Question 1

What water-treatment media can M19 instruments test?

Accepted Answer

RO, nanofiltration, and ultrafiltration membranes, microfiltration, and cartridge media, activated carbon and sorbents — for pore size, water flux, permeability, filtration efficiency and density/porosity.

Question 2

Which standards do the instruments follow?

Accepted Answer

ASTM F316, ASTM D6767, ISO 7231:2023, ASTM D737-18, ISO 9237, ISO 15105-1, ASTM D1434, ASTM B923-10 and more — listed per product.

Question 3

Can the analyzer resolve nanoscale RO/NF membrane pores?

Accepted Answer

Yes. High-pressure capillary-flow porometry resolves nanoscale pores well beyond the range of standard instruments, non-destructively.

Question 4

How is water flux / permeability measured?

Accepted Answer

A constant pressure differential is held across the specimen while liquid flow is measured precisely, giving reproducible flux/permeability values for QA/QC and design.

Question 5

Do you provide local support in India?

Accepted Answer

Yes. Domestic manufacturing gives faster service, ready spares, lower cost and a 2-year extended warranty.
