The Bluelab Calibration Solutions are a very necessary part of a growers toolbox. These solutions are manufactured specific to the calibration process and referenced to high laboratory standards by Bluelab. They are required for the calibration of pH meters, pH monitors and controllers. Regular cleaning and calibrating of pH measuring equipment ensures accurate readings. Bluelab's EC/CF equipment does not need calibrating, as they are all factory calibrated at Bluelab. The CF27.7 solution is used as a reference to ensure you have adequately cleaned the EC/CF probe.

Seasonal changes, sunlight hours, wind, inherent plant growth; from vegetative to fruiting; are all influencing factors to plant growth success. But more importantly, these parameters change the plants uptake and need of water and specific nutrient elements. The Bluelab Guardian is a constant indicator of the desired levels of EC, pH and temperature, enabling the grower to optimize these parameters as the crop progresses through each growing phase.

The Bluelab Guardian removes the complexity of how each parameter relies on each other for outstanding growth. Our innovative monitor is a new method to help guard the success of your crops with immediate and accurate results. A flashing display lets you know if one parameter moves away from the ideal, allowing you to make the required adjustments quickly and effectively.

The Probe on Bluelab meter, monitor, Truncheon or controller must be kept clean. If the probe is contaminated or dirty, it affects the accuracy. The probe surface is where the instrument takes the reading of the solution and the information is sent back from the probe to the electronic brain of the instrument. Cleaning is a very easy task and it prolongs the life of the truncheon.

Easy to clean because of its bullet shaped glass bulb. Fully waterproof and less fragile than all-glass electrodes because of its tough polypropylene barrel. Gel filled (non-refillable) making it maintenance free and a double junction reference providing longer life!

A portable, easy to use Soil pH meter that asssits in maintaining optimum soil condition for improved plant development.

Bluelab soil pH Pen - get your hands on Bluelab's newest hand held meter.

This clever Soil pH Pen will help you manage the success of soil grown crops. The Soil pH Pen provides a pH and temperature reading of soils and media, so you know the right nutrients will be made available to your plants. It will measure solutions also...

Soil acidity and alkalinity are common fertility problems that can cause stunted growth and abnormally coloured leaves. If you are having trouble determining the reasons for poor growth or plant health, testing the pH of the soil/media is a great place to start.

Low soil pH causes aluminium ands manganese toxicity in plants and reduces the availability of soil phosphorus. High soil pH also reduces soil phosphorus availability and reduces micronutrients such as zinc and boron to plants.

This high quality pH probe is designed specifically for measuring the pH of soils.

It can easily be fitted to the Bluelab pH Meter or Bluelab Combo Meter.

Contact Rings are replaced on the pH Truncheon every six months to avoid contamination of the actual probe cell. They come in a sealed foil pack of three to keep them moist.
