The Model "LT" is the ultimate in sensitivity at the very "Wet" end of the soil water range(below 20 centibars of soil water suction)! It was designed to operate in very low water holding capacity soils (coarse sand) and non-soil planting mixes used in...
Top mounted meter. Uses AA or dry cell battery. The scientific way to water! Accurate instruments give you instant, accurate moisture readings. Meters can be calibrated to the soil type for reliable results.
A back saver! Foot step for better penetration in tough soils! Taper cut tip goes in easy and cuts a nice clean core, insuring complete sample removal. Core is approximately 14.25in.
You should calibrate EC meters every 1-4 weeks depending on frequency of use to verify their accuracy. To use, pour a small amount into a container and discard the remainder after each use.
The PHD is scientific and does not operate on batteries. Lasts for years when properly cared for. Accurate to within a +/- .2 pH in acidic soils. Use in slightly moistened soil to get readouts you can depend on.
