Traceable® Platinum Ultra-Accurate Digital Thermometer with Stainless Steel Probe

The Traceable Scientific Single-Input RTD Thermometer with Penetration Probe delivers exceptional temperature measurement accuracy for laboratory, industrial, and quality control applications. Featuring a high-precision resistance temperature detector (RTD), this digital thermometer provides reliable measurements across a wide temperature range of -200°C to 500°C (-328°F to 932°F), with a specified accuracy of ±0.05°C between -80°C and 100°C.

Designed for demanding laboratory environments, the TM-6412 combines a fast-response stainless steel penetration probe, selectable high-resolution digital display, onboard data logging, and USB connectivity. Each thermometer includes an individually numbered NIST-traceable calibration certificate issued by Traceable's A2LA-accredited ISO/IEC 17025 calibration laboratory, making it an excellent choice for facilities requiring documented temperature measurements and traceability.

Lab Manager’s Tip

For laboratories performing temperature-sensitive testing, the TM-6412 offers excellent measurement resolution and documented calibration traceability. However, display resolution and instrument accuracy should not be confused with the total measurement uncertainty of the complete thermometer and probe system.

For applications such as laboratory water bath verification, temperature-controlled conditioning, or reference temperature checks, confirm that the supplied calibration certificate documents performance at temperatures relevant to your testing procedures.

When working at critical temperatures such as 25°C or 60°C, consider requesting a custom multi-point calibration at those specific temperatures. Availability, pricing, and the uncertainty reported for each point should be confirmed with the calibration provider before ordering.

For best measurement performance, calibrate the RTD probe together with the meter as a complete system, particularly after replacing the probe.

The included certificate provides valuable traceability documentation, but laboratories operating under ISO/IEC 17025 should also evaluate measurement uncertainty, calibration intervals, and their specific method requirements before designating the instrument as a reference thermometer.
