Cooper Atkins SH66A FDA Digital Thermistor Thermometer -40 to 300°F

Cooper Atkins SH66A FDA Thermometer

The Cooper Atkins SH66A is a digital thermistor thermometer built for professionals who need verified accuracy across a broad temperature span. It covers -40 to 300 degrees Fahrenheit or -40 to 150 degrees Celsius with a resolution of .1 degrees. A NIST-traceable certificate is included, confirming the stated accuracy of +/- .3 degrees Fahrenheit or +/- .5 percent of reading, whichever is greater. The unit operates on a single 9V battery and features a 4-digit backlit LCD.

Food-safety teams and lab technicians

This instrument suits food-safety teams, HVAC technicians and laboratory staff who require documented calibration and a constant-scan function across three channels. The switchable Fahrenheit and Celsius display, min/max memory and temperature-trend indication support routine compliance checks. Buyers who need wireless data logging, more than three simultaneous probes or a waterproof housing should look at other models. The restricted-state list is empty, so no regional limitations apply.

Bundled NIST certificate and core functions

The included NIST-traceable certificate removes the extra cost and lead time of third-party calibration, letting the thermometer enter service immediately. Constant-scan mode cycles through all three channels automatically, while the low-battery indicator prevents unexpected downtime during shifts. Min/max memory and trend arrows give quick context without needing external recording tools. These features combine to reduce setup time for regulated temperature monitoring.
