Turbidimeter Model 850
The Model 850 is an innovative turbidimeter which utilizes an insertion-type sensor. A submersible sensor is available for open channel applications. Since the sensor can be inserted in any size pipe, costly by-pass systems are not required. The design eliminates the effects of fluid color. In-situ measurements provide instantaneous accurate readings and a choice of isolated linear outputs is supplied as standard. A 4-position calibrated range dial allows for the selection of four NTU ranges.
The Model 850 Turbidimeter uses a pre-focused incandescent lamp to direct
a beam of light through the process fluid. Particulate matter in the fluid
scatters light in proportion to particulate concentration. The scattered light
is detected by a silicon detector which generates a current signal proportional
to the particulate concentration. The electronic signal converter amplifies and
scales the current signal to provide a linear readout on a digital meter plus
an isolated output signal.
Features include:
- Wide dynamic range
- In-line measurements assure maximum accuracy
- Hot-tap installation permits uninterrupted flow
- Linear isolated output
- Optional alarms, battery power
- Use in any size pipe
- High accuracy and reliability
- Insensitive to visible colors, flow, temperature & pressure
- 4-position range dial (0-2NTU, 0-20NTU, 0-200NTU, 0-2000NTU)
