Hanna Instruments offers a wide variety of electrodes that are designed for many different applications. The sensing material, body material, and connection type used are just some of the design considerations.
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
