Features

• The new optimized membrane glass guarantees quick measurement even at low temperatures
• The silver ion-free reference electrolyte prevents interference by precipitated silver (self-cleaning)
• SenTix^® PLUS electrodes with Gel electrolyte and a plastic body are robust and shockproof.
• The membrane glass is optimally safe-guarded by a protective shield.
• SenTix^® H and HW electrodes: electrolyte flow speed can be adjusted for optimal use.
• The easy to use fill-hole cover prevents electrolyte from leaking out during storage.
• SenTix^® PLUS electrodes with liquid electrolyte – the capillary effect of the platinum wire guarantees constant outflow and prevents contamination by precipitates or dirt even during changes in temperature; with new membrane glass for an even quicker response.
• The SenTix^® HWD also measures temperature and it comes with a fixed 1 m cable.

SenTix^® HWD – proven and tested sea water pH electrode system with build-in temperature probe from German WTW is easier to use and offers more quality and precision.

Features

• Highest degree of precision and linearity by optimized cell geometry
• Extremely large measuring range with just one cell
• Long-term cell constant stability with high-quality abrasion-resistant graphite electrodes
• With built-in temperature sensor as standard
• Smallest immersion depth possible
• No measuring errors even with very dirty electrode – contact resistance on the electrode surface is automatically compensated
• No measuring errors from cable influences
• No measuring errors from primary or secondary polarization effects
• No measuring errors due to contact with side walls or base of measuring vessels
• Robust, unbreakable epoxy body

The TetraCon^® 325 condictivity probe is the result of WTWs commitment to quality and sets a new standard for professional conductivity measurements. In comparison with conventional measuring cells with 2 electrodes, the TetraCon^® 325 conductivity probe offers numerous technical advantages.
