DESCRIPTION:
HI991404 - The new Hanna Combo Gro'Chek continuously monitors the three most important nutrient paramters in greenhouses, hydroponics, and horticulture applications. Calibration and Temperature Compensation are automatic, while the EC/TDS conversion factor and temperature coefficient (B) are user adjustable for application specific measurements. The HI991404 is supplied with an advanced, non-clogging double junction pH electrode and a rugged conductivity probe that will stand up to the most aggressive environments.
Some of the HI991404's outstanding features include:
