GroLine Portable pH/EC/TDS/℃ Meter HI9814D 1 unit

This is a pH/EC/TDS/℃ meter for soil supernatant and nutrient solution. It is also possible to measure soil pH directly using a pH electrode (sold separately). The main body is IP67 waterproof and the connection parts are also completely waterproof. [pH] Measurement range: 0.00 to 13.00 (when using the included electrode HI 1285-7) *The pH display on the main unit is -2.00 to 16.00 pH pH-mV: ±825mV Detection unit: 0.01 pH pH-mV: 1 mV Accuracy: ±0.02pH pH-mV: ±1mV Calibration: Automatic one-point or two-point calibration (pH 7.01 and 4.01 or 10.01) *pH 6.86 when using pH/EC simplified standard solution [EC] Measurement range: 0.00 to 6.00 mS/cm (detection unit: 0.01 mS/cm) Accuracy: ±2%FS Calibration: Automatic one-point calibration (1413μS/cm or 5.00mS/cm) *5.00mS/cm when using pH/EC simplified standard solution [TDS] Measurement range: 0 to 3000 ppm (TDS conversion rate 0.5), 0 to 3999 ppm (TDS conversion rate 0.7) Detection unit: 10 ppm Accuracy: ±2%FS Calibration: EC calibration 【temperature】 Measurement range: 0 to 50°C (display on main unit is -5.0 to 105.0°C) Detection unit: 0.1°C Accuracy: ±0.5℃ Temperature compensation: Automatic Temperature coefficient: 1.9%/℃ (percentage of change in EC/TDS with temperature change) EC/TDS conversion rate: Choose from 0.5 or 0.7 (EC to TDS conversion rate) Operating environment: 0 to 50°C (relative humidity below 100%) Waterproof: IP67 Included electrode: HI 1285-7 (Built-in pH/EC/TDS/℃ sensor, polypropylene body, 1m cable) Power supply: 3 AAA alkaline batteries (approximately 600 hours of continuous use) Automatic power off: Select from 8, 60 minutes or function OFF after non-use Size: Length 154 x Width 63 x Thickness 30mm Weight: 196g Accessories: Main unit, pH/EC/TDS/℃ electrode (HI 1285-7), 3 bags of pH/EC simple standard solution, 3 bags of electrode cleaning solution, 3 AAA alkaline batteries, Japanese instruction manual, etc. *Electrode storage solution is not included. *The soil direct pH/℃ electrode (HI 12943) is sold separately.
