Abstract
The utility model discloses a cleanable PH meter and belongs to a measuring apparatus. The cleanable PH meter is composed of a base, a cantilever, a pump and a PH electrode. A spray head is arranged at the front end of the cantilever, the cantilever is provided with a through hole to be in matching insertion connection with the PH electrode, the pump is arranged on the cantilever, an inlet of the pump is connected with a pipette, an outlet is connected with the spray head, and the rear end of the cantilever is connected with the base through a column. The PH electrode is connected with a main control unit in the base through a data transmission line of a hose. According to the cleanable PH meter, the spray head is arranged above the PH electrode, the PH electrode can be cleaned automatically after measurement, and errors are reduced and the accuracy is improved for the measurement.
Description
Technical field
The utility model belongs to instrument and equipment, is specially a kind of cleanable PH meter.
Background technology
The PH meter is a kind of instrument and equipment commonly used, is mainly used to the pH value of precision measurement liquid medium, mixes corresponding ion-selective electrode and also can measure ion electrode current potential MV value, is widely used in the fields such as industry, agricultural, scientific research, environmental protection.This instrument also is the indispensable inspection machine in food factory, potable water administrative office in a factory QS, the HACCP authentication.The PH electrode is a kind of very accurate detecting element, in use, usually contaminated even fouling, thus cause the pH value measuring error to strengthen sensitivity, bad stability.In the laboratory, the experimenter adopts the manual cleaning method to come cleaning electrode, but manual cleaning can not be clean with electrode clean, and cleaning performance is bad, affects next measurement result, causes error large.
Summary of the invention
For the problems referred to above, the utility model provides a kind of cleanable PH meter, is provided with spray head and can automatically cleans the PH electrode, and it is contaminated because repeatedly measuring to have solved the PH meter, and the problem of sensitivity is for the user brings better precision.
Cleanable PH meter of the present utility model, to be consisted of by base, cantilever, the pump housing and PH electrode, the cantilever front end is provided with spray head, and be provided with through hole and match with the PH electrode to insert and be dynamically connected, cantilever is provided with the pump housing, the entrance of the pump housing is connected with pipette, outlet is connected with spray head, and the cantilever rear end is connected with base by column.
As further improvement of the utility model, described PH electrode is connected by the interior master control set of the data line in the flexible pipe and base.
As further improvement of the utility model, be provided with display screen at base, the master control set in display screen and the base is connected with power supply.
Cleanable PH meter of the present utility model, reasonable in design is provided with spray head above the PH electrode, can be implemented in to measure to finish the rear PH electrode that automatically cleans, for surveying work has reduced deviation, improved precision.While the utility model PH electrode socket is on the PH meter, and is simple in structure, easy to carry.
Description of drawings
Fig. 1, Fig. 2 all are structural representations of the utility model cleanable PH meter.
Embodiment
Cleanable PH meter of the present utility model, to be consisted of by base 1, cantilever 2, the pump housing 3 and PH electrode 4, be provided with spray head 5 at cantilever 2 front ends, as shown in Figure 2, and be provided with through hole and match with PH electrode 4 to insert and be dynamically connected, cantilever 2 is provided with the pump housing 3, and the entrance of the pump housing 3 is connected with pipette 6, outlet is connected with spray head 5, and cantilever 2 rear ends are connected with base 1 by column 7.Base 1 is provided with display screen 8, and the master control set in display screen 8 and the base 1 is connected with power supply.PH electrode 4 is connected by the data line in the flexible pipe 9 and base 1 interior master control set.
After using the PH electrode measurement, put into the device of water in the lower end of pipette, press the lower pump body switch, the spray head automatic water jetting, the water of spray head ejection is fallen on the PH electrode, with spot flush away residual on the electrode, has kept the clean of PH electrode, make the measurement of next time not be subjected to last interference of measuring, thereby improved measuring accuracy.
