VitalInk EssentialsLab Ec Meter Calibration Solution 250ml

Essentials LAB EC Meter Calibration Solution is intended for use in calibrating EC meters to CF 28 – EC 2.80 – PPM 1820. Regular calibration will keep your EC Meter reading accurately.  Key selling points:   Highly accurate calibration solution   Ensures that your EC Meter is reading correctly   Technical Specifications:    Potassium Chloride solution    Electrical Conductivity: 2.8ms/cm @20°C  PH 4 - 5  Volume: 250ml   FAQs:  Q: When should I calibrate my EC meter, and why do I need to do it? A: The performance of an EC meter will change with time due to ageing. To ensure it is working correctly, regular calibration is a must. If you are using your EC meter daily, you should calibrate it at least once a week. Q: How should I use Essentials LAB EC Meter Calibration Solution to calibrate my pH meter? A: Ensure that your EC meter and the calibration solution are at similar temperatures, by keeping them in the same place for a while. Shake the bottle before use. Always pour a small amount into another container to test EC, and do not place your EC probe directly into the bottle. This will avoid contamination of the calibration solution in the bottle and will maintain its accuracy. After use, discard the solution used for calibration, and never put it back into the bottle. Follow the calibration instructions provided with your EC Meter.  Q: How should I store LAB EC Meter Calibration Solution? A: Always keep the bottle upright with the cap screwed tight to avoid evaporation or spillage. Store your calibration solution at temperatures between 5°C and 25°C, and out of direct sunlight. 

BlueLab PH Probe Storage Solution 100ml

Our Bluelab pH Probe KCl Storage Solution is a storage solution designed specifically for use with Bluelab pH Pens or pH Probes. Storage solution is used to ensure a pH probe is kept in ideal conditions during storage, while the probe is not in use. Typically, most storage solutions for pH probes contain a mixture of potassium chloride (KCl) and water. Some brands may contain small amounts of other ingredients. For this reason, we try to suggest using Bluelab pH Probe KCl Storage Solutions with all pH probes to avoid contamination from these other ingredients.

BLUELAB PH 7.0 Calibration solution 500ml

Keeping your pH meter calibrated is essential for taking accurate readings and keeping your nutrient solution within the correct pH range. Bluelab's pH Calibration Solution allows you to accurately calibrate your pH meter.

Growth Technology PH Buffer 4+7

Growth Technology PH buffer 4 and 7 solutions are of a known and fixed PH, which are used to calibrate your PH meter and should be done on a regular basis to ensure ongoing accuracy from the meter. Pour out a small amount to use for calibration and remember to discard the used solution when finished, do not pour it back into the container as it will contaminate your new solution. First use PH buffer 7 solution to calibrate your meter to neutral, once this is done we recommend you then use PH buffer 4 to calibrate your meter to this level, this will give you a two point calibration and be far more reliable than just calibrating to one
