About Bluelab company

Bluelab was founded in 2000 in New Zealand when CEO Greg Jarvis purchased the grower suppliers company NZ Hydroponics, which was selling just one electronic product. Since then, Bluelab won the award for Excellence in Innovation at the NZ International Business Awards and grew its revenue every year. Nowadays, the company manufactures various measurement tools and control systems for controlled environment agricultural growers.

As mentioned before, this handy tool will help you to measure pH, conductivity, and temperature in nutrient reservoirs, run-off, or water supplies. It can be used on the go when you need fast and accurate readings. 

pH (potential Hydrogen) – shows how alkaline or acidic your prepared solution for the plants or your medium is. It’s crucial, as it determines nutrient absorption by the plants.

Conductivity – shows the total amount of nutrients in your prepared solution. With this Bluelab Combo Meter, you can customize conductivity in EC, CF, PPM 500 (TDS), or PPM 700.

Temperature function – shows the results in °C or °F. It affects plants’ growth rate and structure. 

After a couple of months of usage

The tool itself is very comfortable, feels high-quality in hand. The process of using it is straightforward, and the calibration process is very simple as well, so you can be sure that the results will always be accurate. You have to be aware that the pH probe is made out of glass, so any, even the slightest, damage can lead the pH probe to deliver false results. The Bluelab carry case is a good solution.
