Designed with protection against excessive exposure to moisture
in mind, the DC1200 Series colorimeters deliver trouble-free
performance in the field and lab. A microprocessor enables the
factory-programmed calibrations to optimally match non-linear
curves. Simply insert the blank sample and press the zero key.
No more dialing in the zero. “Up” and “down” arrows enable easy
calibrations to a standard for compliance monitoring a flip-top lid
over the sample chamber eliminates any stray light, especially in
the field, and prevents misplacing separate light caps. The large
89 mm (3
1
/
2") digital display presents measurements in actual ppm
concentration and indicates low battery warnings. An RS-232 port
is provided to interface with a datalogger or computer. The
DC1200 Chlorine Colorimeter Kit uses unit-dose DPD tablets
or DPD liquid reagents.
