TEST PRODUCTS INTERNATIONAL 310C 4.9" Stem Digital Pocket Thermometer -58°F to 300°F

Digital Pocket Thermometer 310C

The TEST PRODUCTS INTERNATIONAL 310C is a side-reading T-handle thermometer built for quick temperature checks in food service, HVAC and general maintenance. Its 4.9 inch stem reaches into ducts, liquids or stacked product while the 10 mm LCD digits stay visible at a glance. The range covers -58 to 300 degrees Fahrenheit and -50 to 150 degrees Celsius with a stated accuracy of plus or minus 2 degrees Fahrenheit or 1 degree Celsius. It suits technicians who need a compact, immediate reading without a folding mechanism.

Build Integration & Workflow

The rigid T-handle body fits in a shirt pocket or tool bag and requires no external power beyond its internal battery, freeing both hands for probe placement. Because the stem does not fold, the instrument maintains a fixed 4.9 inch insertion depth, so the user must ensure that length suits the target environment. The side-reading display lets the operator view the temperature while the stem is engaged, reducing the need to withdraw the probe to check the value. No mounting hardware or cable routing is involved.

Included Certificate Impact

A NIST-traceable calibration certificate is not included with this model, so users who require documented traceability for audits or quality systems must arrange separate certification. The absence of that certificate keeps the initial cost lower and simplifies deployment for non-regulated tasks such as quick spot checks or internal process monitoring. The unit carries no NSF rating, limiting its use in certain commercial food programs that mandate listed equipment.
