Abstract
The utility model relates to a polarimeter and particularly relates to a novel temperature control device for the polarimeter. According to the technical scheme, the novel temperature control device mainly consists of a detection chamber, an electro-thermal material layer, a control circuit and a temperature sensor. The temperature sensor is arranged in the detection chamber; the electro-thermal material layer is arranged on the surface of the detection chamber; and the electro-thermal material layer is connected with the control circuit to control a temperature of the detection chamber. The novel temperature control device for the polarimeter provided by the utility model has the beneficial effects that a temperature control system for the polarimeter is additionally arranged, so that influences on a detecting result, caused by a temperature, are reduced when an optical activity of a sample is detected, so that detection data is more accurate and more reliable.
Description
Technical field
The utility model relates to a kind of polarimeter, particularly a kind of novel polarimeter attemperating unit.
Background technology
Polarimeter is an instrument of measuring the material optical activity, through the measurement to the sample optical activity, can analyze concentration, content and the purity etc. of confirming material.Be widely used in commercial production such as pharmacy, medicine inspection, sugaring, food, spices, monosodium glutamate and chemical industry, oil, scientific research, teaching department are used for the control of assay or procedure quality.Wherein, temperature is a key factor that influences optical activity, and the temperature rising can make polarization tube expand and the length lengthening, thereby causes the density of testing liquid to reduce.In addition, temperature variation also can make the intermolecular generation of test substance associate or disassociation, and optical activity is changed.Existing polarimeter is not provided with special-purpose attemperating unit, causes measurement data not accurate enough.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of novel polarimeter attemperating unit is provided, and makes measurement effect more accurate.
Its technical scheme is: mainly be made up of sensing chamber, thermo electric material layer, control circuit and temperature sensor; Sensing chamber inside is provided with temperature sensor; Be provided with the thermo electric material layer on the surface of described sensing chamber, the thermo electric material layer connects the temperature of control circuit with the control detection chamber.
The beneficial effect of the utility model is: increased the temperature control system of polarimeter, when the test sample optical activity, reduced the influence of temperature to testing result, made and detect data more accurately and reliably.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: sensing chamber 1, thermo electric material layer 2, control circuit 3 and temperature sensor 4.
Embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of sensing chamber 1, thermo electric material layer 2, control circuit 3 and temperature sensor 4; Sensing chamber 1 inside is provided with temperature sensor 4; Be provided with thermo electric material layer 2 on the surface of described sensing chamber 1, thermo electric material layer 2 connects the temperature of control circuit 3 with the control detection chamber.
This device is placed in bottom, digital display polarimeter sample chamber, is used to control the temperature of sample to be checked, and the surface electrical hot material layer adopts the thermo electric material of electric jacket, and control system adopts closed-loop control system, makes this device can reach accurate automatic temperature-control and heating.
During use, when the test sample temperature is lower than the detected temperatures that needs, open heating arrangement, the control detection sample is in the testing result of uniform temperature.
