Accurate Thermal Systems

Accurate Thermal Systems

Accurate Thermal Systems is a manufacturer of temperature calibration equipment, best known for its ThermCal series of dry block calibrators and fluidized bath systems. The company produces portable and bench-top calibration instruments designed for calibrating RTDs, thermocouples, thermistors, and temperature transmitters across a broad temperature range in both laboratory and field environments.

Dry block calibrators from Accurate Thermal Systems use a precision-heated or cooled metal insert block to provide a stable and uniform temperature reference without the need for calibration liquids. Their fluidized bath systems offer superior temperature uniformity by suspending sensors in a fine alumina powder medium, making them suitable for calibrating both standard and non-standard probe geometries.

Key Product Lines

• ThermCal400 Dry Block Calibrators — portable temperature calibration sources for RTDs and thermocouples
• Bench-Top Dry Block Calibrators — laboratory units for in-house sensor calibration
• Fluidized Bath Calibrators — high-uniformity baths using fluidized alumina for accurate immersion calibration

Industries Served

Accurate Thermal Systems calibrators are used in accredited calibration laboratories, pharmaceutical and chemical processing plants, oil & gas facilities, power generation, and industrial manufacturing where regular sensor calibration and process temperature verification are required.
