IN PLEATHER CARRYING CASE. 2.1 U-I0 CONFIGURATION THE U- I0 IS DIVIDED INTO AN INSTRUMENT BODY HAVING A DISPLAY AND OPERATION BUTTONS; AND A SENSOR UNIT WITH FIVE TYPES OF SENSORS A PREAMPLIFIER AND AN ELECTRODE CABLE. THESE TWO UNITS ARE JOINED BY A CONNECTOR SECTION. POLYPHENYLENE ETHER RESIN WHICH POSSESSES SUPERIOR WATERPROOFING AND WEATHER-RESISTANCE PROPERTIES IS USED FOR THE OUTER CASING IN BOTH UNITS. THIS INSTRUMENT USES CARTRIDGE-TYPE SENSORS TO ALLOW EASY REPLACEMENT OF THE SENSORS IF THE PH ELECTRODES OR DISSOLVED OXYGEN (DO) ELECTRODES WEAR OUT OR ARE DAMAGED. THE TURBIDITY SENSOR EMPLOYS A GLASS TUBE PASSING VERTICALLY THROUGH THE SENSOR BODY AS A MEASUREMENT CELL AND AN OPTICAL SYSTEM IS LOCATED AROUND THE MEASUREMENT CELL. THIS ALLOWS THE TAKING OF ACCURATE TURBIDITY MEASUREMENTS EVEN UNDER DIRECT SUNLIGHT. THE ENTIRE SENSOR IS SURROUNDED WITH A CYLINDRICAL-SHAPED GUARD. THIS GUARD PREVENTS THE SENSORS FROM BEING DAMAGED DURING MEASUREMENT AND SERVES AS A STAND WHEN CALIBRATING OR STORING DATA. TO TAKE A MEASUREMENT THE OPERATOR HOLDS THE CABLE AND LOWERS THE SENSOR UNIT DOWN INTO THE WATER TO BE SAMPLED. THE LENGTH OF THE CABLE IS 10 METERS.
