This latest laboratory grade Microprocessor photometer has an
excellent repeatability and is ideal for field measurements.
Chlorine is the most commonly used water disinfectant.
Applications vary from treatment of drinking water and waste-
water to pool and spa sanitization and food processing to steril-
ization.
Martini Instruments has developed the
Mi411, a portable microprocessor
based instrument to measure three
critical parameters to ensure good
water quality: pH, free chlorine and
total chlorine.
This instrument provides greater
resolution, better accuracy and
immediate results.
Mi411 is supplied in a hard carry-
ing case including 2 cuvets,
reagents for 100 tests, wiping tis-
sue and instruction manual.
