Description
Technical field
This utility model relates to field of experiment equipment, particularly relates to a kind of temperature control for measuring temperature and resistivity relation
Formula electric conductivity test device.
Background technology
Laboratory is faced with an important problem for sample detection and cannot realize temperature and resistivity now
Testing, this allows for some laboratory samples simultaneously, when needing to measure its resistivity and temperature relation, does not has effective way to obtain
The experimental data needed, therefore causes certain restriction for present experimentation.Simultaneously for being heated to uniform temperature
The resistivity measurement of sample, be also faced with a urgent problem, namely for the detection when heating of detection sample,
The impact on it of ambient temperature and moving air cannot be eliminated.It is therefore necessary to research one can be exclusively used in test temperature and electricity
The test device of resistance rate relation.
Utility model content
Control unstable for overcoming existing conductivity measurement cannot accurately measure temperature with the relation of resistivity or temperature
Deng not enough, technical problem to be solved in the utility model is: provide the one can stability contorting heating-up temperature, it is simple to measure temperature
Degree and the test device of resistivity relation.
This utility model solves its technical problem the technical scheme is that temp.-controlled type electric conductivity test device, including
Four probe resistance rate testers, temperature controller and contact temperature-measuring meter, also include a temperature control box, and described temperature controller is positioned at temperature control box
Bottom, temperature control box top is provided with two openings, the probe of four probe resistance rate testers and the probe of contact temperature-measuring meter and divides
Do not penetrate into temperature control box in two openings.
Further, the inwall of described temperature control box is provided with glass fibre cotton.
Further, the side of described temperature control box is provided with chamber door.
The beneficial effects of the utility model are: by arranging a temperature control box, be placed on by temperature controller bottom temperature control box,
Two openings are opened by putting into the probe based on four probe resistance rate testers and contact temperature-measuring in temperature control box top, when needs are to survey
When test specimen carries out adding thermal measurement, temperature control box can completely cut off extraneous factor to be affected the temperature of test block, thus ensure that the standard of measurement
Really property, meanwhile, whole apparatus structure is compact, takes up room little, is particularly suitable for laboratory applications.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Figure is labeled as, 1-tetra-probe resistance rate tester, 2-temperature controller, 3-contact temperature-measuring meter, 4-temperature control box, 5-glass
Glass cellucotton, 6-chamber door, 11-probe, 21-heating surface, 31-pops one's head in, 41-opening.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
As it is shown in figure 1, this utility model bag four probe resistance rate tester 1, temperature controller 2 and contact temperature-measuring meter 3, also wrap
Including a temperature control box 4, described temperature controller 2 is positioned at the bottom of temperature control box 4, and temperature control box 4 top is provided with two openings 41, four probe electricity
The probe 11 of resistance rate tester 1 and the probe 31 of contact temperature-measuring meter 3 penetrate into temperature control box 4 respectively in two openings 41.
Using method of the present utility model is, is first put in temperature control box 4 by the test block needing testing conductivity, is placed on temperature control
On the heating surface 21 at device 2 top, then connect the probe 11 of four probe resistance rate testers 1 and contact temperature-measuring meter 3
Probe 31, finally opens temperature controller 2 and heats test block, by four probe resistance rate tester 1 and contact temperature-measuring meters 3
Data show and draw the experimental result wanted.This utility model relative to the method for testing of traditional open type, because of
The isolation of temperature control box 4 factor to external world, can be effectively improved certainty of measurement, draws conclusion more accurately.
When using temperature controller 2 that test block is heated, in order to be hedged off from the outer world as far as possible, it is to avoid temperature control box 4 internal with
Extraneous formation heat exchange, is provided with glass fibre cotton 5 on the inwall of described temperature control box 4.Glass fibre cotton 5 has the most heat insulation
Effect, on the one hand can ensure the stability of temperature control box 4 internal temperature, is on the other hand also possible to prevent temperature control box 4 outside wall temperature liter
High impact operates or causes the security incidents such as scald.
For the ease of experimental implementation, it is provided with chamber door 6 in the side of described temperature control box 4.Chamber door 6 is easy to put into and connecting test
Part, chamber door 6 should arrange unnecessary glass fibre cotton 5 with the junction of temperature control box 4, it is to avoid forms air flowing at gap.
This utility model simple in construction, makes convenient to use, only just can be eliminated ectocine by simple combination,
Thus accurately measure the relation of temperature and resistivity, there is for experiment appliance good practicality and application prospect.
