The HI9812-5 is a simplistic pH\/EC\/TDS meter that is 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 battery life indicator as well as on-screen tutorial messages.\u003c\/p\u003e\n\u003cp\u003eThe supplied HI1285-5 probe is a polypropylene body, amplified pH electrode with a built-in EC\/TDS and temperature sensors. The amplifier for the pH electrode prevents interference from humidity and electrical noise from common sources including from motors, ballasts or pumps. The HI9812-5 is a versatile meter best suited for agricultural, greenhouse and hydroponic applications.\u003c\/p\u003e\n\u003ch5\u003eHI1285-5 polypropylene body amplified pH electrode with built in EC\/TDS and temperature sensors\u003c\/h5\u003e\n\u003cp\u003eThe HI9812-5 is supplied with a polypropylene body pH\/EC\/TDS\/temperature probe. The pH, EC, TDS, and temperature sensors are housed in a single body that connects to the meter with a DIN connector. This probe is specially engineered with a fiber junction and gel electrolyte to produce a fast response with reduced contamination.\u003c\/p\u003e\n\u003ch5\u003eAmplified pH electrode\u003c\/h5\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch5\u003eAmperometric EC\/TDS sensor\u003c\/h5\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch5\u003ePolypropylene body\u003c\/h5\u003e\n\u003cp\u003eThe polypropylene body houses all the sensors in a single body design and is durable.
