Multi Parameter Instruments, Handhelds, WTW

Multi 350i
Multi-parameter measurement devices in service-proven WTW handheld instrument design, dust-proof and water-proof, for simultaneous measurement, indication and storage of up to 4 parameters: pH/mV/ISE, dissolved oxygen, conductivity and temperature. Menu-controlled with a backlit graphic display. Data logger and memory for more than 1800 entries, GLP-supporting functions, real-time clock, calibrating timer. Bidirectional RS 232 interface. Suitable for connecting a large selection of sensors.
Complete with NiMH rechargeable batteries, wide-band mains power supply and KOM pilot software package for data collection on a PC.

ConOx combined conductivity/oxygen sensor
Simultaneous measurement of dissolved oxygen, conductivity and temperature with just one sensor. The ideal partner in water analysis for the Multi 350i. Automatic salinity correction, modular design. Conductivity module with service-proven 4-pole technology, galvanic oxygen module.

Multi-parameter sensor MPP 350
One sensor, 4 parameters: pH, conductivity, dissolved oxygen, temperature. With cable lengths up to 25 m, excellently suited for parallel field measurements in environmental analysis. The sensor is perfectly tuned to the Multi 350i. Complete with accessories, without pH electrode (must be ordered separately).
