Portable pH/EC/TDS/Temperature Meter Hanna HI9813-51 HI 9813-51

Portable pH/EC/TDS/Temperature Meter Hanna HI9813-51 HI 9813-51 Descriptions : pH/EC/TDS/Temperature Portable Meter, range: pH 0.0 to 14.0 pH EC 0.00 to 4.00 mS/cm TDS 0 to 1999 ppm (mg/L) The HI9813-51 is a portable, water resistant meter that is designed for measuring pH, EC/TDS, and temperature when paired with its respective probe (i.e., HI1285-51). The meters are easy to use, with dedicated keys for measurement modes that are clearly displayed on the LCD, and knobs for 1-point calibration of pH and EC. On-screen tutorial messages guide the user through calibration and measurement. Main Features : - 3-in-1 combination probe with pH, EC/TDS, and temperature sensors - Best for hydroponics, greenhouses, farming, and ground water app. Specifications : pH Range 0.0 to 14.0 pH pH Resolution 0.1 pH pH Accuracy (@25°C/77°F) ±0.1 pH pH Calibration Manual, 1-point Temperature Range 0.0 to 70.0°C Temperature Resolution 0.1°C Temperature Accuracy (@25°C/77°F) ±0.5°C Temperature Calibration Automatic from 0 to 70°C with ß=2% / °C EC Range 0 to 4000 µS/cm EC Resolution 0.01 mS/cm EC Accuracy (@25°C/77°F) ±2% F.S.
