Bluelab Truncheon Nutrient Meter - Standard Model | EC CF PPM | Waterproof
Regular price $147.99 Save $-147.99
The best selling hydroponics EC Meter in the world. Growers prefer the Bluelab Truncheon because it's easy to use, easy to read, extremely accurate and best of all it's reliable.
Use it to quickly and accurately test the conductivity levels (EC, CF & PPM) of your nutrient solution.
Features:
- EC, CF and PPM scales
- Fully waterproof
- Factory calibrated
- Auto turn on and off
- Battery life minimum of one year (or shelf life of battery)
- No external switches or adjustment knobs
- EC (0.2 - 3.6), CF (2 - 36) and ppm scales (TDS and 700 scale)
- Uses 3 x AA alkaline batteries (included)
Â
Testing is simple;
Dip the end of the Truncheon into the nutrient solution and wait for a minute or two for the Truncheon's probe to reach the same temperature as the nutrient.
- Remove the Truncheon from the solution, and then dip back in again to take the reading.
- The flashing lights along the side represent the value of the solution.
- It doesn't get any easier.
- Don't forget to rinse under fresh water after use, and clean once a week.
Â
Handy Hint: 95% of all Truncheons returned as 'Faulty' only require cleaning or new batteries. It's a great idea to buy a cleaning kit which contains everything you need, and check out the cleaning guide to keep your Truncheon in tip top condition.
Bluelab Digital EC Pen - Portable | Reliable | Temperature | PPM TDS EC
Regular price $125.00 Save $-125.00
The ultimate handy solution for measuring conductivity (EC or ppm) and temperature!
The Bluelab EC or ppm Pen simply tells you that your plants have the right amount of nutrient in your solution and lets you know if adjustments are needed. To feed plants well, we need to know what we're feeding them. Start with a quality nutrient.
Measuring the conductivity every day is the best way to avoid over-diluting or over-concentrating your nutrient solution. Completely change the reservoir solution every 7 days. Top up the nutrient level between changes - so your plants always have the right amount of food.
The Bluelab EC or ppm Pen also measures the temperature of the solution, as root health is vital to the success of a crop. Temperature affects the growth rate and structure of a plant so a solution temperature of 18 - 22 C or 65 - 72 F is recommended.
To make sure the plants can get at the food, you need to measure the pH of the solution. Check out our handy Bluelab pH Pen so you have every tool required to manage your nutrient solution.
Now isn't that Handy!

Bluelab Combo Meter - EC TDS | Conductivity | PH | Temperature | Battery Powered
Regular price $390.00 Save $-390.00
Bluelab Combo Meter
Itâs all you need for simple and reliable crop management.
The Bluelab Combo Meter is a portable pH, conductivity and temperature meter all in one. If you are experiencing problems with yellow leaves, or slow stunted growth, the Bluelab Combo Meter will soon tell you if each parameter is within the plants requirements. Adjustments can be quickly made to get your crop back on track.
The Bluelab Combo Meter has two probes, a Bluelab pH Probe and a Bluelab Conductivity/Temperature Probe. When taking a reading, simply place them into the solution and the selected reading is displayed on screen. As the Bluelab Combo Meter is portable and does not require a power supply to operate, it can be used anywhere, anytime to help you manage your cropsâ daily nutrient requirements.
Calibration of the pH probe is simple as instructions are supplied on the back of the meter and the easy push button method makes this one of the simplest meters to use.
The pH probe is replaceable so you can use this meter for years to come. The Conductivity/temperature probe does not require calibration as this is locked in during manufacture.
Often referred to as âThe Apple of Metersâ!

Ibebot SoilQuality Sensor - Soil Moisture & Nutrient Sensor | Cloud Based
Regular price $160.00 Save $-160.00
Moisture & Nutrient Sensor
- The SoilQuality sensor is a remote sensor which connects to your phone or smart device by Bluetooth and provides real-time data of your growing media (coco, rockwool & soil).
EC Measurement Â
- Soil Quality measures the Electrical Conductivity (EC) of soil and growing media.
- At a given temperature, the EC of any growing media is relative to the amount of nutrients - an increase in nutrient produces an increase in Soil Electrical Conductivity. Temperature is a factor that which affects the EC level. The higher the temperature the higher the EC. Most EC agricultural standards are given at 25°C.  As a rule of thumb, the EC of water increases by 2 to 3% for each increase of 1°C.
- To capture nutrients in the growing media, a plant needs water so minerals can be dissolved in water and be available as nutrients to the plant. In a dry growing medium a plant will not be able to grow and capture any nutrients. EC is also affected by the soil moisture: when the soil is dry, the EC greatly drops even if thereâs minerals available.
- Comparison of Nutrient level in time or between different samples should be done based on the same moisture level and temperature.
Measuring Moisture Â
- The 'SoilQuality' moisture measurement is given in Absolute Volume Ratio (AVR), which is the ratio between the volume of water divided by total volume of Soil + Water after mixing both.
- At 70% AVR moisture the soil becomes extremely close to a liquid and not adequate for growing. SoilQuality provides a AVR Soil Moisture measurement between 0 to 70% (anything above 70% will still show as 70%).
- âSoil Sensing Probeâ should be gently cleaned with disinfectant alcohol if moisture reading doesnât reach 70% in water.
EC Measurement in water or buffer solution Â
Although SoilQuality has been designed to measure EC of moist soil, it can also measure the hydroponics nutrient solutions, however the following precautions should be followed:
- Protective cap should be removed.
- During measurement, the moisture level will be saturated at 70% - this is normal.
- The âSoil Sensing Probeâ should be fully immersed into the solution - half immersed Sensor Probe will result in a half reading.
- The measured EC value should be compared with a reference EC value of a buffer solution given at the same temperature as the sampled liquid. Unlike most sensors in the Holland Forge range, this unit does not have ATC ( automatic temperature compensation).
- The âSoil Sensing Probeâ should be gently cleaned with disinfectant alcohol if EC reading doesnât match with expected value
- Data logging, Cloud Connected & Alerts
- Soil Moisture & Soil NutrientÂ
- Capture your plant's activity from pot into App.
- Sensoring the perfect nutrient balance blend for plant's soil quality.
- Optimum harvest with controlled light exposure.
