About the HI-1285 series probes
The HI-9813-51 and HI-9813-61 are supplied with a polypropylene body pH/EC/TDS/temperature probe. The pH, EC, TDS and temperature sensor are housed in a single body that connects to the meter with a DIN connector.
Features
3 sensors in a single probe
Amplified pH electrode – The pH electrode 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 (fertiliser) present. A greater amount of salt present results in an increase in conductance.
Polypropylene body - The 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.
