Analysers and UPS hardware at the manufacturer's ex-works price — our margin comes solely from the export tax rebate. Batteries are bought locally (transport rule); this sheet gives the Ah and the tropical 2-year replacement note behind that purchase.

How do I size a UPS for a wastewater online-monitoring station?
Add the VA of all analysers and instruments, then size the battery for the hold-up time. The calculator returns UPS VA rating and battery Ah from the analysers you tick and the hold-up time you set.
How do I size battery Ah with lead-acid DoD, C-rate and tropical correction?
Usable Ah = rated Ah x depth of discharge (DoD); C-rate and tropical-temperature derating cut usable capacity. The calculator applies lead-acid DoD, C-rate, and tropical temperature correction to the battery Ah.
What does an online-monitoring station UPS and battery cost to run?
The calculator returns the station power bill from UPS VA, battery, and duty, so you see the exact running cost before specifying the equipment.
