Tips for accurate results:
- Use Hanna HI70436 Deionized Water
- Make sure testing vials are clean of any debris
- Vials must be dry on the outside with no fingerprints
- Violent shaking will cause microbubbles that can affect the reading
- Do not let the sample sit too long before taking a reading

Have a great weekend!
It seems that the biggest/only gripe about this unit in the reviews is that it uses a powder reagent and not a liquid.
Is it really that hard to open the packet and get all of the powder in the vial?
We do not have issue with the packets, As long as the packet is shaken to the the power into one corner, The flap is then cut and the packet folded to allow the power to fall down the crease in the packet we have not had issues ourselves.
The Hanna Calcium Checker comes with enough reagent to do about 25 tests.

They do not make a Nitrate checker. If/when they do though we will bring it in.
