pH and Conductivity Measurements in Coconut Coir Substrate Coconut coir testing involves extracting a sample solution with distilled water and measuring the pH and conductivity of the extract. The acceptable conductivity ranges for 1:2 (v/v) dilution and pour thru sampling methods are 0.26-0.75 mS/cm Scan QR Code for link and 1.0-2.6 mS/ cm, respectively. The ideal pH range is 5.4-6.2 for both methods. Soil pH and Nutrient Availability The desirable soil pH range for optimum plant growth varies among crops. Generally, soil pH 6.0-7.5 is acceptable for most plants as most nutrients become available...

Measurement of Potassium in Soil Measurement of Calcium in Soil Calcium is one of the essential nutrients taken up by plants from soil for cell wall development. To measure calcium concentration in soil, extraction with 1M ammonium acetate and filtration Scan QR Code for link should be performed prior to placing the filtrate onto the flat sensor of LAQUAtwin calcium ion meter. Rapid In-Field Determination of Nitrogen in Onions Fresh root sap analysis with LAQUAtwin nitrate ion meter offers cost-effective, rapid, and easy solution to determine nitrogen status in onion plants. The nitratenitrogen...

Aquarium Water Testing Testing aquarium water such as freshwater and saltwater (either natural or artificial seawater) with reliable instruments is necessary to create a clean and safe environment for your aquatic species. The LAQUAtwin pocket Scan QR Code for link meters require only few drops of water and deliver the results in just few seconds. pH Measurement to Determine Acidification of Sushi Rice The rice used for sushi must be acidified with acetic acid (vinegar) to pH less than 4.6 to inhibit the growth of pathogenic bacteria. To measure pH, simply Scan QR Code for link place a sample...

Measurement of Calcium in Milk and Milk Beverages Determining the calcium content of milk and milk beverages helps consumers accurately gauge their calcium intake. Unlike atomic absorption spectroscopy (AAS) and inductively coupled plasma atomic emission spectroscopy (ICP), the LAQUAtwin calcium ion meter offers a Scan QR Code for link simpler method of measuring calcium ion-ionizing proteinbound calcium in sample using acid before analysis. pH of Cement for Floor Installation Testing Fresh concrete is usually very alkaline, above pH 11. When the alkalinity in a concrete subfloor is high, it...
