Abstract
The utility model relates to a hand-held water quality detecting instrument which belongs to a detecting device. The hand-held water quality detecting instrument is composed of a detecting probe and a shell body, wherein the shell body is provided with a transparent window; and a power source, a resistor and an ammeter are arranged in the shell body. A detecting sensor is arranged at the end inside the detecting probe, the detecting sensor consists of two paralleled electrodes, and the other ends of the paralleled electrodes are connected with the power source, the resistor and the ammeter respectively. The utility model has the beneficial effects that the hand-held water quality detecting instrument can be applied to detecting the drinking water quality; and the hand-held water quality detecting instrument has the characteristics that the cost is low, the measuring indications are accurate, and the carrying is convenient, thereby facilitating general consumers to use and being suitable for large-scale commercialized production.
Description
Technical field
The utility model belongs to pick-up unit, particularly relates to a kind of hand-held water quality testing meter.
Background technology
Raising along with people's living standard, the chance of out on tours and exploration increases, can not be when going out but people have with going up necessary potable water, and can only ask for nearby, but along with the quickening of process of industrialization and the development of society, water pollutes and also to be on the rise, particularly agricultural effluent in recent years, a large amount of dischargings of sanitary wastewater and industrial waste water cause rivers and lakes seriously polluted, therefore, in the open air, before the drinking-water, must guarantee that water is safety, and electrical conductivity of water (resistance) is an important index weighing water quality, it can reflect the electrolyte concentration that exists in the water outlet, electrolyte concentration is high more in the water, illustrates that water quality is poor more, otherwise explanation water quality is good more.But existing portable water quality detecting device structural design is unreasonable, the detection precision is poor, portably uses inconvenience.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of hand-held water quality testing meter is provided, and it is suitable for detects, measures indication intuitively accurately to multiple potable water.
Hand-held water quality testing meter of the present utility model is to be made of detection probe and housing, has transparent window on housing, is provided with power supply, resistance and reometer in housing.End in detection probe is provided with detecting sensor, and described detecting sensor is a parallel pole, and the other end of two parallel poles is connected with reometer through power supply, resistance respectively.
The physical and chemical index that the utility model detects can be conductivity, soluble ion concentration, also can set up mathematical model after, corresponding pH value, the total plate count index of showing.Can be with one or more directly being indicated on the micro aning ammeter dish in the above index.
The beneficial effects of the utility model are: be applicable to detection to Drinking Water water quality, have with low cost, measure indication accurately, be convenient to carry, make things convenient for ordinary consumer to use, be fit to the characteristics of large-scale commercial production.
