ML-54

APPLICATION

ML-54 sludge concentration meter.It is a portable instrument to on-site measure activated sludge concentration of sewage,waste water,purifier and wastewater treatment system,and determine sludge concentration of sludge zone in settling basin.

FEATURES

l Battery powered,portable,easy to operate;

l Can be connected to printer;

l Be able to duly determine concentration and water depth;

l Automatic return-to-zero calibration function;

l Several calculating method;

l Alarm monitoring;

l Low battery warning;

l Automatically turn off after no working for 10mins,the turn-off time can be set by users.

KEY SPECIFICATION
