S201CIT pH Sensor, 12mm, Refill, 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

LabSen 803 Glass Combination pH/Temp. Electrode for Purified Water & Low Ion-Concentration Solutions by Apera

Backed by proprietary Swiss sensor technology and materials, the LabSen® 803 3-in-1 pH/Temp. Electrode/Probe is designed for purified water such as drinking water, RO water, distilled water, deionized water, and other low ion-concentration solutions.

Moveable Sleeve Junction - The LabSen 803 pH Electrode/Probe is easy to clean, especially suitable for low ion concentration solutions. The infiltration rate of the electrolyte is determined by the tightness of the sleeve, which can be customized by users to ensure the best performance in every specific sample.

Silver Ion Trap Reference System - The LabSen 803 pH electrode adopts a Silver Ion Trap reference system. On top of the Long-Life reference system, a silver ion trap is added to prevent the junction being blocked by silver sulfide.

Unique Glass Membrane - The LabSen 803 pH Electrode/Probe adopts a Cylindrical glass membrane, which has faster response rate, better repeatability, and built tough - highly resistant to general impact (totally differentiates from the traditional fragile glass bulb membrane).

Patented pH/Temperature combination structure - The temperature element is placed in an independent cavity under the pH glass membrane. With the built-in heat-conducting medium, the temperature sensing speed can be increased by 40%, hence the response time and stability of the pH electrode are greatly improved.

Compatible Apera Instruments' meters: MP511, PH850, PH8500, SX823-B, PH700, PH910, PH950, PH820 and PC820. May NOT work with other brands' meters because the temperature unit might be incompatible.

The electrode is backed up with a 6-month warranty by Apera Instruments.

• Proprietary pH sensor technology and materials from Switzerland
• Unique LabSen cylindrical glass membrane, faster response rate, better repeatability in purified water
• Get stable pH measurements in purified water or low ion-concentration solutions in 30 seconds on average. Say goodbye to annoying fluctuations
• Patented pH/Temperature combination structure, increasing the temperature response time by 40% compared to a conventional isolated built-in thermistor
• Silver Ion Trap Reference System - on top of the Long-Life reference system, a silver ion trap is added to prevent the junction being blocked by silver sulfide
