Hanna HI9813-5 Water-resistant pH/EC/°C meter

The HI9813-5 allows you to take pH, conductivity, total dissolved solids and temperature measurements with a single instrument! The special four-in-one probe is highly resistant. The HI9813-5 is a versatile measuring instrument for agriculture, 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 polluting samples
• Water-resistant
• Adjustable TDS factor
• Automatic temperature correction of conductivity and TDS measurements

Multiparameter probe

The HI1285-5 pH/EC/TDS/°C probe is designed with a cloth-junction and gel electrolyte to achieve fast response and reduce the adverse effects of contamination.

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

• Fertiliser solutions.
• Large LCD display

HI9813-5 has a large LCD screen that displays pH, EC, TDS or temperature readings, along with convenient instructions. The meter is manually calibrated at 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.
