FC51K 200uL Low Volume PVDF Flow Cell includes 2 each 1/16" Tube Fittings by Sensorex

Sensorex manufactures fast response 50 and 200 microliter internal volume flow cells for pH measurement. All cells are made of clear Acrylic or Kynar (PVDF). Designs include 1/16" inlet and outlet fittings. All cells use the standard, economical Sensorex 450CD Flat Surface Combination pH/Reference Electrode or a special version of 450CD with 100psig pressure tolerance (model 970277).

The pH Detectors are designed for use with a variety of instrumental techniques such as FIA, HPLC and IEF and are also used to continuously monitor the pH of low volume flows in bench scale chemical systems.

Both the 50 and 200 microliter internal volume flow cells areavailable in acrylic or PVDF and are supplied with inlet and outlet fittings sized for standard 1/16" OD tubing. The cells' ports have 1/4-28 threads which accept a variety of other tube fittings.

Very low internal volumes are achieved by using a flat surface pH electrode located at the top of the flow cavity. The resulting rectangular cross-section flow path has no protruding parts which could interfere with a clean sweeping flow. The result of this design is the fast system response shown on the performance curves on page 2.

The Flat Surface Electrode, Sensorex Model 450CD, is a combination pH/Reference electrode with double reference junction design. It includes both a pH and reference half cell. The reference electrode is a sealed, gel-filled design and includes a peripheral, semi-porous polyethylene junction.

WD-27502-19 Cole-Parmer® Ion-Selective Electrode (ISE), Fluoride, 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
• Fluoride (F^-2) ISE with glass body

0635 9431 Vane Probe (Ø 100 mm) with Bluetooth, includes Temperature Sensor by Testo

Use the fixed cable on the handle to connect the vane probe to the measuring instrument (please order separately).

The clearly structured measurement menu for volume flow enables the measuring instrument to be operated intuitively. The volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed in the measuring instrument.

Particularly useful: press the button on the vane probe to operate the measuring instrument. For example, to store individual readings for multi-point mean calculation or to start and stop measurement series for mean calculation over time.

Space-saving: more applications, less equipment

Endlessly versatile: a universal handle can be connected to all probe heads - so you can master more applications using less equipment and save space.

Order the Bluetooth® handle to make it more convenient to carry out your measurement and guarantee less cable clutter in the case. This transmits the readings to the measuring instrument from a distance of up to 20 metres. If the vane needs to be replaced in the distant future, you can change the probe head.

If required, you can also fit the vane probe with the extendable telescope with 90° angle and, if necessary, the telescope extension (both can be ordered separately; in combination 2 m long). This makes it easy to measure at ceiling outlets.

Intelligent calibration concept

You will get exceptionally accurate measurement results with the digital vane probe, because the measuring instrument makes measurement uncertainty a thing of the past. You only need to send the probe head in for calibration so the measuring instrument remains in continuous use.

Areas of application for the vane probe

Air/ceiling outlets: Use the vane probe to determine air velocity and volume flow at air outlets. During loop-pattern scanning of the grille's cross section, the air velocity values are integrated and averaged across a large area of 100 mm. As a result, precise measurement results are achieved with the loop measurement.

For measurements at ceiling outlets: the extendable telescope (1.0 m long) with easy-to-read scaling and 90° angle is easy to attach to the vane probe. The 90° angle ensures that the probe is positioned correctly under the ceiling. For high ceilings, you can also use the telescope extension, attaining a total length of 2 metres (please order the extendable telescope and telescope extension separately).

Plate outlets, ventilation grilles and swirl outlets: For convenient, accurate measurements at plate outlets and ventilation grilles, we recommend using the vane probe with the testovent 417 funnel set (please order separately). This guarantees simple testing of incoming/outgoing air - such as in the controlled ventilation of living spaces.

If you add in the volume flow straightener (please order separately), an impressively high level of precision can be achieved when carrying out measurements at swirl outlets.

• Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature
• Precise: get the right results in next to no time, even in turbulent air flow - using the optionally available funnel set and volume flow straightener
• Convenient: probe with a practical button on the handle for storing individual readings, convenient measurement at ceiling outlets with optional telescope (up to 1 m)
• Intelligent calibration concept

Includes:

Vane probe (Ø 100 mm) including temperature sensor (consisting of 100 mm vane probe head, handle adapter and cable handle (cable length 1.4 m)), bracket for testovent measurement funnel, 4 x AA batteries and calibration protocol.
