Precious Metal Thermocouples

Precision temperature consistency allows our precious metal thermocouples to make repeatable manufacturing processes a reality, delivering consistent products to your customers. Our thermocouples are known for reliability and quality in the semiconductor industry.

Make the Most of Limited Lifespan

Drift happens, but it’s virtually undetectable from outside the process. Because of this, all thermocouples have a limited lifespan and are replaced periodically. Honeywell thermocouples are calibrated to correctly replace your originals. Our precision calibration methods directly compare your thermocouples to Industry standards.

Redesign with Honeywell

To extend the lifespan of thermocouples, our experts can collaborate directly with equipment makers to redesign and re-engineer thermocouples Please Contact us for more info about working together.

Precision temperature measurement

Our 99% customer acceptance rate, high quality and accurate calibration can help reduce downtime in your processing applications. We use premium grade wires in our thermocouples, which ensure tighter temperature control and lower deviation between lots to help you maintain a higher repeatability rate.

Profile Thermocouples

Profile Thermocouples are essential for characterization of diffusion furnace process tubes. HEM custom manufactures thermocouples to fit every furnace type and requirement

Spike Thermocouples

Spike Thermocouples serve the critical control function in diffusion furnace processes. HEM manufactures spikes to OEM specifications. We can help you design custom spikes to meet specific temperature requirements.

Applications

Profile and spike thermocouples are vital components used to measure temperature in diffusion, Low-pressure Chemical Vapor Deposition (LPCVD) and Directional Solidification System (DSS) furnaces manufactured by OEMs. Calibrated thermocouples are used in conjunction with spikes for furnace characterization and control.

Precision Calibration

Because we understand how critical accuracy and repeatability are to your business, Honeywell Electronic Materials (HEM) uses the Direct Comparison Calibration Method. We compare your thermocouple to a master reference in accordance with National Institute of Standards and Technology (NIST) or the United Kingdom Accreditation Service (UKAS) traceable standards. Each junction is calibrated individually using our proprietary software.

Our facility includes five custom-designed comparison calibration furnaces and four freeze point calibration furnaces all housed in a temperature and humidity controlled room.

HEM provides expert calibration services in our facility in Yaita, Japan.

Secure calibration data is available online, 24 hours, 7 days a week.

Contact Us to see how we can design a custom thermocouple configuration specifically to your manufacturing requirements.

Manufactured to OEM certified specifications

Our thermocouples are provided with offsets from our precision calibration system. Our system is directly traceable to the National Institute of Standards & Technology (NIST) or the United Kingdom Accreditation Service (UKAS). HEM supplies thermocouples to thermal processing equipment manufacturers for Low Pressure Chemical Vapor Deposition (LPCVD), oxidation and other processes.

Metals Reclamation – Thermocouples Exchange (SWAP) program

Each thermocouple contains precious metal that you can leverage. Honeywell Electronic Materials (HEM) offers a SWAP program that allows your business to trade-in used thermocouples for brand new ones without the need for scrap credits. Our standard service provides customers the convenience of instant metal credit.

With the Honeywell SWAP progam, you get a new thermocouple every time which ensures that there are no homogeneity problems from used wires. It’s also a very flexible program – you can exchange one type of thermocouple for any other.

For more information about how you can take advantage of our SWAP program and keep the same price for an extended period of time (1+ years) without being affected by the precious metal market fluctuation please Contact us.

Recalibration and Repair

Our repair and recalibration service is a complete evaluation of a thermocouple for breakage, contamination and wire damage. New junctions are formed and the wire is calibrated in our proprietary calibration system. We reassemble the thermocouple with new parts as needed.

Each thermocouple goes through a rigorous final inspection, which includes electrical testing. Finally, individual thermocouples are sealed in plastic and placed in our custom packaging.
