The IM159 is a precision-built handheld anemometer made from non-ferrous metal. Wind speed readings are shown on an analogue scale calibrated in knots, metres per second or miles per hour. We use a wind tunnel to calibrate the device and can issue a certificate of conformity.
The IM159 Handheld Anemometeris a mechanical instrument and requires no battery or form of electricity. It is manufactured to British Meteorological Office specifications (ref. 23510) and is ideally suited for use as a contingency device in case automated sensors become unavailable. Its primary application is on offshore helidecks (see CAP 437: Standards for Offshore Helicopter Landing Areas).
It is advised that the IM159 is serviced annually to ensure it continues to function optimally and provide accurate readings.
What are IM159 Anemometer
The IM159 Anemometer is a precision cup anemometer designed for dependable wind speed monitoring in meteorological, industrial, environmental, and research applications. Manufactured by Munro Instruments in the UK, this sensor provides stable long-term performance and accurate readings even in harsh outdoor conditions. It is widely used in weather stations, agricultural monitoring systems, construction sites, building management systems, and renewable energy projects.
