Hanna HI981413 EC Controller · Automated Nutrient Doser for Hydroponics

The Hanna HI981413 EC Controller is a professional-grade automated nutrient dosing system with a built-in pump, designed to maintain the exact electrical conductivity your plants need to thrive.

Are you tired of playing mad scientist every day, manually measuring and adjusting the nutrient levels in your reservoir?

Hand-mixing nutrients is not only a massive time sink, but it also leaves room for human error. A slight miscalculation or a sudden drop in EC can stress your plants, causing nutrient deficiencies, stunted growth, or even devastating root burn that ruins your entire harvest.

With this automated controller, you can put your feeding schedule on autopilot. It continuously monitors your water and precisely injects the exact amount of nutrients required, ensuring your crop stays in the perfect sweet spot for explosive, uninterrupted growth.

Perfect Nutrient Balance for Maximum Yields

When you run Hydroponic and Aeroponic Systems, stability is everything. This device takes the guesswork out of your daily routine. Instead of checking your tank multiple times a day, you can trust the Hanna HI981413 to do the heavy lifting. It reads the EC or TDS in real-time and triggers the built-in peristaltic pump to dose your reservoir exactly when needed. This means faster vegetative growth, heavier blooms, and a lot more free time for you to just chill and enjoy the process.

How to set up and use your automated doser

Setting up this controller is straightforward, even if you're not a tech wizard. Follow these simple steps to get your automated feeding system running:

1. Installation: Mount the controller and insert the 1/2" NPT industrial probe into your recirculation line or directly into your reservoir.
2. Calibration: Use the included standard calibration solution (1.41 or 5.00 mS/cm) to automatically calibrate the probe for pinpoint accuracy.
3. Set your targets: Program your desired EC or TDS setpoint based on your plant's current growth stage.
4. Connect the feed: Hook up the dosing pump to your favorite liquid Cannabis fertilizers.
5. Automate: Turn it on and let the system automatically monitor and dose your reservoir, keeping your levels perfectly balanced.

Key advantages and benefits of the Hanna HI981413

• Built-in dosing pump (0.5 to 3.5 L/h): Automatically injects nutrients into your tank, which means you eliminate manual feeding and save hours of labor every week.
• Automatic temperature compensation: Adjusts readings based on water temperature, ensuring your EC measurements are always dead-on, giving you total peace of mind.
• Adjustable delay timer (0-600 sec): Prevents the pump from over-dosing when the system restarts, which protects your sensitive roots from sudden nutrient spikes.
• Industrial-grade probe: Built to withstand continuous submersion and harsh environments, providing you with long-lasting, professional-level reliability.
• Visual alarms and intuitive interface: Instantly alerts you if levels go out of range, allowing you to react quickly before your plants suffer any stress.

Maintenance and calibration tips

To keep your controller running like a dream, regular maintenance is key. Clean the probe monthly to remove any salt buildup that could skew your readings. Always keep a fresh stash of calibration fluid on hand and recalibrate the unit every few weeks to ensure maximum precision. If you're upgrading your grow room, pairing this unit with other high-quality measuring instruments will give you absolute control over your indoor environment.

Frequently Asked Questions

Can I use this controller for any type of liquid fertilizer?

Yes, the built-in pump is compatible with almost all liquid nutrients, making it highly versatile for any feeding schedule or brand you prefer.

Does it measure pH as well?

No, the HI981413 is specifically designed for EC (Electrical Conductivity), TDS, and temperature. For pH control, you would need a dedicated pH doser.

What is the maximum pressure the dosing pump can handle?

The pump has a maximum output pressure of 1 atm (14 psi), which is perfect for standard hydroponic and greenhouse setups.

Personal Experience of Pevgrow’s CEO (Alan)

When I finally decided to fully automate my hydroponic setup, the Hanna HI981413 was an absolute game-changer. Before this, I was constantly stressing over EC fluctuations, especially during the peak flowering stage when the plants are drinking heavily. Setting this unit up took me less than an hour, and the interface is incredibly intuitive. The best part? The peace of mind. I can leave for the weekend knowing my reservoir is perfectly balanced. The only minor drawback is that you need a separate unit if you want to automate pH, but for EC management, this is hands-down one of the most reliable pieces of gear in my grow room.
