These meters feature a large LCD which displays either pH, EC, TDS or temperature readings along with tutorial instructions. The pH readings are displayed with a 0.1 resolution and an accuracy of +/-0.1 pH while the EC and TDS readings are displayed with a 10 mS/cm and 10 ppm (mg/L) resolution and 2% full-scale accuracy. The temperature correction coefficient (β) is fixed at 2 %/°C and allows for automatic temperature-compensated measurements of EC and TDS. These meters are calibrated manually to a single point with the use of two trimmers. pH is calibrated to pH 7.01 while EC/TDS is calibrated to either 1.41 mS/cm (1413 μS/cm) or 1500 ppm. The LCD screen has a battery life indicator as well
as on-screen tutorial messages.

No probe changes are required when switching your measured parameter between pH, conductivity and TDS. These multiparameter meters reduce the number of instruments required for daily water quality analysis.

The HI9810-61 is supplied with the HI1285-61 pH/EC/TDS/temperature probe with CAL Check. The pH, EC, TDS, and temperature sensor are housed in a single body that connects to the meter with a DIN connector.

Amplified pH electrode: The pH electrode circuit has a built-in amplifier that will reduce the effects of electrical noise on the high-impedance pH measurement. Examples of sources of electrical noise include motors, ballasts, and pumps which are common in greenhouses.

Amperometric EC/TDS sensor: The EC/TDS readings are performed by an amperometric sensor. An alternating voltage is applied to the sensor and the amount of current that passes between the two stainless steel pins is dependent upon the amount of salts (fertilizer) present. A greater amount of salt present results in an increase in conductance.

Polypropylene body: The polypropylene body houses all the sensors in a single-body design and is durable. The probe is gel-filled for maintenance-free operation. It does not have to be refilled periodically.

3 sensors in a single probe
