Calcium reference kit HI758-11

Calcium reference kit HI758-11 for the Hanna HI758 Calcium checker

This kit contains two sealed bottles: one with a reference value of 0 and another with a liquid that simulates a calcium level of 400 ppm.

Usage:

• First, clean both cuvettes using a soft cloth that does not scratch. Handle them only by the cap to avoid leaving fingerprints that may affect the test.
• Next, turn on the checker and place the clear cuvette (labeled A) in the holder, then press the button.
• When “C. 2” appears on the display, switch the cuvettes. Insert the cuvette with the dark liquid into the container and press the button again.
• The displayed value should be approximately between 380 and 420 ppm at 25 °C.
