Compact temperature logger for HVAC diagnostics

The SUPCO SL300T records temperature across a range of -40 to 160 degrees Fahrenheit. It captures dew point values from -40 to 185 degrees Fahrenheit. A digital display and audible alert provide immediate status feedback. The device samples data at a minimum rate of one second.

Digital display and audible alert improve field use

The built-in screen shows readings without an external device. An audible alarm signals when thresholds are crossed. These features allow technicians to monitor conditions in real time during service calls. No calibration certificate is included with the unit.

Operating range of -40 to 160 degrees Fahrenheit

This span covers common refrigeration and heating applications. The logger also measures dew point up to 185 degrees Fahrenheit. Buyers who need a wider temperature span or certified calibration should verify requirements before purchase. The unit is designed for single-phase environments.

Questions about this item

Will the SL300T data logger require periodic recalibration or battery replacement to maintain accurate temperature logging?

The logger is supplied without a calibration certificate, so periodic recalibration is recommended for critical applications; battery replacement timing depends on sampling rate and alert usage.

What is the highest temperature the SL300T can record before the sensor reaches its measurement ceiling?

The device logs up to 160 °F for temperature and 185 °F for dew point; sustained exposure above those limits stops further recording.

How much audible alert noise and self-heating should I expect when the SL300T runs continuously at a one-second sampling rate?

The unit emits a digital-display sound alert only when thresholds are crossed; continuous logging at one-second intervals produces negligible self-heating and no constant fan noise.
