Martindale AV90 Anemometer with External Probe

The AV90 Anemometer with External Probe from Martindale can display temperature in C or F and can also show airflow at the same time.

The maximum and minimum figures for flow and temperature can be shown for further accuracy of measurement. Up to eight readings can be taken and average automatically.

Measurements can be taken over two or sixteen seconds with the average of two or sixteen being displayed.

The airflow measurement can be shown in metres/second, feet/minute, knots, mph or kph.
