Soil-quality measurements are achieved via the meter’s 7.9 in.-long, sensor-tipped probe and displayed on a 1.8 in. (46mm) backlit LCD. The DSMM600’s pH level measurement feature enables users to determine whether the acidity of the soil is suitable for particular plants. The pH measurement range is 3.5 to 9.0. The temperature, moisture and sunlight intensity measurement features help to pinpoint bad spots in gardens and lawns by identifying such issues as poor drainage, and inadequate or excessive wetness and sunlight. These parameters also impact ongoing indoor and outdoor plant maintenance and care. The instrument’s temperature measurement range is 16° to 122°F (-9° to 50°C), and readings can be displayed in Fahrenheit or Celsius via the °F/°C switch. Moisture content is measured within five levels, ranging from less than 5% (Dry+) to more than 30% (Wet+). Sunlight intensity is measured within nine levels, ranging from less than 500 Lux to more than 120,000 Lux.
