WD-27502-31 Cole-Parmer® Ion-Selective Electrode (ISE), Nitrate, 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

61-1001-05SS Hydrogen specific LEL sensor with XP stainless steel j-box, CSA type by RKI Instruments

When working on potentially hazardous jobsites, safety managers should look for workplace safety solutions that are dependable and steadfast. When lives are on the line, a workplace cannot afford subpar safety products. That is why, at RKI Instruments, workplace safety is a top priority. Their Research and Development team work daily to integrate the latest technology with the best industry practices. With a reputation for excellent products, RKI Instruments introduces the latest in direct connect sensor technology. Designed for use in Class 1, Division 2 hazardous environments, the Direct Connect Sensors are designed specifically for RKI Beacon 110, 200, and 410 controllers.

Direct Connect Sensors

The RKI Direct Connect Sensors series gas sensors are state of the art gas detection sensors available for LEL, H2 Specific LEL, LEL IR, Oxygen, H2S, CO, CO2, and a variety of toxic gases. To use the Direct Connect Sensors, they can be used for remote detection by mounting them onto explosion proof junction boxes, or they can mount directly onto controllers and be used as a completely standalone system. Their unique plugin design allows for a quick and easy tool free installation on jobsites.

Detection solutions for a variety of hazardous environments

The Direct Connect Sensors are designed to be use in both indoor and outdoor settings. Additionally, some of the sensors are available in explosion proof models. The explosion proof models utilize a patented coating which serves double duty as also being water repellant. Users can also purchase splash guards to protect the sensors from very wet conditions.

Sensor Technology

Each sensor is crafted with stainless steel and housed in cast aluminum (stainless steel housing is available for some sensors). The Direct Connect Sensors are available in 2 forms: explosion proof and non-explosion proof. The explosion proof sensors are available as catalytic sensors for LEL, and LEL H2 specific. For hydrogen sulfide and carbon monoxide, the sensors utilize electrochemical technology which provides incredibly specific accuracy and quick response. Oxygen sensors work with galvanic technology, and infrared sensors for methane, hydrocarbons, and carbon dioxide. Non-explosion proof uses a galvanic sensor for oxygen; electrochemical sensors for hydrogen sulfide, carbon monoxide and other toxic gases; and infrared for carbon dioxide. Both explosion proof and non-explosion proof have 1 year warranties for materials and craftsmanship.

Specifications

The response times are under 30 seconds for all gases except hydrogen sulfide and carbon monoxide in the non-explosion versions (with a response time of 35 seconds) and non-explosion proof model sensor for toxic gases which has a 60 second response time. The life expectancy of all sensors are between 2 and 5 years.

The Direct Connect Sensors are compatible with several RKI Industries' accessories including calibration adaptors, flow through adaptors, remote horns and lights, calibration kits, battery backups, splash guards, air aspirator adaptors, and dataloggers.

72-PQX-E GX-3R Pro 1 Gas Personal Monitor - H2S - No Additional Toxic Sensor - Li-Ion Battery Pack Only (No Charger) by RKI Instruments

The GX-3R Pro is the world's smallest 5-gas monitor weighing only 4.58 ounces and fits in the palm of your hand (2.9" W x 2.6" H x 1.06" D). It simultaneously monitors and displays 5 different gases. In addition to monitoring standard confined space gases, LEL, O₂, CO, & H₂S, the GX-3R Pro has a 5th channel where you can add infrared or toxic sensors. Two of the four sensor slots have interchangeable sensors providing flexible configurations, which can easily be changed in the field.

72-RH-F GX-3R 2-Gas Confined Space Monitor, LEL / H2S with Li-Ion Battery Pack with 100-240 VAC and 12 VDC Chargers by RKI Instruments

OSHA defines the breathing zone as a ten inch radius around the worker's nose and mouth, and requires that worker exposure monitoring air samples be collected in the breathing zone. Air sampling filters may be attached to the collar or lapel. Traditionally this means only a single gas monitor would be small enough for a worker to practically wear a gas monitor 'In the breathing zone'. Now there is a 4 gas monitor smaller than many single gas monitors.

The GX-3R is the worlds smallest 4 gas monitor weighing only 3.52 ounces and can comfortably be clipped within a worker's breathing zone (2.2" W x 2.55" H x 1.02" D). It simultaneously monitors and displays LEL combustibles, O₂, CO (Hydrogen compensated CO also available), and H₂S.

The GX-3R represents the latest evolution of gas detection technology utilizing a new generation of micro sensors. The LEL sensor has a unique design with two active filaments in one sensor to increase it's resistance to silicone poisoning. If one filament gets poisoned the second filament takes over. The new O₂ sensor is electrochemical with a 3 to 5 year life span. H₂S and CO are now available in a combo micro sensor.

Safety supervisors will appreciate the non-compliance indicator. The instrument flashes it's 3 LED lights every 30 seconds in the following conditions; if the instrument has not been bump tested, or if calibration is due, or if there was a gas alarm event. The 3 LED lights will continue to flash once every 30 seconds until the non-compliance condition has been resolved. The 30 second interval is adjustable.

Features

• Smallest & lightest 4 gas monitor: 2.2" W x 2.55" H x 1.02" D, 3.52 ounces
