The MTOL+ process turbidimeter allows for the measurement of the turbidity of process water on-line. The MTOL+ works by nephelometery; which means it measures reflected light at 90° incident to the light beam. The white light MTOL+ (Model #28053) has been designed to meet the design criteria specified by the US EPA 180.1 on turbidity measurement.
The infrared MTOL+ (Model #28052) was designed to meet the design criteria specified in ISO 7027 and DIN 27027 for the measurement of the turbidity of a sample. Both models have long life lamps. All models have ultrasonic cleaning. Refer to section 5.5 for more information. A pressure regulator on the incoming line is a standard on all MTOL+ instruments and will reduce pressures up to 7 bar (101.5 PSI) down to 1.03 bar (15 PSI). The MTOL+ instruments are fully equipped with isolated 4-20mA, Modbus, two alarms and ultrasonic cleaning. The only option is a flow alarm which must be factory installed.
