      Blue Labs soil Ph pen...

      This is nothing short of a real scientific tool...Having said that it important to read the booklet on how to care, how to use instructions and how to obtain a proper soil pH measurement. Accurate everytime when properly calibrated. A check mark ✅ appears on the LCD display telling you you are properly calibrated. So it takes the guess out of its accuracy.
      I wish it came with a hard case designed to store the Blue Lab Soil pH pen. If anyone knows of such item please let me know.
      I not sure how long this item was in stock but it needed to have water added to the KCl( potassium chloride) which probe sits in to keep wet at all times. The bulb nearly was dry...As the company saying goes..'if the bulb dries it dies' . So make sure as soon as you get Blue Labs soil pH pen that make please make sure when you order you soil pen that you also order kCl storage solution and ph7 and ph4 buffers to calibrate the pen and store it after use. They are not included in your order of the pen.
      Would recommend to anyone in need of soil data to better understand your dynamics soil condition. Oh does wet soil sample to and give detailed instructions on how to keep the samples accurate and consistent So guys read online material as well as booklets that come with the pen. Save yourself the greef... and learn from my mistake and spend the $40 more dollars for storage solutions and calibration liquids and get using your pen 1-24h after you get it in mail depending on the bulb/pen needing care.
