Testing Instrument
Digital Soil Meter เครื่องวัดค่า PH แบบดิจิตอล
• Digital display soil pH meter with multi-functions measuring ground temperature, soil moisture, and illuminance
72716
• With backlight • Switch allows easy change between soil acidity (pH) and temperature (℃)
• Auto power off function
Acidity of soil, temperature of soil, moisture of soil, illuminance LOW–, LOW, LOW+, NOR–, NOR, NOR+, HGH–, HGH, HGH+ DRY+, DRY, NOR, WET, WET+ pH 3.5 - 9.0 (minimum pH 0.5, accuracy ±pH 0.5) – 9 - 50℃ (minimum 1℃, accuracy ±1℃) 1x 9 V battery (Battery included is for trial use only and may not last as long)
Measuring Target
* This unit cannot measure liquid acidity. * When measuring, please make sure soil has sufficient moisture as if a mud ball was to be made * Cannot accurately measure in confined environments such as a small bowl. * Cannot measure alkalinity.
Measuring Range Luminous Intensity (9 levels) Moisture of Soil (5 levels) Acidity of Soil (14 levels)

• Auto power off function • Compact, pocket-sized
EC means Electric Conductivity. If the EC value of soil is too high (above 1,500 μS/cm), crops cannot absorb nutrition effectively and it affects how they grow. ATC is an abbreviation for Automatic Temperature Compensation, which is a function that compensates for temperature changes in the liquid being measured by changing the measurement value. This allows precise measurement even without conversion. • Hold function (only for soil EC Measurement Mode) • Automatic Temperature Compensation (ATC) function • IPX5 rating means it can be used safely even if it gets wet * Waterproof: Protected from low pressure water jets from any direction.
When measuring soil conductivity, measure the top clear layer of the solution mixed with a ratio of 1 part soil to 5 parts water.
* Calibration with a standard solution (sold separately) is required before use. * If the value after calibration is not stable, replace the electrode part.
