pH 315i, pH 330i, pH 340i Robust Waterproof (IP 67) Large silicone keys WTW handheld pH meters are optimized for use on-site and field use, but can also be used in the laboratory. In particular the pH 340i, with its optional line power supply and serial interface, is suitable for applications in which precise measurements are required both in the laboratory and the field. WTW handheld pH meters are available in three ve…

All WTW Technical buffers are certified accurate and are NIST/DIN traceable   The new buffer bottles from WTW: easy to dispense easy to use reliable calibration

WTW offers a wide range of Ion-Selective Electrodes and instruments. Series 500 electrodes are used in combination with a separate reference electrode. And now WTW introduces our Series 800 quality combination ISE’s! These precise electrodes combine a reference and ion selective electrode in one unit. The convenience of this design allows for ease of use even in small sample volumes.

The pH/mV and ionmeter pH/ION 340i offers the highest degree of flexibility possible. For pH measurements the instrument can be calibrated manually or automatically and offers simultaneous display of pH and temperature. For measurements with ion-selective electrodes the pH/lON 340i offers concentration display in mg/l. Direct display in mV to ±999.9 mV in 0.1 mV steps; and to ±1999 mV in 1 mV steps. Of course, even in these…
