Bluelab Truncheon
The Bluelab Truncheon is the world’s most trusted and widely used EC (Electrical Conductivity) meter, relied upon by commercial growers, hobby gardeners, nurseries, and hydroponic professionals across the globe. Designed and manufactured by Bluelab in New Zealand, the Truncheon has earned a reputation for exceptional durability, reliability, and simplicity, making it one of the most important tools any grower can own.
The purpose of the Bluelab Truncheon is to measure the concentration of dissolved nutrient salts in your water or nutrient solution. It displays readings in EC, CF, PPM500 and PPM700, allowing growers to accurately monitor nutrient strength and ensure plants receive the correct amount of fertiliser throughout every stage of growth.
Without monitoring your EC and pH, you’re effectively growing blind. Nutrient solutions that are too weak can slow plant growth and reduce yields, while nutrient concentrations that are too strong can lead to nutrient burn and plant stress. The Bluelab Truncheon makes checking nutrient strength quick, simple, and highly accurate.
Unlike many electronic meters, the Bluelab Truncheon never requires calibration, eliminating one of the biggest maintenance headaches for growers. Simply switch it on by placing the probe into your nutrient solution, and the bright blue LED display instantly shows the reading. There are no buttons, switches, or complicated menus to navigate.
Built to withstand demanding growing environments, the Truncheon is fully waterproof, making it suitable for everyday use in hydroponic systems, reservoirs, nutrient tanks, and commercial growing facilities. Its rugged construction and long battery life have made it the preferred conductivity meter for professional growers worldwide.
For over 30 years, Bluelab has been engineering precision water measurement equipment trusted by growers in more than 100 countries. The Bluelab Truncheon continues to be regarded as one of the most dependable conductivity meters available today.
