Automated chemistry analyser systems for UK market
CSP has signed a major partnership agreement with OI Analytical of College Station, Texas, for the supply of its renowned GC detectors and automated chemistry analyser systems to the UK market
The secret to the Polartronic speed is the direct coupling of the analyser to an optical decoder.
This patented system eliminates linearity errors to ensure constant resolution throughout the range, high accuracy and repeatability.
It also removes the need for an operator to reset the polarimeter when beginning a new measurement.

For simultaneous measurement of Pol and BRIX values, all Polartronic models can accept a connection form the S+H DUR-SW refractometer.
Since the polarimeter controls the functions of the refractometer a separate control unit is not required.
The M- and H-series polarimeters are precise, high-resolution instruments built to fulfil the highest demands of quality control and capable of a resolution of 0.001 degrees.
On the multi-wavelength version up to five different measurement wavelengths are selectable via the control panel, a choice of two wavelengths is available on the dual-wavelength manual model, and a single wavelength model is available with a choice of filter in the range 350-900 nm.
The 8-line, 30-character LCD displays levorotatory samples for glucose measurements and optical density up to an absorption level of 99.
percent.
It is also fully programmable to show readings in other concentration units or configured with simple push-buttons for routine analyses.
The N-series polarimeters are easy-to-use instruments for routine analysis and are suitable for many applications, from lab work to saccharimetry.
Designed for applications requiring a 0.01-degree accuracy, they offer outstanding quality and performance at an economical price.
A single line, 16-character LCD displays the absolute angle of rotation in degrees or sugar degrees as well as levorotatory samples for glucose.
Polartronic works with standard and continuous flow tubes, and special tubes are available for temperature measurement and precious samples.
An RS 232 C data interface is fitted as standard on the M- and H-series instruments and on the NH8 model and further serial or analogue interfaces can be fitted on request.
