Description

The HF Scientific MTOL+ Online Turbidimeter has been specifically designed for measuring the NTU of filtered water, re-use water, raw water and many industrial applications. The MTOL+ features built-in ultrasonic auto-cleaning and data logging as well as easy set-up, maintenance, and calibration. Calibration is completed using ProCal™ EPA-approved NTU calibration standards. The continuous monitoring NTU system is an online model with power supply, display, user interface and sensor. It is not necessary to purchase a separate module for display or power supply. The turbidimeter is Modbus compatible and has a 4-20 mA output.

The process turbidimeter lamp source and detector does not come in contact with the sample, eliminating false low readings. The MTOL+ uses menu driven software and has an ABS enclosure. The online turbidimeter has data logging features, stores the latest date/time of calibration, and has user-selectable ranges of 0 to 10 NTU, 0 to 100 NTU (factory default) or 0 to 1000 NTU.

The HF Scientific MTOL+ Online Turbidimeter accuracy is 2% of reading or ±0.02, whichever is greater, from 0 to 40 NTU; and 5% of reading or ±0.02, whichever is greater, from 40-1000 NTU. Resolution is 0.001 NTU (user selectable). The sensor utilizes a rotational flow-through assembly with a 30ml measuring cuvette. The specially designed flow-head bubble-rejection system reduces the need for a bubble trap and provides a faster response time. The sample stream will remain under pressure, ensuring it will not be exposed to open atmosphere, which can cause precipitants in some circumstances. Precipitation of oxidized sample constituents can result in false NTU readings. The sensor allows grab-samples to be measured without the need to stop sample flow to the flow head.

The turbidimeter meets all requirements specified by the US EPA Method 180.1 (White Light Model), ISO 7027 (Infrared Model) and Standard Methods 2130B. White light is recommended for use in turbidimeters reporting results under US EPA 180.1 (US standard) jurisdiction. The white light is Tungsten filament, krypton gas filled, and has a life expectancy of 5 to 7 years. Infrared light is recommended for use in turbidimeters reporting results under ISO 7027 (European standard) jurisdiction. Infrared light is also recommended for some waste water final effluent and industrial applications where color is present in the sample stream.

Calibration and standardization is accomplished using small volumes (30ml) of reusable primary standards. Primary Standards are reusable for multiple online turbidimeters. Calibration procedures can be completed without disrupting the sample flow. Details of calibration (date and time of last successful calibration) are stored on the analyzer.

The MTOL+ is compatible with the M100+ laboratory turbidimeter which offers a color touchscreen display and sample data logging for multiple sample ID's. The M100+ also stores calibration NTU values and the date/time of calibration. The two units share calibration standards eliminating the need for different calibration standards between laboratory and process NTU. MTOL+ Ranges include 0 to 10, 0 to 100, and 0 to 1000 NTU.
