These meters simultaneously measure and datalog several ventilation parameters using a single probe with multiple sensors. Great for cleanroom filtration airflow measurements — they automatically calculate volumetric flow rate for round, square, and rectangular areas. All models measure velocity, temperature and calculate flow.Model 10271-37 include addition functionality for measuring humidity and calculating dew point and wet bulb. Probe included with model 10271-37 that articulates up to 90°. Auto shut-off preserves battery life, and a low battery indicator alerts user of battery condition.

      These meters and probes are calibrated to NIST standards prior to leaving the factory. In order maintain NIST standards, it is recommended to have this calibrated on a regular (typically yearly) basis once you have received the product.
