Notable Features

Insulated thermocouple wire is suggested for measuring temperatures suitable to the wires characteristics. 

Stainless Steel Over Braid (SSOB) is used in applications that require mechanical and abrasion protection. SSOB is tough and flexible.

Thermocouple Grade Wire is wire that has been tested to meet the ASTM Standards.  If "K" thermocouple has a ±2°C specification it means when tested at specific temperatures it must be within 2°C / 4°F.  If you want to know a little more about how accurate the wire is must test at two known ( easily produced ) temperature points.

Ice Bath: 0°C / 32°F  
Boiling Water: 100°C / 212°F ( depending on elevation) 

The ice bath is the easiest test to create.

1.) Fill a vessel (such as our Styrofoam cup or SS flask ) all the way to the top with ice. Crushed ice is preferred because there are fewer gaps between the ice, however cubed ice will also work fine.

2.) Add Water - Slowly add water to fill the spaces between the ice. Fill about 1/2" below the top of the ice. Let the mixture sit for a minute or two to allow the temperature of the water to settle. If you see the ice starting to float off the bottom of the vessel, pour off some water and add more ice. Water below the ice will not be at 32°F. 

3.) Step Three: Insert the Probe
Once the mixture has rested for a minute or two, insert your probe (or thermometer stem) into the mixture and stir in the vertical center of the ice slurry. Stirring the probe keeps the sensor from resting against an ice cube, which will affect your reading. Keep the probe tip away from the side walls and don't allow it to rest against the bottom of the vessel. Doing so will give you inaccurate temperature readings. If the thermometer has an extremely fast and sensitive needle tip you MUST gently stir the probe or you will find colder and warmer spots in the ice bath. Stirring equilibrates the temperature throughout the vessel.

4.) Step Four: Confirm Calibration
Your thermometer should read 32°F (0°C) in the ice bath. If applicable adjust your dial thermometer as directed by the manufacturer; however, before you attempt to adjust a digital, instant-read thermometer, check that the readings are within the manufacturers accuracy specifications. (Look for a ±°F on the documentation included with the instrument.) If it's within the specified tolerance, don't adjust.  Additionally some instruments to not allow for adjustment and thats OK.  You NOW KNOW the error you are dealing with.
