Fluke Contact Thermometers
Contact thermometers measure temperatures by coming into direct contact with objects under test. Fluke contact thermometers feature E, J, K, and T thermocouple temperature probe ports with better units featuring up to twelve thermocouple ports and even the smart INFO-CON port. Fluke contact thermometers can measure a variety of objects using different probe styles.
Configurations of Fluke Contact Thermometers to Consider
-
1 & 2 Channel Portable Thermometers. These Fluke Thermometers are designed for maximum portability and easy handheld use in any environment. These thermocouple-type thermometers are extremely affordable but are lab-accurate and made with signature Fluke quality.
-
4 Channel Benchtop Thermometers. These thermometers from Fluke Calibration are designed for lab use. Each unit features four input channels, PRT/thermistor/thermocouple sensor types, maximum accuracy of ± 0.0025 °C at 0 °C, and internal storage for up to 8,000 temperature readings. There are no better bench thermometers for the price.
-
Data Logging Thermometers. These digital thermometers store data and record it for future reference and analysis. Because of this, data logging thermometers are frequently used in laboratories, audits, and industrial control situations for measuring differential temperature. Fluke data logging thermometers also come with included software for easy data transfer and analysis on your PC. Fluke data logging thermometers can store from 500 readings up to 15,000 readings internally on the best units.
-
Infrared Thermometers. Some non-contact IR thermometers can also be used as contact thermometers. They come with temperature probes for contact readings. The Fluke 560 and 570 series of IR thermometers incorporate contact measurement capabilities via K-type thermocouple probes.
-
Intrinsically-Safe Reference Thermometers. Fluke reference thermometers are designed to give the user accurate and consistent temperature readings wherever they are needed. These portable thermometers are extremely accurate to ± 0.05 °C and feature data logging and NIST calibration. These are hands-down the best alternatives to mercury-based reference thermometers because they don't contain mercury and maintain their accuracy at any temperature regardless of application.

Temperature Probes. Temperature probes are metal thermometers used to measure the temperature of a specific environment, such as a piece of meat or a liquid. They are often used in food preparations and laboratories. Many accessories are available, and they come in a variety of styles and sizes to meet a range of needs. T-handle temperature probes make it easier to hold while jabbing. Bead type temperature probes can be snaked around objects. Half-pipe shaped temperature probes fit around the circumference of pipes. When choosing a temperature probe, it is important to consider how the device will be used.

High Accuracy Secondary Thermometers vs. Primary Contact Thermometers
There are two main types of thermometers: primary and secondary. Which category the thermometer fits in depends on how the temperature measurement is calculated.
The most common type is high accuracy secondary thermometers. They are widely used because of their convenience and accuracy. These types of thermometers must be calibrated against a primary thermometer.
Primary thermometers are more complex than secondary thermometers. These thermometers calculate temperature without any unknown quantities because the measured matter is so well known. For instance, these thermometers may be based on the equation of the state of a gas, on the velocity of sound in a gas, on the thermal noise, or other complex equations.
