Features of ATR-ST Automatic
Refractometers
Introduction to automatic
refractometers |
|
Refractometry and
Concentration The Schmidt and Haensch range of automatic
Refractometers supplied by Topac measure both the refractive index and the temperature of the
sample in order to evaluate the Brix value. They read out both the actual
refractive index and the actual sample temperature, but they automatically
correct the Brix value to what it would be at 20 degs C. regardless of the
actual sample temperature. ( In the range 10 - 40 C) The new ATR-ST is an automatic critical-angle refractometer for the measurement of liquid media indepent of their viscosity, colour and transparency to be used in the quality control of productions and laboratories. The ATR-ST, equipped with a detachable funnel, replaces the ATR E and -C and offers an additional range of possibilities. The newly designed casing offers more space for a bigger LCD display and a splash proofed foil keyboard. Batch numbers can be entered directly and also simple forms may be created and printed out. 4 special scales, one of them being programmed as Bx scale and one of them as a grease scale according to Leithe by the factory, allow various applications in production and laboratory. The software of the ATR-ST, designed close to the practice makes it possible to take the mean value and to determine standard derivation and adjustable measuring delay for special measurements in dependence of the temperature. All functions may also be controlled via PC using the remote control program.
