Description
Technical field:
The utility model relates to a kind of charcoal element detection industry accurately measures use portable resistor rate analyzer to resistivity value.
Background technology:
Along with the fast development of economy, people have focused on the timeliness of the equipment used in all trades and professions, convenience and Accurate Measurement function more.And the Instrument Measuring Resistivity of Carbon Products used now, be use the power supply of 220V mostly, be not easy to carry, spread of voltage, poor stability, needs back and forth to pull line, greatly strengthen the labour intensity of operator.And digital-scroll technique, Resistivity testing quantities read is inaccurate, and degree of accuracy is not high.
Utility model content:
There are provided that one is easy to carry order of the present utility model, capacity is large, voltage stabilization, can be recycled, safe and reliable, determination of resistivity accurate portable resistor rate analyzer.
The purpose of this utility model is achieved through the following technical solutions: its current/voltage test board 6 is arranged on base 1 front middle part, constant-current source circuit plate 7 is arranged on middle part on base 1 by pole 5, heating radiator 9 is arranged on constant-current source circuit plate 7 upper end by pole 5, control panel is arranged on base 1 rear end, shell 2 is sleeved on base 1 top, lithium battery 8 is arranged on middle part on base 1, and LCDs 3 is arranged on shell 2 front middle part.
The beneficial effects of the utility model are: owing to have employed advanced LCDs, fast response time, structure is simple, highly sensitive, is easy to operation, and detect quantities read accurate, measuring accuracy is high; Arrange the power supply that lithium battery instead of 220V, volume is little, lightweight, be easy to carry, capacity is large, voltage stabilization, can recycle, safe and reliable, significantly reduces the labour intensity of operator.
Accompanying drawing illustrates:
Fig. 1 is anatomical connectivity schematic diagram of the present utility model
Embodiment:
As shown in Figure 1, its current/voltage test board 6 is arranged on base 1 front middle part, constant-current source circuit plate 7 is arranged on middle part on base 1 by pole 5, heating radiator 9 is arranged on constant-current source circuit plate 7 upper end by pole 5, control panel is arranged on base 1 rear end, shell 2 is sleeved on base 1 top, and lithium battery 8 is arranged on middle part on base 1, and LCDs 3 is arranged on shell 2 front middle part.
As shown in Figure 1,4 supporting legs 4 are set bottom described base 1.
As shown in Figure 1, on described shell 2, middle part arranges handle 10.
Principle of work of the present utility model is: the sample that constant DC current is fixed by certain cross-sectional area, measures the magnitude of voltage between two probes, just can measure the resistivity of sample.
This product adopts comparatively unique technology, and can measure weak voltage very accurately, measurement can be carried out under small area analysis, after electric current is constant by electronic constant current source, and an exportable stable current value.
Method of operating of the present utility model is: 1, two ends current plug is connected A+.A-, and aviation plug connects V, (noting the position of locating slot).Select the distance L between current potential detector 2 according to the length of sample, reversal terminal and positive negative potential detector terminal are arranged on testing jig, and fixing.
2, open switch, stablize 10 minutes, by 0, the area of section value of input sample, with (cm
2) be unit.By 0, input the distance between two measuring voltage terminals, with (cm) for unit.Be connected with sample (namely two current terminals and two voltage terminals are connected with sample) by four of testing jig terminals, check whether four terminals connect well, after value stabilization to be determined, digital display value is then the resistivity of sample.Needs two current terminal according to sample can lift down use from testing jig, but no matter with testing jig or lift down use, distance between two voltage terminals is less than 1/2 of the spacing of two current terminals, as long as and be greater than 1/3. with reference to the function of keyboard, press corresponding key, without the need to calculating, the resistivity value of sample can be drawn.
