Abstract
The utility model relates to a portable handheld tester for dissolved oxygen. The portable handheld tester mainly comprises an equipment mainboard, membrane keys, a liquid crystal display screen, a power supply and a dissolved oxygen and temperature test probe, wherein the membrane keys, the liquid crystal display screen and the dissolved oxygen and temperature test probe are directly connected with the mainboard respectively, the power supply supplies power to a system, and a microprocessor memory and a clock chip are integrated on the equipment mainboard. The portable handheld tester is small in volume and convenient to carry, and can test and display the dissolved oxygen content in water and water temperature in real time on site.
Description
Technical field
The utility model belongs to the tester field, relates in particular to a kind of portable dissolved oxygen DO handheld meter.
Background technology
The dissolved oxygen DO tester is an instrumentation of measuring the content that is dissolved in the oxygen in the WS.Oxygen is dissolved in the water through ambient air, air flow and photosynthesis.Can be used to measure the flow process that is used for can influencing oxygen content reaction velocity, flow path efficiency or environment monitors: like aquaculture, biological respinse, environmental testing (lake, small stream, ocean), water/wastewater treatment, Production of Wine etc.
Present dissolved oxygen DO tester is main with desktop computer basically, adopts septum electrode to make transducer more, converts oxyty (being actually partial pressure of oxygen) to electric signal, through amplifying, adjusting (comprising salinity, temperature compensation), is shown by analog to digital conversion again.The membrane electrode that the dissolved oxygen DO tester is practical has two types: polarogram type (Polarography) and galvanic cell type (Galvanic Cell).The dissolved oxygen DO tester has easy for installation, and the demarcation cycle is long, to characteristics such as other materials are insensitive, and can monitor electrolytical operating position in overlay film and the probe, and generally each changed once electrolytic matter and overlay film to 3 years.
Existing technology provides a kind of portable dissolved oxygen DO handheld meter, can on-site real-time detects and shows dissolving and oxygen content water temperature in the water, can carry, and uses convenient.
Summary of the invention
The purpose of the utility model provides a kind of portable dissolved oxygen DO handheld meter, can on-site real-time detect and demonstration oxygen in water content and water temperature.
The technical scheme of the utility model is: portable dissolved oxygen DO handheld meter comprises equipment mainboard, film key, LCDs, power supply and dissolved oxygen DO and temperature test probe.Wherein membrane keyboard directly is connected with mainboard respectively with LCD, dissolved oxygen DO and temperature test probe, and power supply is system's power supply, is integrated with microprocessor memory and clock chip on the said equipment mainboard.
The advantage and the good effect of the utility model are: volume is little, is convenient for carrying, and can on-site real-time detect oxygen in water content and temperature, and show test value through LCDs.
