The TRH444 is a compact turbidity analysis
instrument designed for precision measurement of
turbidity. The meter is equipped with an advanced
microprocessor that results in long-term stability
over a wide range of operational conditions.
With its low level precision and accuracy, the
TRH444 meets “GLP” standards for water and
wastewater analysis. The TRH444 can be used
to detect turbidity in three selectable ranges
(0.01 to 10, 0.1 to 100 and 1 to 1000 NTU units)
for turbidity. Other features on this all-in-one meter
include automatic range selection, signal averaging,
data logging up to 99 readings, RS232 interface
port (for PC or printer connection) and language
selection (English, Spanish or Portuguese). With
it’s self guided programming menu the TRH444 is
an ideal choice for regulatory monitoring, process
water testing, and environmental water analysis in
the field or laboratory.
