SPST Thermometer Tester
The SPST (Surface-Probe-Surface-Tympanic) Thermometer Tester is a cutting-edge solution designed specifically for biomedical engineers conducting in-field and on-site testing of thermometers used on humans. This innovative device features two advanced blackbody radiators, which serve as an infrared source, along with a central testing port that enables direct probe-style thermometer assessment through heat conduction.

Key Features
High Accuracy
The SPST utilizes blackbody radiators with a near-perfect emissivity ratio to provide a constant infrared radiation source, ensuring highly accurate temperature regulation during testing.
Rapid Functionality Verification
The unit can verify the operational efficiency of thermometers in just seconds, making it a time-efficient tool for professionals.
User-Friendly Design
With its portable battery-operated structure, the SPST is easy to use and transport, allowing engineers to perform tests wherever needed.
Versatile Testing Modes:
The device includes an option for Tympanic mode, allowing for comprehensive testing of tympanic thermometers with the use of Tympanic Adaptors (available with the appropriate firmware version).
With the SPST Thermometer Tester, biomedical engineers can confidently ensure the accuracy of thermometers, enhancing patient safety and measurement reliability.
