Refractometers
-
A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The refractive index of a certain sample varies for nearly all materials for different wavelengths. This dispersion relation is characteristic for every material. Temperature has a very important influence on the refractive index measurement. Therefore, the temperature of the prism & the temperature of the sample have to be controlled with high precision.

AdBlue & Urea Refractometer
RHA-503ABATC
-
Fuzhou Zhongtuo Optoelectronic Co.,Ltd
The AdBlue refractometer RHA-503ABATC is a new hand held refractometer developed to address the growing need to check the urea concentration in AdBlue.Escalating urea prices have driven the cost of operating an SCR higher than ever before. Regretfully this has led to a new wave of problems where supplies of diluted AdBlue have found their way in to the market.Often rebranded ‘Automotive urea solution’ to eliminate the risk of prosecution by trading standards (as a mix of less than 31.8% urea cannot be labelled AdBlue). Victims of this weaker concentration may not be able to seek compensation under the Trades Description Act.
