Description
Technical field
The utility model belongs to species analysis Instrument technology field, specifically just relates to a kind of built-in temperature sensor formula pH electrode to temperature fast response.
Background technology
PH electrode also known as pH probe, pH sensor, be the part that PH meter contacts with measured matter, be used for survey electrode potential device.In elemental analysis field, temperature can affect the pH value of detected solution and the potential difference (PD) of electrode, and because the temperature variant pH value of solution is unknown, therefore when measuring, temperature compensation is very important to accuracy of measurement.For the measurement of precision, must serviceability temperature sensor or use the pH electrode of built-in temperature sensor.
As shown in Figure 1, the pH electrode of traditional built-in temperature sensor, thermistor is placed in the protection tube of falling heat-transfer glue usually, and is placed in the center of responsive ball bubble, is full of solution in electrode around.Due to interior solution thermal conductivity poor-performing, therefore to make that the temperature of thermistor is consistent with sample needs the longer time.The response of electrode pair temperature variation is slow, thus adds the test duration.And if the temperature of sample is constantly in change, delayed temperature-responsive can cause larger measuring error.
Utility model content
The purpose of this utility model is exactly for the delayed technological deficiency of the pH electrode pair solution temperature reacting condition of existing built-in temperature sensor, a kind of built-in temperature sensor formula pH electrode to temperature fast response is provided, can be identical with measured matter temperature rapidly by own temperature, improve measuring accuracy.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of built-in temperature sensor formula pH electrode to temperature fast response of the utility model design, it comprises electrode shell, described electrode shell leading portion is equipped with responsive ball bubble, electrode shell and responsive Qiu Pao UNICOM, it is characterized in that: thermistor puts in responsive ball bubble from electrode shell and steeps bottom with responsive ball to be close to, glass protection pipe is set with outside thermistor, glass protection pipe stretches in responsive ball bubble from electrode shell, described glass protection pipe front end oral area is close to responsive ball bubble inwall, steep in thermistor is wrapped in by part falling heat-transfer medium that inwall is close in glass protection tube cavity with responsive ball, glass protection pipe and responsive ball steep the outside that inwall is close to and are coated with anti-aqueous medium, in the part that anti-aqueous medium makes glass protection pipe and responsive ball bubble inwall be close to is full of in steeping with responsive ball, reference solution is isolated, interior reference filamentary silver to stretch in responsive ball bubble reference solution from electrode shell.
Further, described glass protection pipe front end oral area is bell, and bell is close to responsive ball bubble inwall.
Further, fill outer reference solution in described electrode shell, outer reference filamentary silver stretches in outer reference solution, and Ye Jie circle is located on electrode shell.
Further, described anti-aqueous medium is the combination of single component silica gel or two component silica gel or epoxy resin or this three sample.
Beneficial effect
A kind of built-in temperature sensor formula pH electrode to temperature fast response that the utility model electrode provides, in use procedure, thermistor sticks to responsive ball bubble inner side by heat-conducting medium all the time, can be identical with measured matter temperature rapidly by own temperature, thus obtain temperature-responsive speed faster, improve measuring accuracy.
