Turbidity Systems
Planet Ocean are pleased to represent the ANALITE range of turbidity instrumentation manufactured by McVan Instruments of Australia. Planet Ocean service the UK and Western European markets.
ANALITE Turbidity Instruments
Analite stands for innovative and practical turbidity and surface tension measuring instruments. Over the last few years Analite has become leaders in the field of turbidity measurement as well as simple but accurate laboratory measurement of fluid surface tension.
Lens wiping technology:
All Analite probes are available with lens wiping technology to ensure that the optical head is free from contamination during measurement.
Previously all wiped probes were fitted with foam pad wipers. Since the beginning of 2008, probes have been supplied with new Silicone pads, providing longer life and less opportunity for damage to the lens by grit.
Analog output OEM:
Series 9000 -
With lens wiping technology.
ANALITE 9000 series probes are enhanced versions of the successful 190 & 195 devices; they offer better performance and greater ease of deployment, whilst maintaining the same mechanical package. Depth rating is now certified to 100m for the Stainless steel version (shown left) and 50m for the corrosion resistant composite plastic version. Please specify at time of order.
Probes are
available with a choice of cable gland (shown) or connector.
Cable length is specified at time of order.
The 9000 uses nephelometric 90o optical retro-scatter
technology to ISO 7027 to measure turbidity levels up to 3,000 NTU.
Standard ranges are 100, 400 and 1000 NTU with up to 3000 NTU to special
order. A newly implemented
differential measurement technique with sample and hold provides enhanced
performance at low turbidity levels, and extremely low zero drift. All probes
use a unique modulation technique that ensures almost total rejection of ambient
light conditions
The 9000 turbidity probe is designed for applications that will not allow
bio fouling to build up such as short monitoring deployment or placement in fast
and cold running water. The 9500 however, with its integral lens wiper assembly,
is designed where bio-fouling or sedimentation buildup is likely. The wiper is
under operator/logger control.
Standard output is now +/- 2.5v DC (0 NTU = -2.5v) with 0 – 1V and 0 – 2.5 volts as an option, this makes interface to a wider range of data loggers simpler. BE SURE TO SPECIFY 0 - 1V
The predecessor 190/195 system is now the standard field instrument used by the UK Institute of Hydrology, NERC, USGS and CSRIO.
The ANALITE NEP180 turbidity probe is designed for applications where high turbidity is the norm and it uses our retro-scatter technology for ranges up to 30,000NTU
Digital (RS-232 / SDI-12) output OEM:
Series 390/395 - With lens wiping technology.
Turbidity probes using 90° fibre-optic technology intended for logging deployments. These probes, incorporate digital outputs with RS-232 and/or SDI-12. The 390 series offers a host of advance signal processing and control features, and one instrument offers user selectable ranges covering 0 - 40, 100, 400 and 1000 NTU. A wiper version (395) is available.
Depth rating is now certified to 100m for the Stainless steel version (shown left) and 50m for the corrosion resistant composite plastic version. Please specify at time of order.
The 390 series has been enhanced to include the 391 & 396 options. These bring together all of the features of the digital 390/395 with the simplicity of the analogue 190/195. The SDI-12 interface gives way to a DUAL analogue output. Select from either 0 - 1 volt DC, 0 - 2.5 volt DC, 4 - 20 mA or 0 - 20mA. All functionality is user selectable via the RS-232 interface.

Direct reading:
Series 160 - State-of-the-art portable microprocessor based turbidity meter with built-in logging ability using either 90° or retro-scatter fibre-optic probe technology.
The 160 system is now standard in service equipment with the USGS and CSRIO.
Internal data logging with temperature:
Series 495 With
lens wiping technology. Internal recording turbidity probes using 90°
fibre-optic
technology intended for logging deployments. These probes, are manufactured
within a self contained stainless steel pressure case and can be deployed to
record turbidity and temperature at remote locations for extended periods.
