Focustronic Reagent Kit – Calcium (50,50,200ml)

New Focustronic ReagentFocustronic Reagents are made for the Mastertronic Essentials testing Machine. These are very High-Resolution Reagents with consistent readings on the Essentials! (Not Compatible with Mastertronic yet) But Focustronic has also not restricted the MTE to only their reagents you can use off the self reagents as well, as a contingency so no need to stop testing. div img attachment-1536×1536 size-1536x1536src=https://focustronic.com/wp-content/uploads/2025/07/Screenshot-2025-07-22-at-11.53.12-am-1-1536×321.png" sizes=auto, (max-width: 1536px) 100vw, 1536pxsrcset=https://focustronic.com/wp-content/uploads/2025/07/Screenshot-2025-07-22-at-11.53.12-am-1-1536×321.png 1536w, https://focustronic.com/wp-content/uploads/2025/07/Screenshot-2025-07-22-at-11.53.12-am-1-300×63.png 300w, https://focustronic.com/wp-content/uploads/2025/07/Screenshot-2025-07-22-at-11.53.12-am-1-1024×214.png 1024w, https://focustronic.com/wp-content/uploads/2025/07/Screenshot-2025-07-22-at-11.53.12-am-1-768×160.png 768w, https://focustronic.com/wp-content/uploads/2025/07/Screenshot-2025-07-22-at-11.53.12-am-1.png 1696walt=width=833height=174loading=lazy Approx Tests per bottle.
