dome temperatures as well as the deck. Usually the dome is way over 1000F, so most guns can't measure temps that high.

This thermometer works perfectly, has never had any issues and comes with the factory manual. It does show normal wear, some scuffs & scratches, but nothing that keeps it from working properly. It has an ultra bright pointing laser built in, so it puts a laser circle at the exact point where it is measuring the temperature. It's got a bunch of features built in, min max alarms, graphing recent measurements, adjustable emissivity, etc. But just point & pull the trigger to read a temperature. List price (new) is $779. Really. This model is meant for industrial use (steel mills, electricians, etc) & is not a cheap knockoff. The manufacturer (Raytek) just got bought out by Fluke who has changed the thermometer color to yellow & raised the price to $830. But it has the same features & specs as this one.

My employer owns the same model that I have & I have free access to it, so mine has just been collecting dust. So if anyone here is interested, I'm looking for $145 + actual shipping cost. Paypal. Probably $10 - $15 would get it shipped to you by priority mail, with insurance & a tracking number. If there is no interest, then I'll probably put it on Ebay for $200. Here's some specs, compared to the Harbor freight one (which is also a decent choice, if you want to spend less money).

A few pictures. The red dot in the third photo is the built in laser pointer. The last photo shows the IR thermometer for sale to the brand new one from work. Both read the same temperature for a given spot.

What a DEAL!  I have that same model.  It can be programed for varying things like hot food, brick, basalt.
Not a lot of basalt around here but it comes in handy for food prep.  While vigorously stirring a hot liquid like soup stock or an ice cream base, point the beam at non-foaming, churning area, you will get an accurate temperature without contacting the food.  The display runs a linear sampling bar which shows the current (real time) temps. as it sees them.  I also have one of those cheap $40 handhelds.  A head to head showed greater inaccuracies as the temps climbed.  It's only use now is to take it to big chain grocery stores and shine it on the refrigerated cases and pretend to write stuff down on a clipboard.  All the time looking very concerned.  Huge pucker factor.
The Raytek Raynger MX is a true scientific instrument but has a cool factor that pegs the needle.
If you get no bites here, show it on Forno Bravo.

When I first got mine, I pointed it at everything. What I really use it for is oven temps & sometimes wine or sausage making. But when I'm bored you can tell what cycle the dishwasher is on or whether your fridge is doing an auto defrost at the moment from across the room as the shell temperatures vary a few degrees. You can make a pretty good guess at how long a car across the street has been parked. The cats go crazy chasing the circle of laser dots on the floor. And the occasional airframe mechanic might try to talk you out of it.

I've found this model dead on for repeatability. The calibration is non-linear though. What that means is that the 0.75% accuracy is concentrated at one end of the temperature range. So it's something like 0.25% accurate at one end & perhaps ~ 1% at the other end of the overall range. The range is -25F to 1600F. For this gun I had the high end calibrated. I'm not interested in snow temperatures or absolute accuracy for air conditioners or ice cream making. So it was set up for optimal accuracy at oven temperatures at the expense of room temperature & lower being a couple of degrees off.
