The Hanna GroCheck Combo Meter uses professional-grade sensors to test pH and TDS in one simple-to-use unit. The Combo Meter displays results clearly so users can check their readings quickly while the meter's durable water-proof casing ensures longevity.
HannaThe meter ranges are: pH with range 0-14 and TDS with range 0-1990 ppm. pH readings have an accuracy of ±0.2 and TDS has an accuracy of ±2%. The calibration is manual for pH at 1 or 2 points and manual for TDS at 1 point. The adjustable setpoints for the meter are: 3.0 to 7.0 for pH and 500 to 1600 ppm for TDS. For added security, if readings deviate from the setpoint the customer chooses, an alarm flashes for either pH, TDS or both. The GroCheck Combo Meter comes with replaceable probes, a 12VDC adapter with a 6.6' power cord, a grounding bar that helps probes last longer and gives more accurate pH readings, calibration solution, a calibration screwdriver and instructions. The meter carries a 2-year warranty and the probes each carry a six-month warranty.
