Precision Test & Measurement Instruments

Test instruments are often seen as just another component in a larger setup — a necessary tool, but rarely the centerpiece. However, much like a microscope in biology or a compass in navigation, a precision measurement instrument is fundamental. Without accurate measurements, even the most sophisticated systems and devices cannot be validated, characterized, or improved.

Design Concept

Keithley instruments are built on a design philosophy that emphasizes ultra-precision, reliability, and long-term stability. These solutions are engineered for users who demand the highest levels of performance and repeatability, often pushing the boundaries of what is physically measurable. Whether it’s ultra-low current sourcing or sub-nanovolt sensing, Keithley products consistently deliver results that exceed expectations in real-world environments. Continuous innovation, combined with deep customer engagement, ensures that Keithley remains at the forefront of measurement science.

Manufacturing with quality at its core

Keithley develops and manufactures its products with strict quality control and attention to detail. Every instrument is subjected to extensive testing and calibration before leaving the production facility, ensuring performance that customers can rely on for years.

By integrating precision analog and digital design, Keithley’s solutions minimize noise, maximize accuracy, and offer a superior user experience. This uncompromising focus on quality is supported by Tektronix’s global infrastructure and engineering resources, ensuring consistent excellence across all products.

Result

The result of Keithley’s commitment to engineering excellence is a portfolio of instruments that offer exceptional resolution, accuracy, and long-term stability — even in the most demanding environments. Keithley systems are designed to operate in electrically noisy conditions without compromising measurement integrity.

Thanks to this rigorous approach, Keithley customers benefit from high signal fidelity, low measurement uncertainty, and fast time-to-insight — all of which contribute to better decision-making, increased productivity, and lower total cost of ownership.

Service and support

At Keithley, creating high-performance instruments is only part of the mission. Equally important is the commitment to providing world-class service and support. Through CN Rood and a global network of technical experts, customers receive personalized guidance, training, and ongoing assistance — ensuring that their investment delivers maximum value over time.
