Application

For monitoring absence

of chlorine in reverse

osmosis systems1.)

(zero-chlorine)

For monitoring free chlo-

rine at fluctuating pH in

eg. drinking water

For monitoring free

chlorine at constant pH

in eg. swimming pool

For monitoring total

chlorine at fluctuating

pH in eg. swimming

pool, drinking water, sea

water, brine (15 % NaCl)

Compatibility
