Combi Meter pH, EC and temperature measurement The Bluelab Combo Meter is a portable all in one pH, conductivity and temperature meter. 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 battery operated, it can be used anywhere, anytime to help you manage your crops’ 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. Measures pH, conductivity / nutrient (EC, CF, ppm 500 and ppm 700) and temperature (°C, °F) Lightweight and portable ∙ Large easy to read display ∙ Simple push button pH calibration.

Three-in-one portable solution

The fundamental parameters of pH, conductivity and temperature all play a pivotal role in driving optimal nutrient uptake. With the Bluelab Combo Meter with Leap pH Probe, you can measure all these fundamentals in one convenient, portable device.

While conductivity indicates the total amount of nutrients in your solution, pH (potential Hydrogen) shows how acidic or alkaline your medium is, which determines nutrient absorption. Temperature affects your plants’ growth rate and structure.

The Bluelab Combo Meter with Leap pH Probe measures pH, conductivity and temperature in substrates, nutrient reservoirs, run-off and water supply. What’s more, this meter can be used on the go, giving you fast and accurate readings when and where you need them.

Conductivity Pen pH and temperature measurement 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.

Multimeter pH Meter pH measurement Plants all need a particular pH to maximize the uptake of nutrient solution. Without taking control of the pH, plants can’t take up the necessary elements they need for good strong growth. The Bluelab pH Meter is the perfect, portable way to accurately measure the pH value of a solution so you can add the right amount of pH up or down to get growth back on track. Simply place the pH probe into the solution and the selected reading is displayed on screen. As the meter is hand held and does not require a power supply to operate, it can be used anywhere, anytime. 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 pH Meters in its class to use. The pH probe can be purchased as a replacement so you can keep on using the Bluelab pH Meter for years to come.

pH Pen pH measurement Plants get their nutrients 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.
