We produce a diverse selection of industrial thermocouples designed for temperature measurement in challenging environments. We offer all standard types, including Type K, J, T, N, R, and S, along with options for mineral-insulated, heavy-duty, and custom assemblies tailored to specific applications.

Thermocouples can be manufactured according to customer specifications, including equivalent replacements for well-known brands like CMR, Danfoss, Autronica etc. Regardless of whether they are standard or custom-made, our thermocouples are engineered for precision, durability, and long-lasting reliability across various industries.

We produce tailored chart recorders intended for industrial oversight and the long-term documentation of temperature, pressure, and various other process variables. Our recorders are constructed according to your specifications, offering choices for single or multi-pen formats, various chart sizes, and mounting configurations to meet the specific application requirements.

We also offer compatible charts and pens for our recorders but also for other chart recorder suppliers such as Cambridge, ITT Barton, Rototherm, Kent and many more. Get in touch to find out whether our charts support your chart recorder. 

We Manufacture durable dry block calibrators that can accommodate extensive temperature ranges and are customised to meet your specifications. These calibrators feature interchangeable insert blocks, digital controls, and outstanding thermal stability. Units can be designed to fit various sensor types and calibration ranges, providing rapid heat-up and cool-down, reliable performance, and long-lasting dependability.

Our dry block calibrators are perfect for both field and workshop applications, ensuring that sensing equipment stays accurate and compliant. They can also be tailored to customer specifications to meet a variety of industrial requirements.

Custom-made cables, wiring harnesses, and looms designed to meet your specific needs for industrial instrumentation and control systems. Our assemblies are constructed according to specifications and can include a variety of connectors, terminations, and protective sleeving to accommodate different applications.

Key features consist of:

• Tailored lengths and configurations to fit installation requirements
• Multi-core, screened, and specialized instrumentation cables
• Custom harness assemblies and cable looms
• Durable terminations and protective sleeving engineered for reliable operation in challenging environments

Our cable and harness solutions are designed for longevity and compatibility with sensor, recorder, and control equipment, ensuring reliable connectivity in critical situations.

Our interconnection rails are designed to provide reliable, high-performance electrical connectivity in demanding industrial applications. Engineered for strength, precision, and long-term durability, these rails form a critical link within complex power and control systems.

Built to perform under extreme conditions, our rails have been proven in some of the most challenging environments in the industry. Notably, HEI engineered and supplied interconnection rails for the MAN RK280 engine — the world’s most powerful 1,000 rpm engine — where uncompromising reliability and performance were essential.

With a focus on quality materials, precise manufacturing, and application-specific design, our rails deliver dependable interconnection solutions for high-power and mission-critical systems.
