PR293 Series Microhm Nanovolt Thermometer
The PR293AS nanovolt micro-ohm meter is a high-sensitivity multimeter optimized for low-level measurements. It combines low-noise voltage measurements with resistance and temperature functions, setting a new standard in flexibility and low-level performance.
The PR291 series micro-ohm thermometers and PR293 series nanovolt micro-ohm thermometers are high-precision measuring instruments specifically designed for temperature metrology. They are suitable for numerous applications, such as measuring temperature data from temperature sensors or electrical data, testing temperature uniformity of calibration furnaces or baths, and multi-channel temperature signal acquisition and recording.
With a measurement resolution exceeding 7 1/2, compared to generic high-precision digital multimeters that have been widely used in temperature metrology for a long time, numerous optimized models are available in terms of range, functionality, accuracy, and ease of use to make the temperature calibration process more accurate, convenient, and faster.
Features
Measurement sensitivity of 10nV / 10µΩ
The innovative design of the ultra-low noise amplifier and low-ripple power supply module significantly reduces the reading noise of the signal circuit, thereby increasing the reading sensitivity to 10nV/10µΩ and effectively increasing the actual displayed digits during temperature measurement.
