The fume cupboard probe (digital, wired) is a high-precision hot wire probe designed specifically for measuring air velocity, air temperature, and volume flow in laboratory fume cupboards, ensuring compliance with DIN EN 14175-3 and -4 standards. This specialized probe is essential for confirming the correct setup and safe operation of fume cupboards used in laboratories handling hazardous substances.

optimised for low air velocities (up to +5 m/s), the probe delivers fast and accurate readings, enabled by automatic absolute pressure compensation for reliable results under varying conditions. The probe connects to the compatible testo multifunction measuring instrument via a fixed cable (instrument sold separately), and features a clearly structured volume flow measurement menu for intuitive operation.

With timed and multi-point mean calculations, real-time data display, and built-in air density compensation, it offers both high performance and ease of use.

Testo's intelligent calibration concept ensures the probe can be recalibrated independently of the instrument, minimising downtime while maintaining exceptional accuracy.
