ThermoWorks IR-Gun-S Review

The ThermoWorks IR-Gun-S is an infrared themometer with a few interesting features that set it apart from most other products of this type. Like most IR thermometers, it records the temperature in a cone in front of the sensor whose size is proportional to the distance from the gun. Think of htis cone as the field of view in a camera lens. Many are wide angles – the circle of measurement might be 1:4, meaning that the circle would be one foot in diamter at four feet from the gun. This unit is more like a telephoto where the ratio is 1:12, so the circle is one foot in diameter at 12 feet from the gun. This tighter cone makes it easier to narrow the area where the measurement is taken, excluding other surfaces that surround the target area.

There is a mode button that allows the user to view the minimum, maximum, difference, or average temperature detected during one pull on the trigger. One can also set high and low alarm thresholds that trigger an audible signal if the measured temperature is above or below the settings. Pressing the mode button after the unit shuts off will recall the last set of measurements. You can even put the unit into continuous measurement mode that doesn’t require a trigger pull – a handy feature if you want to capture a maximum or minimum temperature. One can also easily adjust the emissivity settings (if you know what you’re doing!) and change between Fahrenheit and Celsius scales. The backlight can be switched on and off to enhance low light visibility or save battery power.

The manufacturer’s contact information, including address, telephone and website, is found on the instruction sheet. There is no explicitly stated warranty, but our experience with this company indicates that they stand solidly behind their products.

We don’t have the equipment to test the accuracy of this type of thermometer, but they aren’t intended for highly accurate readings anyway. We give this unit a Gold medal for ease of use and features not found on most IR guns.

The Good-One Is A Superb Grill And A Superb Smoker All In One


The Good-One Open Range is dramatically different from a traditional offset smoker. By placing the heat source behind and under the smokebox instead of off to the side, Open Range produces even temperature from left to right, something almost impossible to achieve with a standard barrel shaped offset.

The Pit Barrel Cooker May Be Too Easy


The PBC has a rabid cult following for good reason. It is absolutely positively without a doubt the best bargain on a smoker in the world. Period. This baby will cook circles around the cheap offset sideways barrel smokers because temperature control is so much easier.

The Cool Kettle With The Hinged Hood We Always Wanted


Napoleon’s 22″ Pro Cart Charcoal Kettle Grill puts a few spins on the familiar kettle design. In fact, the hinged lid with a handle on the front, spins in a rotary motion 180 degrees. It’s hard to beat a Weber kettle, but Napoleon holds its own and adds some unique features to make the 22″ Pro Cart a viable alternative.

Masterbuilt MPS 340/G ThermoTemp XL Propane Smoker


This is the first propane smoker with a thermostat, making this baby foolproof. Set ThermoTemp’s dial from 175° to 350°F and the thermostat inside will adjust the burner just like an indoor kitchen oven. All you need to do is add wood to the tray above the burner to start smokin’.

Griddle And Deep Fryer In One


The flat top does the burgers and the fryer does the fries. Use the griddle for bacon, eggs, and home fries. Or pancakes, fajitas, grilled cheese, you name it. Why stink up the house deep frying and spatter all over? Do your fried chicken and calamari outside. Blackstone’s Rangetop Combo With Deep Fryer does it all!
