S300CIT pH Sensor, Polymer, 9.5mm, 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

S350CDHF pH Sensor, Flat, Polymer, 12mm, HF by Sensorex

The specification sheet serves as an addendum to the pH LabSpecs sheet and covers all lab pH electrodes suitable for use in hydrofluoric acid.

Specifications differences for use in hydrofluoric acid (HF) are shown in SPECIFICATIONS section below. Please note 2 major differences as compared to standard electrodes. First, pH range is 0-12 not 0-14. Second, the temperature range is 0-50 deg C.

This series of electrodes are compatible with any lab or portable pH meter. Calibration of these electrodes is as normal with any standard pH electrode using standard pH buffer solutions.

• Resist attack and etching from HF (up to 2% v/v)
• Resist coating and fouling
• Compatible with any pH meter

S645CD pH Sensor, Flat, CPVC, Side Stream by Sensorex

Side stream mountings are particularly useful in applications involving oily coating or moderately viscous materials. This mounting hardware allows the velocity past the electrode to be controlled in a predictable manner. In the 3/4 inch flow cell, restricted 1/4 inch flow channel, each GPM of flow provides two ft/sec past the flat electrode's sensing surface. Flow rates of three to five GPM provide adequate cleaning velocities. Exact control of flow rates is not required.

In viscous material applications the above flow rates may be difficult to achieve; however, lower rates still provide flow in shear to assure that fresh material is at the measuring surface.

• Quick disconnect design saves time and money
• Installs in seconds, no tools needed
• Flat surface design resists coating
• CPVC and PVDF construction
• Available with or without ATC elements

S650CD pH Sensor, Flat, CPVC, Submersion by Sensorex

The submersion pH and ORP electrodes from Sensorex are designed for measurements in tanks, flumes and sewer lines. Submersion designs are are also well suited for applications with high suspended solids or where flocculation operations require low velocities or in tanks with high agitation.

Where low velocities are present and coating is a problem, the electrode can be mounted at a 45 degree angle facing into the flow so as to obtain increased scrubbing action across the measuring surface.

The cartridge quick disconnect design makes changing electrodes a snap and minimizes down time due to electrode maintenance.

Model S651CD offers pH glass protection feature and the extra performance of acrylamide reference gel.

• Quick Disconnect Design Saves Time and Money
• Installs in Seconds, No Tools Needed
• Flat Surface Design Resists Coating
• CPVC or PVDF Models Available
• Available with or without ATC Elements
