The new Surrey Sensors Ltd. Micro-CTA unit is now available! Possibly the smallest constant-temperature anemometry system available, this new, fully self-contained system is compact enough to fit inside a probe sting. Integrated temperature sensors enable direct calibration temperature correction- and with direct-to-USB data streaming and our robust silicon-film probe element, the micro-CTA system is ideal for use in noisy, dirty or corrosive environments.
