The Hanna Instruments-991405 combo meter is designed for continuous, high accuracy pH, EC/TDS and temperature measurements. This microprocessor indicator continuously monitors the three most important nutrient parameters in hydroponics, greenhouses and horticultural applications with a single instrument.
Featuring a large, dual-level, backlit LCD the Hanna Instruments-991405-02 gives you instantaneous reading of pH, EC or TDS and temperature, even from a distance.
At start up, this indicator performs a self-check to assure proper working condition and the stability indicator and hold features prompts 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) is user adjustable for application-specific measurements.
The Hanna Instruments-991405 is supplied with an advanced, non-clogging double junction pH electrode and a rugged conductivity probe that will withstand even the most aggressive environments. The instruments are powered by a 12VDC transformer and are easy to install and use, making them ideal for all continuously monitoring applications.
Hanna Instruments-991405 is supplied with Hanna Instruments-1293D pH electrode, fixed Hanna Instruments-7630 probe, pH and EC calibration solutions, 12 Vdc power adapter and instructions.
