JCB33400-02 Diesel Total Contaminant Content Analyzer
Category:
This instrument is used to determine the total contaminant content in diesel fuel and pure biodiesel (BD100) with a volume fraction of middle‑distillate oils and fatty acid methyl esters not exceeding 30%, as specified by the relevant standards. It is also suitable for samples with a kinematic viscosity of no more than 8 mm²/s at 20°C or no more than 5 mm²/s at 40°C, and for samples containing 12 mg/kg to 30 mg/kg of total contaminants, with precision specifications provided. The instrument can further be applied to samples whose total contaminant levels fall outside this range, though its precision for such cases is not defined. It is the preferred choice for refineries and testing laboratories seeking to measure the total contaminant content in diesel fuel. The instrument features a long service life, low noise, minimal vibration, compact dimensions, ease of maintenance, an attractive appearance, and simple operation.

Product Details
This instrument is used to determine the total contaminant content in diesel fuel with a volume fraction of middle‑distillate oils and fatty acid methyl esters not exceeding 30%, as specified by the standard, as well as in pure fatty acid methyl ester (BD100). It is also suitable for samples with a kinematic viscosity of no more than 8 mm²/s at 20°C or no more than 5 mm²/s at 40°C, and for samples with a total contaminant content ranging from 12 mg/kg to 30 mg/kg; precision requirements are stipulated for these conditions. The instrument may also be applied to samples whose total contaminant levels fall outside this range, though no precision specifications are provided for such cases. It is the preferred choice for refineries and testing laboratories seeking to measure the total contaminant content in diesel fuel. The instrument features a long service life, low noise, minimal vibration, compact dimensions, easy maintenance, an attractive appearance, and simple operation.
