A pH electrode with general purpose (GP) glass will have a resistance of 100 megaohms at 25℃ while the resistance of LT glass is around 50 megaohms at 25℃. As the temperature of the glass decreases in the sample,  the resistance of the LT glass will approach that of GP glass. If using GP glass,  the resistance would increase above the optimum range,  resulting in increased impedance and ultimately affecting the measurement. The HI62911D is suitable to use with samples that measure from 0 to 80℃.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: flex-start; gap: 16px 24px;\"\u003e\n\u003cdiv style=\"flex: 0 0 140px; max-width: 100%; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/porous-ptfe-junction.png\" alt=\"flat tip bulb\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 200px; min-width: 0;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eFlat Tip Bulb\u003c\/h4\u003e\n\u003cp\u003eThe recessed flat tip bulb of the HI62911D is easy to clean and prevents solids in solution from collecting on the sensor.

In a system without a matching pin,  electrical currents in the sample can affect the reference half-cell voltage that is connected via the liquid junction with the sample. In this case,  the reference electrode picks up the electromagnetic fields and the measurement of the pH is altered. The matching pin isolates these current\/magnetic fields from the reference electrode. The HI62911D titanium body serves as a matching pin for safe precise pH measurements.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: flex-start; gap: 16px 24px;\"\u003e\n\u003cdiv style=\"flex: 0 0 140px; max-width: 100%; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/porous-ptfe-junction.png\" alt=\"flat tip bulb\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 200px; min-width: 0;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003ePTFE Junction\u003c\/h4\u003e\n\u003cp\u003ePorous polytetrafluoroethylene (PTFE) is a hydrophobic material that is available with different porosities.

As depicted by the figure above,  these electrodes have only a single junction between the internal reference wire and the external solution. Under adverse conditions,  such as high pressure,  high temperature,  highly acidic or alkaline solutions,  the positive flow of the electrolyte through the junction is often reversed resulting in the ingress of sample solution into the reference compartment. If this is left unchecked,  the reference electrode can become contaminated,  leading to complete electrode failure. Another potential problem with single junction electrodes is the clogging of the junction due to silver chloride (AgCl) precipitation. Silver can be easily precipitate in samples that contain Tris buffer or heavy metals. When the electrolyte solution makes contact with the sample,  some AgCl will precipitate on the external face of the junction. The result is drifty readings obtained from the sensor.\u003c\/p\u003e\n\u003cp\u003eHanna's double junction system,  as the name implies,  has two junctions,  only one of which is in contact with the sample as shown in the figure. Under adverse conditions,  the same tendency of sample ingress is evident. However,  as the reference electrode system is separated physically from the intermediate electrolyte area,  the contamination of the electrode is minimized. The likelihood of clogging of the junction is also reduced with a double junction electrode since the outer reference cell uses a fill solution that is \"silver-free\". Since there is no silver present,  there is no precipitate that can form to clog the junction.\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 HI62911D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Titanium Body pH Electrode for Plating Baths with DIN Connector - HI62911D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003e pH: 0 to 13\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReference Cell Type\u003c\/td\u003e\n\u003ctd\u003e double, Ag\/AgCl\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eJunction Type\/Flow Rate\u003c\/td\u003e\n\u003ctd\u003e PTFE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType of Electrolyte\u003c\/td\u003e\n\u003ctd\u003e polymer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003e titanium body working as matching pin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTip \/ Shape\u003c\/td\u003e\n\u003ctd\u003e flat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMatching Pin\u003c\/td\u003e\n\u003ctd\u003e yes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax.
