World's highest precision performance in resistance thermometer measurements. High precision: 20 ppb, high resolution: 1 ppb specifications.
The CTR9000 offers the highest performance in the measurement of resistance thermometers in the world. By leveraging the unique advantages of AC bridge technology, it enables reproducible measurements with the highest accuracy. Operating frequencies of 25/30Hz or 75/90Hz provide high resistance to thermoelectric errors and power frequency noise sources, achieving fast and continuous measurements. AC bridge technology is always superior to measurements using low-speed current reversal DC techniques, and this advantage is inherent in the fundamentals of electrical measurement. <Product Specifications> - Accuracy: < ±20ppb (±5 μK 1)), with an option for < ±0.1 ppm (±25 μK 1)) - Resolution: 1 ppb (0.25 μK 1)), with an option for 0.1 ppm (25 μK 1)) - Fast measurement time (2 seconds balance) - Differential and absolute measurement - Warm-up time < 30 seconds 1) The SPRT at 25Ω is based on a reference resistor of 25Ω. For more details, please refer to the product data sheet.
