[Portable DO Meter with mg/L and % Modes]: The dissolved oxygen test kit with two modes: mg/L mode (dissolved oxygen content in water, 1mg/L=1ppm) and % mode (saturation percentage). Easily obtain accurate oxygen content in the solution. Professional oxygen monitoring equipment is used in koi ponds, drinking water analysis, home beer and wine brewing, industrial systems, hydroponic nutrient, fish tank, sewage treatment, wastewater treatment, laboratories, education research and other fields.
[Digital Dissolved Oxygen Meter Kit with 3m Electrode Cable]: GIDIGI dissolved oxygen tester with a 3m electrode cable. With this dissolved oxygen test kit, you can test the oxygen content in deeper water and avoid the problem that the electrode cannot touch the water due to distance. It is very convenient to carry and is very suitable for outdoor water quality measurement and environmental monitoring (lakes, rivers, large ponds and aquaculture and other aquatic systems).
[Automatic Temperature Compensation and Manual Salinity and Altitude Compensation]: The GIDIGI dissolved oxygen test kit with ATC function, the test values are more stable. By connecting to the phone APP via Bluetooth, you can also set salinity compensation and barometric pressure compensation to obtain more accurate test values. The DO tester is a nice assistant for marine fish and other aquatic life breeding enthusiasts. In addition, through the APP, you can store, manage and share test data
[Easy to Use and Calibrate]: GIDIGI dissolved oxygen tester comes with detailed instructions and complete accessories (replaceable membrane cap, electrolyte and zero oxygen water). No need to buy calibration solution, easily calibrate the tester. Simple operation, just put the tester electrode into the test solution to quickly obtain accurate oxygen test value. And you can easily get membrane cap and calibration solution by browsing GIDIGI store.
[GIDIGI Service for Every Customer]: GIDIGI dissolved oxygen meter with digital backlight LCD display, which can easily obtain readings in dim environments, and has data lock function and temperature switching function (℉/℃). GIDIGI support 365-day warranty, so there is no need to hesitate to place an order. If you have any questions, please email us and we will respond to you within 24 hours. We are happy to solve any product problems for you.

Very accurate and comes in handy for multi purpose uses
Versatile and reliable tool designed for anyone who needs accurate water quality measurements. With its 6-in-1 functionality, it combines multiple testing capabilitiesâpH, PPM (TDS), EC, salinity, temperature, and ORPâinto one compact device, making it an excellent choice for aquariums, hydroponics, pools, spas, brewing, and drinking water monitoring. The meter has a modern, handheld design that is lightweight and easy to use. The LCD screen is bright and clear, displaying multiple readings simultaneously for quick analysis. The body feels sturdy enough for both home and professional use, and the included ORP 222mV calibration solution is a thoughtful addition for maintaining accuracy over time. Accuracy is where this device truly shines. With its advanced sensors and simple calibration process, it provides highly reliable readings across all six parameters. The fast response time makes it especially useful for daily testing routines, whether youâre balancing pool chemicals, monitoring a hydroponic system, or ensuring safe aquarium conditions. This tester is designed with user convenience in mind. The one-button operation and straightforward calibration steps make it accessible even for beginners. Switching between measurement modes is seamless, and the waterproof probe ensures it can withstand repeated use in wet environments without issue. Few testers offer this level of versatility in a single device. Itâs particularly useful for users who manage multiple water systems, such as hydroponics enthusiasts who also maintain aquariums or home brewers who need to monitor pH and TDS levels precisely. Its multifunctionality eliminates the need for multiple separate tools, saving both cost and storage space.

Appears to be solid unit
Solid unit and simple to operate. No serious flaws. Comes with almost everything you will need to calibrate and use the meter. Note that to make-up the calibration solutions, you will need some plastic screw cap bottles for storage along with a semi-accurate way to measure out the required amount of distilled water. Obviously, you will also need distilled water, but I don’t hold that against the device for simple packaging reasons.Very easy to read backlight display and simple push button operation. Will the accuracy match a precision laboratory meter … I don’t know, but it appears to give numbers accurate enough for simple day-to-day household use based on comparison with high-quality test strips. I prefer this type of unit over the tiny flat-pen style units but then again those can be found at a lower cost if you only need a single test or maybe just once or twice a year. I would have preferred to see a AA or AAA battery over the little coin cells but as long as self-discharge is under control when its “off”, that shouldn’t be a big issue. Both the battery compartment at the top and the probe cover have O-rings and appear to be well sealed to keep the battery area dry and the probe area wet. Do keep the probe moist / wet. Letting it dry out by losing or just not replacing the cap is not a great idea.If you do plan on a lot of semi-careful measurements, you might want to pick up additional calibration packets. The kit will get you started with one each of the 4, 7, and 10 pH buffers but these don’t have an infinite shelf life after mixing. Even in well-sealed plastic bottles, these will probably become questionable after 30 – 60 days due to CO2 exposure from the air, evaporation, plus how often you open and close the containers. The dry packets are convenient because you have a fresh solution when you mix it and no question about age. The dry powder packets don’t expire; you can put them in a drawer for 10 years then make fresh and accurate calibrants when you need. The pre-made liquid solutions have an initial shelf-life of a year or so but that drops to a month or so as soon as you open the bottle for the first time. It looks like the dry packets run about $7 or so for a set of 5 each 4, 7, 10 buffers. This should be expected for any pH meter, not just tis one.

Not Super Accurate But Good Enough
For what it costs, this is a solid little tool and Iâm glad I bought it. I mainly use it to check the pH levels and the ORP in my pool – I haven’t used any of the other functions. When I compare with my liquid-drop testing it’s not pinpoint-perfect, itâs accurate enough to get the job done. It also includes a few extra features that could come in handy if I ever want to test pool water or other things, which is a nice bonus. Though it wasn’t a big deal, I didn’t enjoy calibrating the device, it wasn’t a big deal, but just one more step if you want it to be accurate. My box was missing one of the chemical envelopes to help calibrate the device.The price feels reasonable, and the display is clear and easy to read. Results come up fast, and overall itâs a reliable device. Good if you’re in a hurry and don’t have time to do the drop test on the pool – it will get you “in the ball park.”
