PH Sensor Systems

Sentron, Inc.our pH meters and ten pH probes based on rugged ISFET (Ion Sensitive Field Effect Transistor) sensor technology has been released. The pH meters are designed for ease-of-use and feature an interactive graphics LCD display with on-board Help and Auto-Read functions. All meters constantly monitor and display probe status and an estimation of its remaining life. The advanced meters have real-time clocks for time/date stamping, calibration alerts, and high/low pH alarms.

TITAN Benchtop pH meters operate on AC or battery power and features programmable user alarms and datalogging. ARGUS portable meters are rugged, waterproof and operate on a long-life rechargeable battery. Each meter is available in simple or advanced versions and is supported by a variety of probes covering most applications.

The portable model uses an inductive (contact-less) battery charging system and IR data transfer eliminating the need for battery replacement or open contact points. This unique design ensures a completely watertight (IP67) rating.

Three new series of ISFET probes include the Red-Line general purpose series for routine applications, the Hot-Line series for testing to 105°C and in aggressive samples, and the Stream-Line series that are temperature and chemically resistant and employ a flow-type reference junction to maximize performance in difficult samples. All of the probes use a large-surface area reference junction of porous PTFE that is said to improve performance in all applications.
