Calibrated Glass Lab Thermometer with Certificate - Made in USA - Kessler

This "Precision SafetyBLUE Thermometer" is made in the USA by Kessler Thermometer.  This version includes a Calibration Certificate with a calibration made at 152°.  This allows you to have a thermometer that is on exactly in the "mash temp" range. For example, we have one of these in our office and the certificate states that when our thermometer reads 152.2 the temperature is exactly 152°.  This also allows you the ability to calibrate other types of thermometers and temperature probes in your brewing systems.   Click here to see an example of the Calibration Certificate you will receive with this thermometer.

It is a professional grade lab thermometer (vs a classroom thermometer) which will provide the most accurate and precise readings.  Kessler utilizes their proprietary internal liquid which contains no Mercury, but has weight properties similar to give the most accuracy possible.  We also offer a calibrated version of this thermometer.  KesslerUSA is ISO 17025-2005 and ISO9001-2008 accredited and is a member of the ASTM committee on Hydrometers and Thermometers.  For the serious brewer this is the thermometer you want!
