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"). Variant (including works certificate) Sensor 2 m/s, length = 210 mm, with handle Order No. FVA935TH4 Sensor 2 m/s, length = 80 mm, with electronicbox Order No. FVA935TH4K1 Sensor 2 m/s, length = 300 mm, with electronicbox Order No. FVA935TH4K2 Sensor 20 m/s, length = 210 mm, with handle Order No. FVA935TH5 Sensor 20 m/s, length = 80 mm, with electronicbox Order No. FVA935TH5K1 Sensor 20 m/s, length = 300 mm, with electronicbox Order No. FVA935TH5K2 Typ FV A935-TH4Kx / -TH5Kx
