Hanna Instruments pH/EC/TDS/°C meter
Model HI 9813-6: We've used this meter in our shop for years and it's still in excellent working condition. The multi-parameter meter tests 3 of the most important factors for hydroponics: pH, EC, TDS and Cal-Check feature to assess calibration status.
A rugged all-round waterproof meter, the HI 9813 has a fast response probe to test pH from 0.0 to 14.0, EC from 0.0 to 4.00 mS/cm and TDS from 0 to 1999 ppm (mg/L).
This Hanna Instrument meter is easy to calibrate and the probes are easily replaced. It has a history of durabilty that you can depend upon.
Battery life is about 150 hours of continuous use. Uses one 9V alkaline battery (included). Weighs only 8.8 ounces. Dimensions: 6.5 x 3 x 1.8 inches.
