Bluelab Combo Meter


Bluelab Combo Meter

The Bluelab meters are now better than ever!

Conductivity units that can be measured with the Bluelab Combo Meter now include EC, CF, ppm 500 and ppm 700.
The LCD now displays the unit of the conductivity and temperature chosen, succesful pH calibration indicators, a low battery indicator and has blue text.

Better crops start with the Bluelab Combo Meter, it's all you need for simple and reliable crop management and it's all within arms reach. It is a conductivity, pH and temperature meter all in one. It comes with a pH probe and conductivity/temperature probe, which are simply placed 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 anytime and anywhere to help you manage your crops daily nutrient requirements. It is powered by 2 x AAA alkaline batteries.

Calibration of the pH is very easy, using the push buttons on the meter and fresh Bluelab calibration solutions. Conductivity and temperature do not need to be calibrated as this is locked in during manufacture.

The large 13mm(1/2") screen is an added bonus, displaying only the reading you are needing. "Everything you need, nothing you don't!" It will however tell you if the batteries are getting low and it turns itself off if you forget to save battery power. Selection of the required measurement is just a push of a button away!

The Combo Meter measures the conductivity, pH and temperature of a solution, so wherever these readings are required, the Bluelab Combo Meter is ready to go! Whether it is a reef tank, a swimming pool, a hydroponic nutrient tank or an industrial application, its easy to read screen, simple calibration process and low maintenance requirement will give you the reliable results you depend on.

The Bluelab Combo Meter gives you the added benefit of being able to select the display options for C or F and EC, CF or ppm 500.

Conductivity is the total soluble salts contained within a liquid solution. Because pure water does not conduct electricity it has a conductivity measurement of zero. By adding soluble elements to the water, electricity is able to move through the solution giving it a conductivity rating.

Conductivity is measured using various scales. The scales on the Combo will provide you with EC (Electrical Conductivity), CF (Conductivity Factor) and ppm 500 (parts per million) which is also known as TDS (Total Dissolved Solids).

pH is the measurement of acidity and its opposite, alkalinity in a solution. Neutral pH is 7.0 pH. Acidity measures below seven pH (7.0pH) with alkalinity measuring above it (7.0pH).

It is important to maintain a hydroponic nutrient solution at a pH level where the elements in the nutrient solution are consistently available to the plant. If the solution is too acidic or too alkaline it can cause "lock up" a situation which restricts certain elements essential for growth from being absorbed by the root structure.
