Tenders are invited for Nephelometer
. Details as per attached documents.
Afterward, clean supernatant liquid was drawn from a depth of 1.0 cm and its turbidity in nephelometric turbidity unit (NTU) was measured using a digital nephelometer
model, Bellstone Hitech International).
Technician tasks include nephelometer
calibration gas checks (performed with C[O.sub.2] and filtered air) to verify instrument calibration (Anderson and Ogren 1998), impactor cleaning, filter changes for the light absorption instruments, and replenishing the operating fluid for number concentration instruments.
IgG subclass measurements were performed by BSIN using the Siemens BNII Nephelometer
and, in a subset, also by SIN using the Siemens BN ProSpec Nephelometer
The agency reads particulate levels with a device called a nephelometer
, which gauges the dimming effect of pollution on sunlight.
The readings from a nephelometer
are at best an estimate, and from comparison studies of factory-calibrated nephelometers
with co-located gravimetric instruments, usually an overestimate of mass.
The turbidity of the sample is analyzed by using Nephlo turbidity meter.set the Nephelometer
to '0' and '100' readings using double distilled water '100' NTU standard.
Concentrations of hsCRP were measured using a nephelometer
(Model BN2, Japan).
Last summer, Dalhousie University's Graydon Snider was on the roof of a half-built office building in Bangladesh setting up a nephelometer
--an air sampler device--to measure the concentration of suspended particulates in the thick, grimy air.

One of the important devices for a winery laboratory is a nephelometer
. This device measures turbidity of a liquid.
Test and control strains were seeded in Mueller-Hinton agar supplemented with 0.5% defibrinated sheep blood and 0.1% esculin (Soriano, Fernandez Roblas, Calvo, & Garcia Calvo, 1998), previously adjusted to the 0.5 McFarland nephelometer
