You can follow developing storms or keep track of rapidly-changing weather conditions with this traditional 3-instrument weather station. Montauk is our most popular home weather station. It is an arrangement of wind speed and direction, temperature, and pressure instruments, on a 3-instrument mounting panel. -
When you want real time wind speed, direction and high wind gust measurements, Maestro is the answer. It gives you the ability to monitor the wind in a classic, elegant display. Wind speed is displayed in MPH and the km/h equivalent. Wind direction is displayed via eight red LEDs. Wind speed is self-powered by the rooftop wind speed sensor, while the direction LEDs are powered by the included AC adapter. The highest gust of wind is saved with our unique Gust Register, allowing you to monitor exactly how hard the wind blew even if you are not present when it occurs. https://youtu.be/a8PJbJskBaI?si=SsUYxIulRA78jA0h -
Modern technology meets old world charm in a sophisticated 3-instrument, digital display that allows you to track up to six local weather conditions. Blackwatch home weather station is an arrangement of Maximum instruments that measure wind speed and direction, atmospheric pressure, and rainfall amounts along with a 3-instrument mounting panel. -
Track the tide with Harbormaster, a precision east coast tide clock. It makes it easy to track the tide at your favorite coastal location, regardless of where you are. Powered by a single AA battery (included), Harbormaster tracks according to the average time between lunar high tides in the Atlantic Ocean (12 hrs, 25 min.). Fluctuations in conditions, location and the distance of the Moon from Earth can effect this average. However, over a lunar month, your Harbormaster tide clock will provide a practical indication of local tides. https://youtu.be/JHBqZoGEk_E -

Are you looking for a wind instrument that does it all in an easy-to-read digital display? Merlin gives you real time wind readings as well as peak and average wind speed and direction while also forecasting trending wind speed. Digital readings are given in four modes: 'Present' displays existing wind conditions; 'Peak' gives speed and direction of highest gust since last reset; 'Average' reveals average wind speed and direction since last reset; and 'Forecast' compares the most recent 12-minute average wind speed with the average for the previous 12 minutes. -
The MAC3 Wind Speed Alarm provides operators with a wealth of features and an unprecedented level of control. It is highly accurate, rugged and an ideal solution for managing commercial equipment by collecting and monitoring conditions and providing timely alerts to keep you abreast of wind speeds that could cause safety concerns for people and equipment in nearly endless applications. 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 5 amp relays can provide on/off control for external devices such as outdoor venue equipment, agriculture devices, municipal fountains, construction equipment and lifts, cranes, security systems, awnings and gate controllers, outdoor advertising and an incredibly wide variety of other devices that can be affected or become unsafe in windy conditions. The Maximum MAC3 controller and anemometer are weather-tight to the IP65 standard and rated for use from -40 to 158 degrees F (-40 to 70 degrees C). Operating in 12- and 24-Volt DC power source environments, the controller measures 5.08 inches wide x 7.39 inches high x 2.26 inches deep (129.0 mm x 187.8 mm x 57.4 mm). MAC3 is shipped complete with one (1) #400 wind speed sensor, 100' sensor cable, 14" straight, stainless steel stub-mast and mast mounting hardware. -
The DIC-3 hand held anemometer features Maximum's unique folding 3-cup design. Cups collapse for easy storage, and the instrument comes with a custom carrying case. To determine wind speed simply open the folded cups and hold the instrument in a wind current. Unlike fan type hand held anemometers that must be aimed precisely into the wind, our wind tunnel tested accuracy is not affected by its position. Wind direction is variable and this instrument records accurately from any direction. DIC-3 has four selectable scales: MPH, Knots, km/h or m/s, to be shown on the 2-digit LCD screen. A single 9V battery (included) powers the LCD for up to 70 hours of continuous use. DIC-3 provides readings up to 155 MPH in one of four modes: instantaneous velocity, highest gust since reset, 2-minute or 5-minute wind speed average. Cup rotor is 5.88" in diameter when extended. -
The BTC hand held anemometer features Maximum's unique folding 3-cup design. Cups collapse for easy storage, and the instrument comes with a custom carrying case. To determine wind speed simply open the folded cups and hold the instrument in a wind current. Unlike fan type hand held anemometers that must be aimed precisely into the wind, our wind tunnel tested accuracy is not affected by its position. Wind direction is variable and this instrument records accurately from any direction. BTC registers wind speeds from 0-35 MPH or 0-70 MPH (also scaled 0-30 Knots and 0-60 Knots) with its jeweled meter movement. User selects high or low range with a button. Cup rotor is 5.88" in diameter when extended. -
Includes a secondary component (track mounted curcuit board) that translates standard #400 anemometer output to industry standard 4-20mA. AC Voltage generating, polycarbonate, 3-Cup anemometer that is calibrated to a master to be interchangeable. Utilizing a single coil (approx. 2.02 VAC at 60 cycles), the #400 is a frequency counting sensor that is suitable for applications where voltage output is not important.

The Maximum Air Temperature Sensor weather instrument contains a precision thermistor that has been potted in a nickel-plated, brass probe. The brass probe measures 1/2" O.D. x 1.00" L, and protrudes through the bottom of a PVC cylinder that is 1.31" O.D. x 0.81" H. A secondary 2.25" O.D. white plastic disk provides shade over the probe to diminish the effect of direct sunlight on the thermistor. The precision thermistor is a solid state device which changes its resistance inversely proportional with temperature from 150,000 Ohms at the low end to 1,500 Ohms at the high end. Interchangeability of thermistors is /-0.2ºC; time constant 10 seconds. Ships complete with 60' of 22 AWG, 2-wire, UV protected cable.
