Best Dissolved Oxygen Sensors of 2018
Buying Guide and Advice

Best dissolved oxygen sensors
A dissolved oxygen sensor is an instrument used to measure the amount of oxygen in a liquid. There are many dissolved oxygen sensors on the market but allow me to just take you through the four best dissolved oxygen sensors. Let us not be ignorant on knowing how these apparatus work. I believe that for one to know the best machine on the market one has to know how it works. There is no big difference when it comes to how a pregnancy test kit works and the dissolved oxygen sensor. I am assuming that we know how the pregnancy kit works. Both of them give the results on the principle of concentration of progesterone for pregnancy kit and oxygen for the dissolved oxygen sensor.
Apera instruments A1480 DO850 Optical Dissolved Oxygen Meter.
Describing this sensor as a superior sensor is an understatement. This sensor is advanced technology, starting with the auto lock mode of display all the way to a stable reading. This makes the results to be accurate. This meter can be used in any kind of solution without the fear of being damaged; it is water proof hence the internal elements are very safe. The stands of this meter are very flexible, after use you can fold them and put them in the carrying case which is provided when you purchase the meter. The results are obtained within a very short period of time and the accuracy of the results is a guarantee.
Unlike the probes of the other sensors, this one does not absorb oxygen and it is not confined to measure a certain amount of water since this has the ability to even measure flowing water. I promise you; once you buy this sensor life becomes easy when it comes to worries about the maintenance. The maintenance is offered free of charge. By just turning the sensor on you are good to start measuring the amount of oxygen in the liquid because there is no calibration of the figures.
Sensorex DO1200/T Galvanic Dissolved oxygen sensor
This is one of the best sensors on the market. This is the sensor that will save the headache of maintaining. When it comes to cleaning the membrane it is recommended for one to use a soft piece of cloth to avoid scratching the membrane. With proper cleaning and use of the membrane, durability is assured. The sensor takes less time to give the results. Its approximated time is around five minutes which is good. Let us not even talk about its accuracy level which is very exemplary.
The body of this sensor is made of Noryl, the anode part is made of silver and the cathode is of zinc. The diameter of the sensor is approximately 6 centimeters with a length of approximately 18 centimeters. The probe is the one that is responsible for signaling. The strength of the signal is determined by the amount of oxygen available in the liquid being tested. The upper part of the probe has the cable, cathode, and anode while the lower part has a screw which attaches it to the membrane cap.
YSI Pro Series Galvanic Dissolved oxygen sensor
This is one of the oldest on the market; it has been modified ever since to suit the advancing technology which is evolving each day. This sensor is very fast when it comes to giving results; this is brought about by the fact that by just turning on the sensor you are good to go, unlike some other sensors where you have to calibrate the measurements before testing. one disadvantage of this sensor is that the anode is consumed even when the sensor is turned off, this makes the lifespan of the anode to be decreased to six months compared to that a polarographic sensor which is twelve months.
The probe should be cleaned after use so as to ensure the results obtained are accurate; it should be replaced in case of a crack. You don’t have to worry about the cost of purchasing another membrane when the one in use is damaged; you are given six more membranes to replace. The membrane is attached by use of screws; this makes it absolutely simple for anyone to replace with minimal use of the manual. This sensor is pocket-friendly since it has a 3% discount.
Accurate and robust dissolved oxygen sensor
This is one of the best dissolved oxygen sensors on the market. Sometimes when something gets in water it tends to be a little slippery, this sensor is designed in such a way that it has a firm grip even after it has been dipped in water. This sensor has a lot of electrolytes. It has a thin membrane that is easy to replace once it is used. Since this membrane is organic it allows oxygen to diffuse through the electrodes as well as the electrolyte. Everyone wants a device that is easy to maintain this is the best sensor when it comes to maintaining. When it comes to the speed in giving results this sensor has taken the credit, it gives accurate results within a very short time. Once this machine has been set up, it will take a long time before it is set up again.
Just like many devices sold these apparatus have a one year warranty. If it breaks down before the warranty has expired the damages will be fixed free of charge. The sensor part is like a cylinder made of ceramic and has platinum electrodes. These electrodes are protected with a metal gauze.
These dissolved oxygen sensors have made it easy for someone to carry out aqua farming. Farmers won’t suffer loss due to lack of oxygen in the water leading to the death of fish and many other aquatic animals. As I said earlier there are many dissolved oxygen sensors on the market because but I chose to discuss the above four. From the above sensors, you can choose the one that best meets your needs.
