TURBIDIMETERS
Direct-reading, 3 Range, USEPA Approved Design
Orbeco-Hellige Model 966 Portable and Model 965-10A Bench-top Turbidimeters
quickly and precisely measure the clarity or cloudiness of any type of
fluid. Both meet the official specifications of USEPA, ASTM, Standard
Methods of APHA, AWWA, WEF and other world-recognized authorities. True
nephelometers, both test at the officially mandated 90 degree angle between
photo-detector and incident light beam. Direct-reading displays give results
in NTU's (Nephelometric Turbidity Units) over the full span of turbidity
in 3 ranges. Both meet design requirements of USEPA Method 180.1
and are ideal for NPDES and NPDWR compliance reporting. Also can be used
to test water for Barium, Sulfate, Nitrate, Silver and Chloride using
turbidimetric chemical analysis.

USEPA Approved Calibration Standard
The supplied 40NTU USEPA
approved styrene divinylbenzene
copolymer standard easily confirms calibration validity of all 3 ranges
as required by the USEPA. Standard is highly accurate, reproducible, safe,
non-toxic and non-carcinogenic. No volumetric dilutions are ever required.
Standard has a guaranteed shelf life of one year.
|
Factory Standardized for all 3 Ranges
The factory preset locking knobs of both turbidimeters need never be overridden until USEPA confirmation is scheduled. Operation
is simplicity itself. Just select the range and insert the sample tube.
The test result is then easily read on the digital display.

Flow-Through Cell for Continuous Reading
of Pumped or Flowing Samples.
Flow-through cell has a unique "self-cleaning"
design whereby incoming fluid impinges forcefully against the interior
cell wall and swirls for continuous scouring action. Installed in seconds.
No need to disconnect flow for calibration check. Just lift out the
cell with flow tubes intact and substitute the calibration cell. Flow
rate is 1-2 liters/minute, 0-5 psi. For use with bench-top turbidimeter
model 965-10AR and portable turbidimeter mosels 966-R1 or R2, all having
recorder outputs.
