Electrical noise can come from motors and pumps that are common in greenhouses. The single reference junction design of the pH electrode has a cloth junction that allows ion movement between the inner gel electrolyte and the sample being measured. The advantage of the cloth junction is that it can be extracted from the probe,  exposing a fresh surface when readings become drifty or erratic. These features make this probe ideal for use in fertilizer solutions.\u003c\/p\u003e\n\u003ch5\u003eAmperometric EC\/TDS Sensor\u003c\/h5\u003e\n\u003cp\u003eEC\/TDS readings are performed by a two-pin amperometric sensor. An alternating voltage is applied to the sensor and the amount of current that passes between the two stainless steel pins determines the amount of dissolved ionic solids present.\u003c\/p\u003e\n\u003ch5\u003eBuilt-In Temperature Sensor\u003c\/h5\u003e\n\u003cp\u003epH and EC\/TDS readings must be temperature compensated in order to obtain accurate results. The built-in temperature sensor of the HI1288 provides a speedy temperature reading which is then used to adjust the pH and EC\/TDS results accordingly.\u003c\/p\u003e\n\u003ch5\u003ePolypropylene Body\u003c\/h5\u003e\n\u003cp\u003eThe polypropylene body of the HI1288 houses all three sensors within a sturdy,  single body design. This body material is suitable for a wide range of applications and excels in measurements with portable meters due to its durability. The fins around the spherical glass pH bulb minimizes breakage due to accidental bumping or dropping of the electrode. The polypropylene plastic is a high quality plastic that is chemically resistant to many aggressive chemicals.\u003c\/p\u003e\n\u003ch5\u003eDIN Connector\u003c\/h5\u003e\n\u003cp\u003eThe HI1288 uses a DIN connector. This type of connector is generally proprietary to the meters they are supplied with and may not be interchangeable. The HI1288 is made for use with Hanna’s HI991300 and HI991301 portable multiparameter meters.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI1288\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e HI1288 pH\/EC\/TDS Multiparameter Probe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReference Cell Type\u003c\/td\u003e\n\u003ctd\u003e HI1288\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eJunction Type\/Flow Rate\u003c\/td\u003e\n\u003ctd\u003e cloth\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType of Electrolyte\u003c\/td\u003e\n\u003ctd\u003e gel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003e polypropylene\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGlass Type\u003c\/td\u003e\n\u003ctd\u003e LT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTip \/ Shape\u003c\/td\u003e\n\u003ctd\u003e spheric (8 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMatching Pin\u003c\/td\u003e\n\u003ctd\u003e no\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax.
