Used Lab Equipment

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).

Description:

The Corning Model 311 is a multi-range, water resistant, Conductivity Meter with automatic temperature compensation. The sensors in the meter’s probe utilize the latest technology in conductivity measurement. The four-ring potentiometric method incorporated into the probe has been proven to provide higher accuracy than the more common amperometric method. The Model 311 has a range of 0 to 199,900 µS/cm and can be used in any sample from treated water to brine. The temperature of all conductivity measurements are automatically compensated for by the meter’s ATC circuitry. The probe is easily detached and can be changed without having to be returned to the factory. The meter is constructed with a water-resistant, rugged ABS plastic housing which allows the versatility of both laboratory and field use. Other features include a Low Battery Indicator warning which prevents erroneous readings due to low battery voltage.
