• Allows monitoring in variable chemical environments: Double junction reference protection prevents reference cell contamination
• Accurate measurements across full pH scale (0-14)
• Instantly ready for use: Shipped in storage bottle for long shelf life – guaranteed for one year
• Compatible with any meter accepting a BNC connector
• One year limited warranty: We stand behind all our products with the Sensorex Guarantee

S550C-ORP/BNC ORP Electrode, single-junction, epoxy body, Pt pinsensor by Sensorex

Some of our laboratory ORP electrodes, including the S550C-ORP/BNC, have gotten an update! Looking for a polymer body, double junction ORP electrode for lab use? Check out the ORP2000, which replaces the S550C-ORP in our new laboratory ORP electrode line.

S550CD-ORP/BNC ORP Electrode, double-junction, epoxy body, Pt pin sensor by Sensorex

When measuring samples such as wastewaster that may contain proteins, heavy metals, or other contaminants, it is important to use an ORP sensor (REDOX sensor) designed to withstand unpredictable chemical environments. The S550CD-ORP/BNC features double junction reference protection, which prevents contamination by sample components that interact with silver (Ag). The durable Ultem® body ensures extensive chemical compatibility, making the S550CD-ORP/BNC a highly versatile analytical tool.

• Virtually unbreakable with durable Ultem® body construction and recessed protected glass
• Reliable and accurate ORP / REDOX measurements
• No refilling or maintenance required with sealed gel-filled design
• Instantly ready for use and shipped in storage bottle for long shelf life – guaranteed for one year
• One year limited warranty

SG1041CD/BNC pHase Renew, pH electrode, BNC, Double junction by Sensorex

In laboratory environments such as medical, biological, and materials science research groups, samples and test conditions are constantly changing, but accuracy is always critical. The SG1041CD/BNC is a highly versatile glass combination pH electrode, specially designed to respond quickly and accurately to rapid temperature changes. The high sensitivity internals allow testing of low ionic samples. Safely measure samples containing heavy metals, TRIS buffer, or proteins thanks to the double junction reference design, which prevents fouling. Even test highly reactive chemicals: with a glass body, the SG1041CD/BNC is inert to a wide range of chemical reactions. Sensorex RapidRenew reference design flushes away contaminants that might build up and slow response.

• Our most sensitive laboratory electrode: accurate to 0.04 pH in tests across full recommended temperature range
• Easily maximize measurement repeatability: Rapid renew reference system for quick refilling
• Safe for use with reactive chemicals: Glass bodies are inert to many chemical reactions
• Ideal for difficult sample types: Double junction reference protection for testing samples containing heavy metals, TRIS buffer, and other contaminants
• Ready for wet or corrosive environments: BNC protects meter connection

SG200C/BNC pH Electrode, sealed single-junction, glass body by Sensorex

Environmental, wastewater, and other sampling applications may expose electrodes to unknown contaminants. Over time, exposure to contaminants such as heavy metals and reactive chemicals, will take a toll on a sensor's functional components. The best sensors for these types of applications are built to safely handle contaminants to maximize working lifetime. Our SG200C/BNC is a glass electrode with double junction reference design to prevent fouling by sample contaminants that interact with Silver (Ag). The refillable reference junction allows users to replace the liquid fill solution as it becomes depleted or contaminated, instead of replacing the whole sensor.

• Accurate measurements across full pH scale (0-14)
• Maximum chemical compatibility: glass electrode bodies are inert to most reactions
• Extended lifetime: Refillable reference junction allows sensor maintenance, saving replacement costs
• Great for wet or corrosive environments: BNC protects meter connection
• Compatible with any meter accepting BNC
• Instantly ready for use: Shipped in storage bottle for long shelf life – guaranteed for one year
• One year limited warranty: We stand behind all our products with the Sensorex Guarantee

SG350CD/BNC pH Electrode, sealed double-junction, glass body, 9.5 mm dia, 300 mm L by Sensorex

Surfaces like paper, leather, electrophoresis gels and agar plates may be difficult to measure with traditional pH glass bulbs due to concerns about breakage. A flat electrode like our SG350CD/BNC, is ideally suited for these types of pH measurements as well as measurements of suspended sludges and slurries. In addition to its specially designed measurement surface, the SG350CD/BNC features double junction construction, which prevents contamination and allows testing of samples containing heavy metals or proteins.

• Perfect for gels and slurries: Flat electrode measurement surface designed for testing special sample types
• Accurate measurements across full pH scale (0-14)
• Highly adaptable: Compatible with any pH meter accepting BNC
• Low maintenance: Gel-filled electrode reference design with double junction to prevent contamination
• Instantly ready for use: Shipped in storage bottle for long shelf life – guaranteed for one year
• One year limited warranty: We stand behind all our products with the Sensorex Guarantee
