Merck Formaldehyde Test Strips

No. Merck rates these strips for freshwater samples only – a marine or brackish system needs a seawater-validated formaldehyde method.

The colour-chart step size is not published by Merck, so treat each reading as a band rather than an exact figure.

No. You dip the strip and compare it against the printed colour chart – no meter, reagents or laboratory required.

Merck does not publish a shelf life for this pack on our source data – check the expiry date printed on the tube when it arrives.
