  • Link4 offers versatile stainless steel temperature probes specially designed to work with your iGrow 1000 series controllers and the iDoser. Whether you’re measuring bottom heat, a mixing valve system, soil temperature, or any other zone, these durable probes will do the job. The iGrow 1000 Series Controllers can use up to 5 temperature probes in addition to indoor and outdoor temperature sensors. These rugged sensors are small and can be placed almost anywhere you need them in your greenhouse.
  • When you’ve got an entire grow operation going, you can’t be watching everything at once. But you can have a sensor that can. The ADISM sensor gives you complete peace of mind with a differential pressure to provide accurate readings for temperature, humidity, CO2, and solar light. Its intuitive programming makes it easy to set up and use on a day-to-day basis. It’s compatible with Link4’s iGrow 1800 and iDoser. Features:
    • Quick disconnect & junction box
    • VDP is available when combined with the Link4’s temperature probe
    • Temperature sensor
    • Humidity sensor
    • CO2 sensor
    • Solar light sensor
  • Anemometer

    Protect your greenhouse plants and ventilation systems from damage with Link4’s Anemometer. Constructed of rugged materials, this wind speed and wind direction system is strong enough to withstand hurricane-force winds, yet sensitive enough to detect the lightest breeze. Hand-balanced for optimal stability and accuracy, this precision instrument is sealed with stainless steel ball bearings for a long life.   Features:
    • Highly balanced sealed, stainless steel ball bearings for optimal stability and accuracy
    • Constructed with UV resistant materials for years of trouble free operation
    • Precision design for consistent and accurate readings
    • Wind Speed Range 3 to 175mph (4 to 282 kph)
    • Wind Speed Accuracy +/- 5%
    • Wind Direction Precision +/- 2%
    • Dimensions 21”x10”x5.5”
    • Weight 1.2lbs
    Notes this sensor is designed to mount to a 1 - 1 ¼” diameter galvanized pole, or 4”x4” wooden post (not included)
  • The Digital Integrated Sensor Module (DISM) sensor provides sensing for CO2, temperature, humidity and light to get the most out of your greenhouse operation. Comes standard with iPonic Series and includes 100 feet of cable.
  • Extension cable for the Digital Integrated Sensor Module available in 50 ft. segments.
  • EC Sensor, Graphite, 12mm, TC=10k NTC, K=1.0, TL (EC Black with Temperature sensor) In any hydroponic grow system, the health of your solution determines the health of your plants. But it’s not enough to just guess about it. Link4’s electrical conductivity sensor monitors your solution’s electrical conductivity, so you always know if there’s a change or a potential problem. It works with your existing Link4 iDoser, so you don’t have to worry about compatibility. It also has a convenient and portable design with smart sensors that simplify calibration. With a reliable performance and a one year limited warranty, you really can’t afford not to have the EC Sensor as part of your grow operation.
  • The iDrive series of motor controllers are perhaps the most compact, powerful, and versatile line of motor controllers on the market today. Packed with smart features such as a 5 position manual override switch, motor reverse delay, and high quality components, the iDrive series of motor controllers are capable of controlling nearly every type of vent and curtain motor out there.
  • A DC motor controller for 24Volt DC greenhouse motors With the increased usage of inexpensive DC motors for greenhouse applications, Link4 has designed a motor controller to address this specific need. Derived from the robust, reliable iDrive 300™, the iDrive 150DCP™ inherits all the similar high quality components and designs. In addition, it has advance capabilities to meet the specific needs of using a DC motor. Some of which are variable voltage adjustments for line losses, IR compensation, torque controls, etc. Don’t just use a 24V DC power supply for your motor!
  • A full-featured motor controller with built-in thermal overloads to protect your greenhouse motors The iDrive 300 Motor Controller is perhaps the most compact, powerful, and versatile motor controller on the market today. Packed with smart features such as a 5 position manual override switch, motor reverse delay, and high quality components, the iDrive 300 is capable of controlling nearly every type of vent and curtain motor out there.
  • This innovative digital sensor integrates temperature and humidity into one single chip sensor with CMOSens® Technology for superior quality. Housed within a protective shield that safeguards against radiation and reflected heat, the Digital Temperature & Humidity Sensor offers high precision for relative humidity and temperature readings. This unique design has no moving parts (which often get damaged), keeps power consumption low, gives fast response times of less than 4 seconds, and reports accurate readings at an affordable price.
  • When it comes to your grow process, the water quality can make or break the entire system. Link4’s pH sensor helps you accurately keep track of your pH levels, constantly analyzing for changes that could affect your yield. Plus, it easily interfaces with your existing Link4 iDoser for simplicity of use. Choose from regular and flat tip probes, depending on what best suits your operation. The durable body is guaranteed to last for up to a year with a low maintenance sealed gel design to prevent contamination.
  • If you want to know exactly how much light each of your plants are getting, look no further than the PAR light sensor from Link4. Calibrated for sunlight, this self-powered sensor measures PPFD (Photosynthetic Photon Flux Density) in your greenhouse grow. Its quantum sensors can also measure PARs (Photosynthetically Active Radiation) in your aquaponics setup. Its rugged and self-cleaning design makes it a reliable and long-lasting addition to your grow setup. You’ll never again have to wonder if your plants are getting the amount of light they need.
