High Performance pH ISFET Sensor Systems

The company offers a completely new line of pH meters and probes based on rugged ISFET (Ion Sensitive Field Effect Transistor) sensor technology. Their ten years experience with ISFET pH applications is incorporated in four new pH meters and ten new pH probes.

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 offer a host of sophisticated features including 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 almost every application.

The portable ARGUS_x 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 complete the company's new pH line. They 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 new probes use a large-surface area reference junction of porous PTFE that greatly improves performance in all applications.
