The World’s favourite conductivity meter. Simply brilliant, brilliantly simple!

It is essential when growing with a hydroponic solution to KNOW what the strength of the solution is before feeding your plants AND while they are growing. If the conductivity reading is too low, your plants may not be getting enough nutrients. If the conductivity reading is too high, plants can dehydrate.

Understanding the conductivity of the nutrient solution takes the guesswork out of feeding plants. It will also save you money! Using the Bluelab Truncheon® Nutrient Meter is the fastest and easiest way to measure the conductivity!

To take a reading of your solution – simply place the probe head into the solution and the reading is indicated by the flashing lights. Calibration of the Truncheon® Nutrient Meter is not required.

Features

• • EC (0.2 – 3.6), CF (2 – 36) and ppm scales (TDS and 700 scale)
  • Fully waterproof
  • No calibration required
  • Auto sense on and off
  • No external switches or adjustable buttons
  • Battery life minimum 1 year (or shelf life of battery)
  • Meter Length 40.7cm
  • Guarantee: 5 year guarantee for Bluelab Truncheon® Nutrient Meter (proof of purchase is required)
    

It is important to check the EC of the truncheon using the Bluelab 2.77EC Conductivity Standard Solution (we do stock this for your convenience) at regular intervals and to clean it so that it is operating optimally. Check out the YouTube video below which explains how simple this is.

The ultimate handy solution for measuring pH and temperature!

Plants get their nutrient from minerals but they can only get all the right minerals they need if certain conditions are right. Think of nutrients like a lock. pH is the key. A key factor that affects food uptake is whether your solution is acid or alkaline. We measure this in pH.

The Bluelab pH 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.

The hand held pH pen provides a compact quick and handy way to manage the success of your crop to ensure maximum uptake of nutrients.

Teamed with our Bluelab ppm or EC Pen, you have a handy, convenient and accurate system for ensuring optimum plant growth and health.

Features

• Measures pH and temperature
• Selectable units for temperature
• Backlit LCD display
• Double junction probe (not replaceable)
• Successful pH calibration indicator
• Hold reading function
• Low battery indicator
• Fully waterproof
• Auto off function
• Automatic temperature compensation
• 1 x AAA alkaline battery included
• Guarantee: 1 year guarantee for Bluelab pH Pen, 6 month guarantee for Bluelab pH Probe (proof of purchase is required)

It is vital to use pH Storage Solution with this meter, to extend the pH probe’s lifespan.

A replacement probe for Bluelab Combo and pH Meters, and Guardian Monitors

The Bluelab pH Probe is a replacement pH probe (electrode) suitable for use with Bluelab products that test the pH value of a solution.

Unfortunately pH Probes do not last forever as they age through normal use and will eventually fail. With good care and use (keeping the probe tip wet and cleaning once a month) you will extend its life.

The Bluelab pH Probe has a double junction reference which provides a longer life than many other pH probes and is a gel filled non-refillable probe, so apart from cleaning is maintenance free.

Replace only the pH probe, not the whole meter

Probe cable length: 2 meters / 6.5 feet

WARNING: This product can expose you to chemicals including Di (2-ethylhexyl) phthalate (DEHP), which is known to cause cancer and birth defects or other reproductive harm.

FEATURES

• Double-junction probe reduces reference contamination, extending longevity  
• Fully waterproof - not just water resistant  
• BNC connector allows use with all other compatible Bluelab products  
• 2-metre cable for measuring in hard-to-reach locations 
• Use the included storage cap with KCl to lengthen probe’s lifespan 
• Fast sensor response ensures quick and accurate measurements  
• Polycarbonate housing for long-lasting strength  
• Effective in solutions of 0.2 EC and above 
• Six-month guarantee for the Bluelab pH Probe (proof of purchase is required).

Bluelab pH Probe maintenance

Extend the life of your pH probe

You need to regularly clean and maintain your Bluelab pH Probe to ensure its ongoing accuracy and longevity.

Use Bluelab’s Probe Care Kit, which contains everything you need to clean and care for your pH probe. Every time you clean your probe, calibrate it using Bluelab Calibration Solutions. 

In addition, boost your probe’s lifespan by ensuring that its tip stays wet at all times. Use the included storage cap whenever you’re not using your probe and regularly top up the amount of KCl inside the cap. 

This probe is compatible with all Bluelab products with a corresponding BNC connector, such as the Combo Meter and Guardian Monitor.

The simplest and most effective reservoir monitor you could ever own!

The Bluelab Guardian Monitor provides 24 hour continuous reading for pH, conductivity (EC/ppm 700/TDS/CF) and temperature within a nutrient solution.

Optimizing these critical parameters through a plants’ growing phase helps ensure a successful crop.

Designed for indoor use, the Guardian Monitor can be mounted on a wall or hung on a support bar. Set up your reservoir, place the pH and conductivity probes in the solution, then adjust and glance!

Simply set high and low alarm states – if the solution moves away from the ideal range, the display flashes. A quick look at the monitor will let you know when your nutrient solution needs adjusting.

The ultimate handy solution for measuring conductivity (EC or ppm) and temperature!

The Bluelab Conductivity 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 Conductivity 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.

Features

• • Measures conductivity and temperature
  • Selectable units for conductivity and temperature
  • Backlit LCD display
  • Calibration optional
  • Successful EC or ppm calibration indicator
  • Hold reading function
  • Low battery indicator
  • Fully waterproof
  • Auto off function
  • Automatic temperature compensation
  • 1 x AAA alkaline battery included
  • Guarantee: 1 year limited guarantee for Bluelab Conductivity Pen (proof of purchase is required)
    

It is important to check the EC of the conductivity pen using the Bluelab 2.77EC Conductivity Standard Solution (we do stock this for your convenience) at regular intervals and to clean it so that it is operating optimally. Check out the YouTube video below which explains how simple this is.
