Lightning warning system
• L75 model is upgradeable from a prediction system with Thor PC included for computer viewing to a full programmable system capable of controlling an number of the company’s horn systems
• Other L75 models include single horn-alert capabilities and equipment switching
• Optional software can distribute real-time data from 10 to more than 100 users
• Incorporates the latest circuitry and circuit board design in a small but reliable and affordable package
Thor Guard
Hobo soil monitoring station
• Multi-channel data logger measures and records soil moisture and temperature
• Used where data needs to be collected in multiple locations and then analyzed on a PC
• Based on smart sensor technology: sensors are recognized by the station without complicated wiring, programming or calibration requirements
• Compact size (3.5 inches wide, 4.5 inches high, 2.1 inches in diameter)
• Convenient data off-load options
Onset Computer Corp.
Strike Guard fiber-optic converter
• Converts standard RS-232 serial communications ports to bidirectional fiber-optic links
• Replaces copper serial data lines with fiber-optic cable
• Provides enhanced reliability over twisted-pair, short haul modems
• Instant termination – no connectors, crimping, polishing or epoxy
• Complete autonomy from external power supplies
Wxline
Turf Watch weather system
• Measures rainfall and calculates the evapotranspiration rate
• Allows user to compute the net difference between rainfall and irrigation applied and amount of water lost to run-off
• Allows multiple calculations of evapotranspiration for varying mowing heights and types of grasses
• Allows user to set alarms for certain weather conditions
• Stores historical data and time of weather conditions
• Helps reduce water and chemical use
Weather Metrics
Rain Watch with central control software
• Version 4.0
• Helps superintendents maximize water management and conservation practices
• Can be installed with all Rain Bird central controls
• Uses rain cans to measure rain as it falls
• Can cancel or pause irrigation
• Determines the type of rain event the site experiences
• Safe for a hydraulic network
Rain Bird Corp.
Kelway pH and water moisture probe
• Provides reliable pH readings from 3.5 to 8.0 and water moisture from 0 to 100 percent
• Operates through natural electric charge generated from soil through the metal side plates on the probe
• Accurate to +/- 0.2 on pH and +/-10 percent on moisture
• Includes instructions and carry case
• Requires no chemicals, distilled water or outside power source
• Requires conditioning film to clean side plates
Gempler’s
Hydra Probe for soil measurement
• Provides information about soil-moisture content, salinity and temperature
• Helps to optimize watering and fertilization
• Permanently placed underground below the root zone
• Measures electrical response of soil types by two parameters: dielectric constant and conductivity
• Dielectric constant is most indicative of water content; conductivity is dependent on soil salinity.
• A thermistor determines soil temperature
Stevens Water Monitoring Systems
WatchDog 800 weather station
• Ideal where multiple sensor measurements are required for temperature, soil moisture or rainfall data
• Can be customized by choosing as many as eight plug-in sensors, including option for one rainfall sensor
• Features a built-in data logger that stores measurements until user transfers data to PC
• Measurement intervals of one, 10, 15, 30, 60 or 120 minutes
• User can add as many as four plug-in sensors
