 Hanna Grochek Combo pH/EC/TDS/TEMP Monitor

The Combo meter is designed for continuous, high accuracy pH, EC/TDS and temperature measurements. These microprocessor indicators continuously monitor the three most important nutrient parameters in hydroponics, greenhouses and horticultural applications with a single instrument. These indicators feature a large, dual-level, backlit LCD to give you instantaneous readings of pH, EC or TDS and temperature, even from a distance. At startup, these indicators perform a self-check to assure proper working condition. HI 991404 stability indicator and hold features prompt the user when to take the reading and freezes the display for easy and accurate recording. Calibration and temperature compensation is automatic, while the EC/TDS conversion factor and temperature coefficient (ß) are user adjustable for application-specific measurements. The instruments are powered by a 12 volt dc transformer and are easy to install and use.
