6813080 Sensor, CatEx 125 PR Gas by Draeger

The Draeger Sensor Catalytic Ex-Sensors measure multiple gases at the same time--combustible gases and vapors in the air.

Resistance to poisoning

DraegerSensors are robust and easy to handle, and with the DraegerSensor CatEx PR Technology, we have succeeded in developing particularly long-term stable catalytic Ex sensors. Hydrogen sulfide and silicones are known catalytic poisons which may be present themselves in the environment where explosive gases exist. Thanks to a new pellistor composition, the sensors are highly resistant to 'poisoning' from these substances.

Sensitivity to vapors

Unknown gas hazards and higher hydrocarbons pose a particular challenge to the display sensitivity of catalytic sensors. The new CatEx 125 PR and Smart CatEx (PR) sensors have such a sensitivity. The detection of all hydrocarbons (from methane to nonane) has been confirmed with a measurement certificate for the device series Draeger X-am® 1/2/5000 and Draeger X-am® 7000.

Optimised for extreme conditions

The design of the new sensor CatEx 125 Mining PR makes it particularly impact-resistant and thus optimised for the harsh conditions in the mining industry.

From LEL to 100 % by vol.

Our catalytic sensors are suitable for measurements from the lower explosion limit (LEL) to 100 % by vol.

WD-27502-43 Cole-Parmer® Ion-Selective Electrode (ISE), Sodium, Double-Junction, BNC by Oakton

Whether your application involves end point determinations in potentiometric titrations or continuous monitoring of specific ions, we can help you find the right electrode for the job. These fast and accurate electrodes do not require an external reference - they're easier to use than separate sensing and reference half-cell electrodes. All Cole-Parmer electrodes are double-junction combination ion-selective electrodes and are convenient to use in places where two electrodes won't fit. All electrodes include a 30-mL bottle of reference solution, a reference filling pipette, 1-m cable, BNC connector, and an instruction manual. Solid-state electrodes also have twelve polishing strips.

Economy Epoxy Electrodes have a durable epoxy body and are well-suited for portable field applications. Outer reference chamber is silver-free and resists contamination. These electrodes are refillable.

Laboratory Glass Electrodes are double-junction in design, with a glass body that provides high-quality measurements for your laboratory applications. Improved glass seal enhances performance and reliability. Sealed inner junctions and refillable outer junctions accommodate special reference fill solutions - ideal for low-concentration measurements. Use electrodes with a meter that has a resolution of 0.1 mV for the most accurate results. Many meters in our "pH/Ion Meters" section have 0.1 mV resolution; several also give direct readings in ppm. For monitoring ions not listed below, call our Application Specialists for more electrode application information.

• Cost-effective choices that are easy to use
• Easily fit into small spaces - no additional reference electrode is needed
• Sodium (Na⁺) ISE with glass body
