Thermo-anemometer probes FVA935TH4 and FVA935TH5 are especially suitable for measuring and recording flow velocity and temperature data even when measuring operations are performed in cramped and restricted conditions. .. Measured values can be acquired with a high level of accuracy even at velocities below 0.5 m/s (100 ft/min). .. The sensor can be used with either side facing the direction of flow. .. Temperature is compensated over a wide range. 0 to +50 °C. .. The sensor tube is only 6 mm in diameter (0.24").
