AEDO8 Dissolved Oxygen Water Test Kit 0.5 to 8.0 PPM

Bought it for the RAS project i recently started in Majri, Punjab. It's officially registered as first RAS of Punjab so kudos to us. I have used this machine in the eight cemented tanks and the result was accurate enough. I have also purchased the digital O2 machine too. And both shows nearly similar results. I would suggest fellow viewers to buy the digital one if they also are going to use in Fishery work where there are more number of tanks. As we also run hatchery and that's where i feel this product is slow in showing results.

Ok

Good

RECEIVED BROKEN TEST TUBE GLASS BOTTLE INSIDE THE BOX. CARELESS PACKAGING . THIS BOTTLE IS UNIQUE NOT AVAILABLE IN OPEN MARKET. NOW THIS PRODUCT BECOMES USELESS.

Ever since I took it, I have been able to use it 6-7 times because the bottle that was found with it broke and has been kept like that ever since. Can I have that bottle again? Because I have not found many places yet. What can be done?

Exact product

Have been using the kit for more than 2 years. It is fairly accurate. When business or deep-research applications are involved - take a preliminary reading of one year PATTERN of readings - for a broad and approximate overview using AQUASOL kit. You will find the trouble spots on a river/stream in this field review. Specific detailed studies would involve a Central Government/State Government Certified Laboratory to take DO Tests on Control Samples. Unless we have a mobile van laboratory we cannot take RECOMMENDED On-the-Spot DO readings. The AQUASOL DO Testing kit helps to find broad patterns of pollution in a stream/river on the basis of which more detailed laboratory equipment can be utilized. The kit is low cost and easy to use by young high school and college students in the field. If you have doubts about a particular kit, you can calibrate by spending more money and doing the calibration with help of a professional water quality testing laboratory.
