Smart Temperature & EC Meter
You will receive a free EC meter with orders over US$250 from November 15 to December 15. The meter will be shipped after November 30.
Smart EC Meter for Hydroponics
- Real-Time Monitoring: Accurately track the EC (electrical conductivity) and temperature of your nutrient solution in your hydroponic reservoir.
- Instant Readings: View readings directly on the meter screen or through your phone.
- App Control: The app enables continuous reading, water shortage alerts, and optional oxygen pump control for enhanced oxygenation.
- Durable Probe: Designed for year-long immersion without oxidation, offering reliable readings anytime, including low-EC level alerts.
- Universal Compatibility: The probe is compatible with most hydroponic pods, transforming older non-smart hydroponic systems into smart systems.
- Optional Water Pump: Creates gentle water movement to increase oxygen levels for healthier roots and automatically cycles every 30 minutes to keep nutrients well-mixed.
- Extended Monitoring: Includes a backup probe, providing up to two years of continuous monitoring.
Will I Have a Better Harvest if I Use an EC Meter?
Yes, using an EC meter can improve your harvest. As plants absorb nutrients, the EC level in the water changes, so it’s important to adjust the nutrient solution to maintain optimal levels. Additionally, different plants require specific EC levels that universal nutrient solutions often cannot provide. By using an EC meter, you can monitor and adjust the nutrient concentration to perfectly suit each plant, leading to a healthier growth cycle and ultimately a better harvest.
Why do you need a EC Meter?
An EC meter is essential in hydroponics and similar systems because it measures the concentration of nutrients dissolved in the water, ensuring plants receive optimal levels for healthy growth. By monitoring and alerting to any changes, an EC meter helps prevent nutrient deficiencies or toxicity, improves plant health, and saves resources by minimizing nutrient waste. For growers, it allows real-time adjustments to nutrient and water quality, ensuring an efficient, well-balanced growing environment that’s crucial when growing without soil.
What are EC meter monitoring?
LetPot EC meter are monitoring two main value：
Nutrient Concentration: EC meters measure measures the concentration of soluble salts (like sodium, magnesium, and calcium ions), pH levels, essential nutrients (nitrogen, phosphorus, and potassium), trace elements (such as iron and zinc), organic matter, and moisture in soil or nutrient solutions. This helps farmers and gardeners monitor plant health, adjust nutrient levels, and maintain optimal growing conditions, reducing the risk of nutrient deficiencies or over-fertilization that can impact the environment.
Temperature: LetPot EC Meter can monitor the water temperature, which affects nutrient solubility and plant absorption.
You May Also Want to Ask
How Can I know the perfect EC Levels for differernt plants
You don’t need to guess the ideal EC levels for each plant. Simply select the plant type in the app, and the device will automatically alert you to when the EC level is higer or lower than the perfect ec range
Do I Need to Clean the Probes?
There is no need to clean the probes unless you plan to perform a calibration
Should I choose the pump version?
If you’re using a LetPot hydroponic system, there’s no need to purchase the pump version, as it already includes a pump for oxygenation and water circulation.
However, if you’re using a DIY hydroponic setup or a system from another brand without a built-in pump, you may want to choose our pump version.
What If I Use Universal Nutrient Proportions?
Using universal nutrient proportions will keep your plants healthy, but they may not reach their optimal growth and appearance. Specific nutrient ratios tailored to each plant type provide the best results.

The first universal EC meter for all hydroponics
Transform your old non-smart hydroponic system into a smart one
Enhanced Probe
Our probe is electroplated with three different metals, allowing it to remain submerged in the nutrient solution for up to one year without removal.
Extended Monitoring
LetPot provides an additional probe as a backup, enabling an extra year of monitoring once the original probe reaches the end of its lifespan.
Real-Time Readings
With the probe continuously submerged in the water reservoir, you can access real-time readings on the meter screen or through the app at any time.
Smart EC Alert
No need to determine the ideal EC level for each plant. Simply select the plant type, and the device will alert you automatically.
Universal Pod Compatibility
The probe is designed to fit seamlessly into the pod basket, making it compatible with most desktop hydroponic systems.
Clear Reading Panel
The meter features a color-coded indicator for easy readability: red for high levels, blue for low, and green for normal
How to connect LetPot EC Meter with your Hydropnic Device
Step 1
Connect the USB cable and Type-C power cable to the EC meter. The device will power on automatically.
step 2
Insert the probe into one of the pods in your hydroponic system. Then, press and hold the "EC" button for 3 seconds to activate the device. The meter will begin collecting data as soon as it is powered on.
Adding Oxygen Pump (optional)
If you have the pump version, connect the pump cable during Step 1. For easier cable organization, you can use the same pod where the probe is placed and carefully thread the pump cable through the pod.
