HI-991404 pH/EC/TDS/Temperature Monitor information

Hanna's extended description




The HI-991404 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.

The HI-991404 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 instrument is powered by a 12VDC transformer and easy to install and use, making it ideal for all continuously monitoring applications.




Mains powered - All mains operated equipment is compatible with UK AC voltage and frequency – 230V, 50Hz.



Replaceable Electrode – No need to replace the whole meter when the electrode needs replacing. Spare and replacement electrodes are available for this product.
