PHOTOMETERS

PHOTOMETERS, CHLORINE DUO
Portable, hand held instrument that is a simple button layout, with robust waterproof
design (as defined in IP 68, 1 hour at 0.1 meter) and large backlit display that makes
it easy to use and ideal for testing in the field, laboratory or plant room.
It uses high quality interference filters with long-life LEDs as a light source without
any moving parts in a transparency sample chamber. The units supply accurate,
reproducible results very quickly. Other major advantages include ease of operation,
ergonomic design, compact dimensions and safe handling. Features include scroll
memory function which saves the last used range and One Time Zero (OTZ) function,
making it unnecessary to zero the instrument between each test allowing multiple
tests to be performed using the same blank/zero sample until a new parameter is
selected.
The calibration and software-based adjustment options mean that it is also suitable
for use as a testing instrument. The tests are conducted using Lovibond tablet
reagents (with C73-3000) with long-term stability and a guaranteed minimum 5 or
10 year shelf life or VARIO powder reagents (with C73-3005). These are available
separately.
Supplied complete in carrying case with 4 micro batteries (AAA), 3 round vials (glass)
with lids, tablet reagents or powder reagents, guarantee sheet, certificate of
compliance and instruction manual.
