概要

Campbell Scientific’s CS525 pH probe provides reliable, accurate pH measurements that are fully temperature compensated. This probe makes general pH measurements in aqueous or semi-solid solutions, and can be submersed or inserted into tanks, pipelines, and open channels.

利点と特徴

Compatible with the CWS900-series interfaces, allowing it to be used in a wireless sensor network
Electronics are safely embedded in a durable resin body
Elimination of the glass-bulb makes the probe more durable and safer to use
Fully temperature-compensated
Innovative ISFET pH-sensing element used as measurement electrode
Designed and manufactured under stringent quality control conditions in an ISO 9001 environment, ensuring good measurements
Each sensor individually tested
Compatible with all contemporary data loggers (including the CR200X series)

詳細

The CS525 uses SENTRON’s high-tech, Ion Sensitive Field Effect Transistor (ISFET) semi-conductor as its pH-sensitive element, and includes a silver/silver chloride-potassium chloride reference system. The ISFET technology is the most powerful pH monitoring technology available today. This technology considerably reduces the number of acidic or alkaline errors in extreme pH conditions. It allows the CS525 to monitor pH in liquids containing high solids, aggressive chemicals, or biological materials that would clog or contaminate the junction of the traditional glass-bulb pH probes.

The CS525’s rugged design makes it suitable for just about any liquid pH-monitoring application, from laboratory to harsh field applications. The probe’s electronics are safely embedded in a durable PEEK body. Elimination of the glass-bulb removes the possibility of broken glass, making the CS525 more durable and safer to use.

Note: The CS525-L ISFET pH Sensor is highly susceptible to ground looping and galvanic conditions. The best isolation technique to overcome these issues is to use a CWS900-series Wireless Sensor Interface. In many cases, the CS525 can also be isolated by NOT grounding the data logger to an earth ground. Please discuss your application with Campbell Scientific before purchasing the sensor.
