Water Testing

PHOTOMETER, MOBILE, INFRA-RED
Hand-held, portable device in a modern design with waterproof housing and with
the analytical features of laboratory photometers.
All-important water analysis parameters from A to Z (Aluminium to Zinc) are covered
by this device. Combined with the high precision of reagents, a reliable and quick
analysis of water samples is guaranteed. Reagent tablets, powder reagents, liquid
reagents, or cuvette tests are used depending on the method.
Six long-lasting LEDs serving as a light source in combination with interference filters
guarantee the highest precision. The device is designed without moving optical parts
and thus has a maintenance-free measuring unit. Up to 1,000 data records can be
stored and more than 35 user-specific methods possible.
The photometer uses the classic infrared interface with which data can be transferred
by means of the IRiM module (C25­0030) to the PC or laptop.
The instrument has a factory calibration, which is related to international standards,
which are not N.I.S.T traceable. The instrument may be calibrated by the user in a
“user calibration mode” with N.I.S.T traceable standards.
Test methods are regularly updated to suit market requirements. You can find
software updates for new methods and additional languages on our website under
Support.
Polynomials
With the help of an external mathematical program, the corresponding polynomial
is created from data pairs (concentration/absorption).
A known polynomial may also be used. 25 order polynomials (y = A+Bx+Cx2 +Dx3
+EX4 + FX5) can be stored together with user-specific parameters such as
wavelength, measuring range, unit and number of decimals.
Concentration
This function can be used to measure 2 to 14 known standards. On the basis of the
concentrations/absorption pairs obtained, the photometer will calculate a linear
interpolation between the measured points. Up to 10 methods can be stored for
further sample measurements.
