Feature: 1. Movable Panel: The maximum movable angle of the screen panel is 45 degrees, you can adjust the angle according to the demand, convenient to read the indicators. 2. Multi-Functional Design: Combining pH/EC/moisture/fertility/light test and temperature measurement functions. Multi-purpose machine, more energy-saving and environmental protection. 3. LCD Large Clearly Display: The screen clearly displays pH, EC, moisture, fertility, light and temperature at the same time. Let you understand the current soil condition more accurately and more faster, the data are readily available at a glance. 4. Portable and Durable Design: The 13mm diameter special thickened electrode is not only highly accurate, but also more durable and will not break easily, suitable for outdoor and various complex environments. 5. Wide Range of Applications: Can be used for potted planting, scientific experiment, orchard planting, grassland and pasture, agricultural planting, etc. Specification: Specifications: Model: YY-1088 Material: ABS pH Range: 0.00-14.00pH Resolution: 0.01pH Accuracy: 0.05pH EC Range: 0.01-10.00mS/cm Resolution: 0.01mS/cm Accuracy: 2%F.S Light 3 grid: weak 6 grid: moderate 9 grid: strong MOIST (1 grid=Water droplet) 2~3 grid: dry 4~5 grid: moderate 6~7 grid: moist 8~10 grid: Too humid Fertility Range: 0-99% Resolution: 1% Accuracy: 2%F.S TEMP Range: 0.0-80.0; 32.0F-176.0F Resolution: 0.1; 0.1F Accuracy: 0.5 pH Calibration pH: pH7.00/pH4.00/pH10.01 (Priority calibration of pH7.00 solutions) EC: 1413s/cm calibration solution Work Environment: 0-80C(32.0-176F ); RH 100% Display: LCD Backlight Display Battery: 4 * AAA Batteries (Not included) Automatic Shut-Off: 5 minutes Item Size: 278 * 65 * 30mm / 10.94 * 2.56 * 1.18in Package Weight: 334g / 11.78oz Package Size: 33 * 9 * 4.2cm / 12.99 * 3.54 * 1.65in Package List: Package List: 1 * Soil Tester 1 * 1413s/cm (1.413mS/cm) EC Standard Solution 1 * pH4.00 Powder 1 * pH7.00 Powder 1 * pH10.01 Powder 1 * Cleaning Cloth 1 * Cleaning Brush 1 * User Manual (English)
