Hanna HI9813-51 pH/EC/TDS/°C meter

The HI9813-51 makes it possible to perform pH, conductivity, total dissolved solids and temperature measurements with a single instrument! The special four-in-one
probe is very resistant.
The HI9813-51 is a versatile measuring instrument for agriculture, greenhouse horticulture and hydroponics.
* One instrument for 4 parameters
* Switch from one parameter to another at the touch of a button
* Special multi-parameter electrode, resistant to contaminating samples
* Water Resistant
* Adjustable TDS factor
* Automatic temperature correction of conductivity and TDS measurements

Multiparameter probe

The HI1285-51 pH/EC/TDS/°C probe is designed with a cloth junction and gel electrolyte to provide a rapid response and reduce the adverse effects of contamination.

This combination makes HI1285-5 a particularly suitable probe to withstand harsh environments such as:

fertilizer solutions.
Large LCD screen

The HI9813-51 has a large LCD display that provides pH, EC, TDS or temperature readings
along with helpful instructions. The meter is manually calibrated to one point using two trimmers. The pH is calibrated at pH 7.01, while EC/TDS is calibrated
at 1.41 mS/cm (1413 μS/cm) or 1500 ppm. The amplifier for the pH electrode prevents interference from humidity and electrical noise.
