Description:

The 2100AN laboratory turbidimeter measures turbidity in NTUs (nephelometric turbidity units), NEPs (nephelos) and EBCs (European Brewing Convention units). NEPs and EBCs are calculated using the conversion factors of 6.7 nephelos per 1.0 NTU and 0.245 EBCs per 1.0 NTU. The 2100AN turbidimeter also measures absorbance, transmittance and color (APHA Pt-Co Method). The turbidimeter has a built-in printer and an RS232 output for connection to a printer, data logger or computer and a recorder output. The turbidimeter contains a real-time clock with battery. The clock provides a time-date stamp on all data transmitted to the built-in printer or to external devices by way of the RS232 interface (i.e., measurements and calibration records).
