this one has me baffled!
I have and Alkatronic and have been trying to mix reagent. it's a simple 4 to 1 mixture. I also have several bottles of Premix reagent from Coralvue. Also got concentrated reagent from Coralvue for the Alkatronic.
Using CoralVue ready to use reagent in my Alkatronic: tried with several bottles of ready to use and its very consistent.
Alkatronic = 8.87
Hanna = 8.9
Salifert reagent test = 8.9. (used reagent) x 250x 0.056 = 8.9
Actual salifert test = 9.8
My 4 to 1 mix 1 part acid + 4 parts RO. Made several batches using a scale. Each batch was a total mix of 500ml.
Alkatronic = 9.85 consistent against several batches of reagent mix.
Standard Salifert test = 9.8
Salifert reagent test = 9.8 (used reagent) x 250 x 0.056 = 9.8
Not sure what batches to believe. both reagents prove to correctly mixed.
Other Variables. used a 2nd reagent bottle for the Hanna and both tested identical. about 8.9ish
Used 2 bottles of Coralvue Ready to use reagent and get identical results
Used 2 scales and validated each
Mixed the acid 4 to 1 4 different times and got the same results
To really complicate things I also tested with my X10 and get duplicate results as the alkatronic Regardless of reagent.
Completely stumped
