Hot New Product!  Hand held Talking Infrared Thermometer:
cooking and safety aid for the blind

The IRT-1 Talking Thermometer was developed for use by the blind and poorly sighted primarily as a cooking aid, with a built in voice instructions as to its use.  The IRT-1 can be set to speak in English, Spanish or French.  More languages may be added in the future.

Note: any discounts mentioned in old podcasts are no longer in effect as the current price has been reduced.

Listen to the start up tutorial! (Actual IRT-1 sound file!)


  • Temperature range: -70 to 380 degrees Centigrade (-94 to 716 degrees Fahrenheit)
  • Powered by 2 AA batteries.  Battery life is expected to be 6 months on average.  Battery life is affected by usage, age of batteries, and quality of batteries as well.  Batteries are easily replaced at the back of the unit.
  • Low voltage detector:  The IRT-1 will speak "low battery" when voltages get too low.  The infrared sensor can give erratic readings if batteries are low.  The user should replace batteries as soon as possible upon hearing the low battery announcement.
  • Languages:  speaks English, Spanish, and French.
  • Unique scan function to locate hot objects.
Easy to use!!

Remove the ribbon from the battery compartment, which will power up the unit.  You'll be prompted to press any button to start the very short tutorial.  You will only hear this when first installing batteries.  From top to bottom there are 3 buttons: Temperature, Scan, and Mode.  The infrared temperature sensor is located at the top of the unit, above the speaker.  To measure the temperature of an object, hold the IRT-1 a short distance from the object and press the temperature button.  You'll hear the IRT-1 speak the temperature!  Be sure the sensor is pointed at the object.  Later you can change to Centigrade, or to your preferred language.  The IRT-1 defaults to English and Fahrenheit.  To locate a heat source, typically a warm or hot burner on a stove, press the middle button.  This is the Scan button.  As you move the IRT-1 back and forth across the hot object you will hear a beeping tone that goes from slow to fast.  Fast beeping indicates a hot temperature.  Great for locating a burner on a glass cook top stove, or to verify a pan is centered over a burner.  The Mode button (third button) allows you to change from Fahrenheit to Centigrade and back, or to select your preferred language.  When you press Mode you will hear brief instructions, which you can stop by pressing any button.  The Temperature button allows you to change from Fahrenheit to Centigrade, and the Scan button allows you to select language.  When finished with your selection press Mode again and the IRT-1 is ready to go!  For more details on usage please download the IRT-1 User Manual.

So, how does an Infrared Thermometer work, and how is it different from an ordinary thermometer?

Infrared energy is actually a form of light.  We can't see it, but we can feel it.  If you've felt heat from a hot stove or a campfire, for example, it is infrared energy we feel.  The IRT-1 has a device that can sense infrared energy (IR for short), much like a solar cell can detect energy from the sun.  When you point the IRT-1 at something and measure the temperature, you are measuring the infrared energy the object is radiating.  Just like your hot stove radiates heat, every object radiates a certain amount of IR energy.   If you measure the IR energy inside your refrigerator you might get a reading of 40 degrees for example.  This is because the objects inside your refrigerator are cooler, and radiate less IR energy.  It's important to know that an IR thermometer is different from other types.  For example, a meat thermometer will measure the temperature inside the chicken or steak you are cooking.  The IRT-1 will measure the surface temperature of the food you are cooking, or the temperature of the oil in the pan for example. The type of object affects the readings.  For example, trying to measure the outside of a shiny pan will probably give a rather low reading.  There isn't anything wrong with the IRT-1, it's just that shiny or reflective objects do not radiate thermal energy the same way as others.  For more usage tips and information about ways to use the IRT-1 please refer to the user manual, available as a download.
