Maximum MAC3 Wind Speed Alarm


  • Incorporating Maximum's renowned #400 anemometer, the MAC3 can be configured for simultaneous use with dual sensors to monitor two separate locations.

    The MAC3 integrates time delay and latching capabilities to prevent equipment damage due to frequent on/off power cycling, and has a large, easy-to-read green on black LCD panel for viewing wind speed conditions, settings and user-defined information such as wind speed averages, peak gusts and other key metrics.

    The instrument can be password protected to prevent unintended changes to settings, and the two optional 5 amp relays can provide on/off control for external devices such as outdoor venue equipment and agriculture devices, and an incredibly wide variety of other devices that can be affected or become unsafe in windy conditions.

    • Large, easy-to-read LCD display with green on black text
    • Display 'Current', 'Peak' or 'Average' (2-, 5- or 10-minute) wind speed conditions
    • Audible warning buzzer - external speaker and strobe also available
    • Optional dual sensor set-up to monitor wind speeds in 2 separate locations simultaneously - up to 1,000 ft between sensors
    • Dual set points (alarms) 0-255 mph for each sensor: Warning Level: yellow; Control Level: red
    • Two relay outputs to operate external devices are available as an option - one 5-Amp SPDT relay for each set point and each sensor
    • Integrated time delay and latching switch minimise risk of equipment damage due to power cycling
    • The MAC3 housing and the #400 anemometer are weather-tight to the IP65 standard and rated for use from -40 to 158 degrees F (-40 to 70 degrees C)
