Question about Salifert Calcium Test.

[Pisquini]

I am kinda confused and wanna make sure...here are a picture of the reading I am getting from their syringe and the chart.
Am I at 485 ppm or 375 ppm?

Any help would be great. Thank you in advance!

Also, make sure when you draw the solution in,the bottom part of the black plunger is at the 1 mil line..

Wow..ok thought it was 375. My new Hanna calcium checker is off by about 100ppm then...ugh.

Hey guys this is my 1ml syringe out of my hanna kit. I am curious if I am adding too much reagent to calibrated the test? With this syringe I have been adding the number 1 picture to the vial.

With that tip on it...which line to I draw the plunger bottom to get 1ml?
1

2

Also, on the same syringe without the tip piece on where should I pull the liquid to? 1 or 2? to get 1ml.

Thanks again for any help.

Neither. That's a 1 mL syringe. The measurements you posted are 0.0&0.1. And there's no variation from tip on or off. It's the same volume

Lol sorry didn't notice its a Hanna syringe. The Salifert ones are reversed . Still, The bottom of the plunger is the measurement line...0.0 on the Hanna

Thanks Shore.....not sure why my hanna off by so much...is there a way to test my RO/DI water for calcium. It TDS meter shows 0.30 in and 0.01 out. Does that check for calcium too?

Any help would be awesome.
