The pH portion of this probe is constructed with a cloth junction, maintenance-free polymer gel electrolyte, and a low-temperature glass sensing bulb. The EC\/TDS portion of this probe utilizes two stainless steel pins for an amperometric determination of conductivity and total dissolved solids.\u003c\/p\u003e\n\u003cdiv class=\"break\"\u003eA built-in temperature sensor ensures that both pH and EC\/TDS readings are compensated for temperature variations in both standards and samples. The design consideration for the HI1285-7 is ideal for measuring the pH, EC\/TDS, and temperature in greenhouses, hydroponics, and other agricultural applications.

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\/div\u003e\n\u003cdiv class=\"break\"\u003e\n\u003ch2 class=\"head1\"\u003e\u003cstrong\u003eAmperometric EC\/TDS Sensor\u003c\/strong\u003e\u003c\/h2\u003e\nEC\/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\/div\u003e\n\u003cdiv class=\"break\"\u003e\n\u003ch2 class=\"head1\"\u003e\u003cstrong\u003eBuilt-In Temperature Sensor\u003c\/strong\u003e\u003c\/h2\u003e\npH and EC\/TDS readings must be temperature compensated in order to obtain accurate results.

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\/div\u003e\n\u003cdiv class=\"break\"\u003e\n\u003ch2 class=\"head1\"\u003e\u003cstrong\u003eQuick Connect DIN Connector\u003c\/strong\u003e\u003c\/h2\u003e\nThe HI1285-7 uses a Quick Connect DIN connector that makes attaching and removing the probe simple and easy.
