This new rugged digital pH Meter uses a stainless steel probe with an imbedded ISFET chip to measure pH directly in the soil up to a depth of 6 inches deep. Since you can test directly in the soil, there is no easier way to measure pH in the field. No mixing of slurries and since the probe contains no glass it is rugged and can be stored dry. The USB port is well protected by a tightly sealed cover and the casing and battery door are fitted with rubber seals. Powered by 3 rechargeable AA-batteries (AC adapter included) Modern User Interface.
