Lab Manager's Tip

Before ordering, verify which insert is included or must be selected. For accredited calibration work, the dry well alone does not establish traceability; follow your documented procedure and use an appropriately calibrated reference thermometer when required.

Typical Applications

Thermometer verification, temperature-probe comparison, thermal-switch checks, laboratory instrument maintenance, and field calibration support.
