used it for metering reverse osmosis water

Using mostly to monitor flow rate haven’t figured out how the change from litres to gallons.

It kinda works but has a terrible "manual" which tells you very little. There is some kind of procedure to calibrate it that makes no sense due to language-transalation issues. But the biggest flaw is that you simly cannot reset the total-counter. The "manual" will tell you to hold down one of the two buttons for 5 seconds to do this but that does not work and yields nothing. You are buying a unit that will count up forever and have no way to reset it. You can reset the "trip" secondary counter but this is easily pushed and you may lose your log inadvertantly.

Not accurate and susceptible to moisture intrusion.

Ce produit avait une odeur forte d’huile d’usinage. Nous avons du le laver et le faire tremper plusieurs jours pour enrayer cette mauvaise odeur. Il fonctionne bien et il est facile d’utilisation.
