The HI 991404 meter from Hanna are 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, back-lit 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. The HI 991404 also has a stability indicator and hold feature to 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. These instruments are 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 continuous monitoring applications.
The HI 991404 is supplied complete with HI 1293D pH electrode, HI 7630 EC/TDS/temp. probe (fixed), 12 VDC adapter, pH4 & pH7 buffers (20 mL each) & EC cal. solutions (1413 µS/cm) and instructions.
Uses 1500ppm or 1413 uS/cm calibration solution.
