WTW Cond 315i, Cond 330i, Cond 340i İletkenlik Ölçerler

Cond 315i, Cond 330i, Cond 340i

  • Robust, shockproof, waterproof
  • Up to 1500 hours of continous operation
  • 4-electrode principle allows a wide range of applications

Useable anywhere, WTW handheld instruments are robust, easy to operate and provide assured accurate readings. From the monitoring of on-line process systems to field studies, WTW's handled Conductivity meters meet all your measurement need.

WTW handheld Conductivity meters are available in three versions :

Cond 315i

The simple conductivity meter for  meeting higher demands. With only 5 keys for error-free measurements with parallel temperature measurement, automatic temperature compensation, 4-electrode measuring technology.

Cond 330i

Robust and waterproof handheld conductivity meter for battery operation ; with parallel temperature display, integrated datalogger, GLP supporting functions automatic and manual temperature compensation with linear temperature function and non-linear function for ultrapure water and natural waters according  to DIN 38 404 and EN 27 888. The temperature compensation can be swicthed off ; either 68 oF or 77 oF (20 oC or 25 oC) can be selected as the reference temperature.

Cond 340i

As Cond 330i, but with additional analog and digital RS 232 output and optional power supply is available.
