The Viscometer: we have a range of on-line viscosity analysers for various applications. They corre-
late with the corresponding ASTM laboratory standard measurements. As well as measuring New-
tonian fluids we also have special capillaries that enable us to handle non-Newtonian samples.
Models are also available to handle high pour point streams.
Option: Viscosity index (dual bath) - continuous viscosity measurements at dual temperatures (typ-
ically 40°c & 100°c)
Colour and Opacity Monitor: The Hallikainen colour analyser can measure in accordance with ASTM,
Saybolt and other scales. An opacity version is also available.
Cloud Point Analyser: The cloud point refers to a fuel’s temperature as it begins to thicken and
“cloud” as the temperature drops due to some of the heavier “waxy” components beginning to
precipitate out.
The i-Cloud utilizes a measuring cell which minimizes the effects of any dissolved water in the
stream and also features a touch-screen intuitive colour display. As with all our on-line physical
property analysers, it correlates well with the corresponding ASTM laboratory standard measure-
ments.
Viscosity
Analyser
The VISCO-VP is a new generation of in-line viscosity meter. The VISCO-VP is a torque -oscillating vis-
cosity meter, which measures the drag of a fluid at the surface of the sensor. The sensor oscillates at
its resonance frequency, and the amplitude of the vibration is muted as the viscosity increases. The
viscosity can be calculated out of the energy required to keep the amplitude constant.
Depending on the process fluid and application, there are various models VISCO-VP for the required
measurement range and accuracy.
We also have the VISCO-FT: this is a flow-through model, in which the process fluid flows through a
straight tube with no bend restrictions The sensor can be produced in a variety of materials such as
polycoated for aggressive fluids. Advantages: proven in many applications and installations, no moving
parts (torque-oscillating), robust, no maintenance required, fast and accurate measurement, suitable
for low and very high viscosity.
Applications: Chemical, petrochemical, pharmaceutical, food industry. Other applications are possible
with fluids such as: acrylic fibres, textile fibres, black liquor, condensed milk, darcon, lycra, gelatine, PET,
resins poly-isobutyls and printing ink.
Process
Refractometer
The in or online refractometer is a process refractometer and measures concentrations based on
the refractive index of an infrared light beam going from a sapphire prism into the process liquid.
The unique optical principle of the refractometers is patented.
The refractometer has a sensitivity of up to one thousendth of a per cent and is highly stable.
An optional continuous ultrasonic cleaning systems prevents any coating of product on the surface
of the measuring prism not adding water, steam or any chemicals into the process liquid.
Advantages: the analyser can measure very low concentration variations at high precisions. The
measurement is not influenced by temperature variations or fixed particles in the process liquid,
by pressure variations, opacity or other interferences. An unique and patented ultrasonic cleaning
system prevents coating of the measuring prism.
Applications: Food and Beverage: measuring soft drinks and juices, beer, applesauce, syrups, al-
cohol-distillation processes, etc. Chemical and Petrochemical: Teflon plunge bath, PVA, ammonia,
cooling- and lubrication liquids, gelatines, urea, DMAC, etc.

measurement
The vapour pressure analyser utilize the jet or-
ifice measuring principle which enables a con-
tinuous measurement and which correlates
well with the corresponding ASTM laboratory
standard measurements.
The Hone 4400 continuous flash point analys-
er is very well field proven and uses a univer-
sally accepted catalytic detector. Correlates to
ASTM D93 or D56 test methods.
Distillation: the new microprocessor con-
trolled D86 Boilar utilizes the latest designs
to incorporate ultrasonic level detection, au-
tomatic barometric compensation and a multi
stream capability which can further meet your
continuous boiling point needs.
The only solution for low ppm/ppb H2S
meassurements. The principle of operation is
as follows. A reel of paper tape impregnated
with lead acetate is exposed to the gaseous
process sample in the sample chamber. Hy-
drogen sulphide (H2S) in the process sam-
ple reacts with the lead acetate, after acidifi-
cation, to form lead sulphide (PbS), a brown
compound that stains the tape.
The higher the concentration of H2S the dark-
er the stain. A focused LED and single photo
detector system continuously measures the
darkening stain and the analyser reports this
as a 4-20mA output of the concentration of
H2S.
Applications: gas, liquids & oil

Innovation in Process Monitoring & Control
Standard FTIR analytical instruments are highly sensitive to vibration and ambient temperature—
making them a challenge to use outside or on the manufacturing floor. Keit offers an innovative
solution for continuous monitoring of your processes in real-time over a variety of industrial applica-
tions – from detecting the quantity of water in glycol at a petro-chemical plant to measuring sugars
and alcohol in a fermentation vat.
FTIR for Manufacturing Applications
It opens up new horizons for when and where spectroscopy can be applied.
Fourier Transfer Infrared (FTIR) spectroscopy is a well-established analytical technique in the la-
boratory, but conventional instruments are bulky and fragile: susceptible to vibration, temperature
changes, and requiring flexible, lossy interconnects to the reaction vessel making the use of them
in the manufacturing floor impractical.
Unlike standard systems, Keit uses a novel optical design with no moving parts. It is impervious
to vibration, weather, and rough operating environments. The dependable IRmadillo™ FTIR spectro-
meter performs with no remote sampling or long fibre-optic cables making it ideal for manufactur-
ing environments for process monitoring and control.
The IRmadillo™ FTIR spectrometer tells production and chemical engineers about their processes
at the time of reaction by being mounted directly onto their production equipment rather than
conventional analysis techniques that requires continual sampling and analysis in a remote stable
environment.
The application of FTIR spectroscopy can be successfully used across a variety of manufacturing
industries.

CEM/EXM500
These analysers are extractive online gas analysers dedicated to continuous emission monitoring
(CEM). It covers applications like DeNOx systems on power plants, generators, chemical plants,
petro-chemical plants, or biogas reactors.
They are based on UV spectroscopy that brings a higher sensitivity and stability than infra-red
systems and also gives the possibility to measure several gases simultaneously, example: NH3,
SO2, NO.
A high selectivity is achieved by a fast Fourier transform (FFT) on the absorbance spectrum for all
the gases having a periodic structure like NH3, SO2, CS2 and others.
All the internal gas circuit is heated at 190°C to admit directly hot and humid combustion gas.
No risk of interference with H2O, CO, CO2 or CH4 as all theses gases have no absorbance
on the UV range.
Applications: Liquified petroleum gas, Gasoline, Napthgas/Kerosene’s, Crude oil, Fuel oil,...
NH3, SO2, NO, NO2, H2S, CS2, NCL3, benzene, toluene, xylene, acetylene
