Calcium checker pre order

MG is next followed by the more coverted nitrate. But dont hold your breath for either.

are reagent refills for all the checkers $1 ea?

I think that's pretty sweet. No chance in heck my Elos tests are $1 ea.

others are cheaper, the calcium comes with a fluid and a sachet so more expensive. You mix a sachet with 1ml of fluid with the test sample.

Basic principle

Insert into checker
turn on
press once
wait for message
add 1 sachet and 1ml of fluid to the test sample
re-insert vial to checker
press button
