S655CD pH Sensor, Flat, CPVC, for Insertion by Sensorex

Without the need for system shutdown for electrode maintenance, the insertion assembly allows pH measurements to be made in pressurized tanks and main lines. The assembly's adjustable insertion depth allows it to be placed in a turbulent flow region, enabling it to operate in the selfcleaning mode.

In abrasive applications, the electrode is best positioned flush with the pipe wall or tank wall. High suspended solids and viscous liquid pH measurements are simple with the insertion assembly and electrode pair. The specially designed internal makes the electrode mountable in virtually any direction, including inverted. A 1" full-port ball-valve (Sensorex BV-1) is recommended for installation.

New part number S656CD has four protective pads to reduce pH glass breakage. The S656CD replaces the 970283 which is now obsolete. In addition to the protective pad feature, the S656CD also includes our high performance acrylamide gel that provides longer life in many applications.

• Quick disconnect design saves time and money
• Installs in seconds, no tools necessary
• Flat-surface design resists coating
• CPVC or PVDF construction
• Available with or without ATC elements
• Protective tip reduces pH glass breakage (S656CD)

S200CIT pH Sensor, 12mm, Polymer, Calomel Free by Sensorex

Calomel Free pH electrodes!

The performance of a Calomel electrode is now available without the hazardous Mercury associated with the design. The "Calomel Free" design features an Ag/AgCl based double junction reference with a unique silver ion trap acting as a third junction to impede any silver ion contact with the sample. Reference output is adjusted to deliver the same output as a Calomel electrode using a silver chloride reference.

Glass or Plastic Body Electrodes!

Traditionally, pH electrodes have been made of all glass construction. However, today's thermoplastics are able to construct pH electrodes with durable and chemically resistant bodies to reduce any breakage. The protected design of the plastic body electrode extends over the measuring surface, making the pH glass bulb virtually unbreakable.

Sealed vs. Refillable Reference!

Both sealed and refillable styles are available. Sealed references are gel-filled and maintenance free while refillable designs extend electrode life by having a refillable reference electrolyte.

Features:

• Fast Response...No Silver Ion Contamination
• Use in Place of Calomel pH and Reference Electrodes
• Combination Triple Junction Design
• Uses No Hazardous Calomel Based Material (MERCURYFREE!)/RoHS compliant
• Sealed and Refillable Models
• Glass and Epoxy Body Models

DO7400TC/T DO Sensor, PTFE Membrane, (low range) supplied with customer specified temperature element by Sensorex

Your Dissolved Oxygen (DO) sensor is a galvanic electrochemical device; i.e. it does not require power from your meter or controller to generate its signal. The DO sensor will provide a millivolt signal proportional to the concentration of oxygen in the water (model DO7400, DO7400TC) or 4-20mA current output (models DO7441 and DO7442). The signal output is proportional to ppm of oxygen for probes with millivolt signal output or changes linearly with ppm of oxygen sensors with 4-20mA output. The partial pressure of oxygen, which is directly proportional to the percent saturation of oxygen in a specified sample, can be calculated based upon the oxygen solubility which is a function of temperature, salinity, total atmospheric pressure, etc.

Your Dissolved Oxygen sensor consists of an cathode, anode and an electrolyte separated from your process fluid by an oxygen permeable membrane. The oxygen passing through the membrane reacts at the cathode, giving up electrons, which produces an electrical current.
