Portable Multiparameter Meters Product Description

The robust and user friendly WTW ProfiLine Multi 1970i Portable Multiparameter Meters are both hose down-proof (IP 66) and submersible (IP 67).  With its recorder output, real-time clock and 500 data file data logger standard, the rugged Portable Multiparameter Meters conform to all GLP requirements.  Designed for multitasking to make your job quicker and easier, the Multi 1970i Portable Multiparameter Meter allows the simultaneous connection of pH, conductivity and oxygen sensors.  An intuitive user interface makes it easy for the portable multiparameter meter to measure a parameter and store in memory.  Field ready, the Multi 1970i Portable Multiparameter Meters feature powerful NiMH rechargeable batteries (up to 600 hours or operation per charge) and is equipped with a carrying/support handle and carrying strap as standard.

Deep Water Measurement of Oxygen, pH and Conductivity
The Multi 1970i Portable Multiparameter Meters have a convenient built-in preamplifier to work with the WTW deep water sensors for single-parameter operation at depths down to 330 ft (100 m).  Up to three deep water sensors can be simultaneously connected to the Portable Multiparameter Meters using the adapter ADA/TA 197 pH.  The WTW deep water sensor assemblies are pressure resistant up to 145 psi (10 bar), have an integrated temperature measurement, steel armoring, a screw-on protective hood and are available with up to 330 ft (100 m) of cable with a waterproof plug (IP 67).  These compact sensors will even fit small monitoring wells down to 2 (50 mm).  Choose one or all three: TA 197 Oxi oxygen probe, TA 197 pH pH probe or TA 197 LF 4-electrode conductivity probe.
