The Check-Set four thermometer calibrator manufactured
in Rochester New York USA by Tel-Tru
Manufacturing Company provides constant temperatures
for verification and calibration
of your temperature probes The Check-Set four is specifically optimized for the dairy
industry
because its four set points that are offered 40
150 161 175 degrees Fahrenheit
this calibrating reference device is very simple to use
with an on and off toggle button an on switch for the set points
and a green light that will go on when the unit is ready for use
each unit is shipped with replaceable insert
well to allow the testing of a wide range a thermometer stem diameters
and the standard well has three bores 3/8
3/16 and 1/4 inch each unit is certified
serialized and NIST traceable The Check-Set four has precision accuracy of
plus or minus 0.2 degrees Fahrenheit
and its accuracy is superior to competitive products that cost
two to four times more in contrast to the ice bath method
you don't have to worry about staying with your verification process to make
sure the ice doesn't melt before you've completed the calibration process
here's an example of a bimetal thermometer put into the quarter inch
diameter hole
you can see that the indicating pointer is increasing
and a temperature setpoint is 161 degrees Fahrenheit
you now have the freedom to step away
and complete another task while your thermometers in the calibrator
with no worries about whether the ice is melting
or improperly causing temperature measurement error after approximately
three minutes
you will see that the thermometer under test has
accurately reach the selected temperature setpoint you would
recalibrate a thermometer
that does not accurately reflect the proper temperature setpoint we offer
carrying strap to allow you to bring the unit into the
plant processing area and validate thermometers on-site
currently many the plants are using an ice bucket
which can get very heavy and again if you get an interruption
you do have to worry about whether the ice bath is at temperature
we also offer additional insert wells that allow you flexibility for testing
different types of thermometers
and different stem diameters contact us for more information
we look forward to serving your need for simple
accurate and cost-effective thermometer calibration thank you for viewing
