0560 9221 922 Dual Type K Thermometer by Testo

The differential thermometer records temperature values from 2 connected thermocouple probes and displays them simultaneously. The reading from an additional temperature probe can also be wirelessly displayed in the testo 922 measuring instrument; i.e. measurement data is transmitted by radio. Differential temperature can be called up immediately. Current measurement data such as max/min data can be printed on the Testo fast printer on site. It is possible to print measurement data once a minute, for example, on the printer if cyclical printing is in operation.

• 2 channel measuring instrument with optional radio probe
• Displays differential temperature
• Cyclical printing of readings, e.g. once a minute
• Continuous display of max/min values
• Hold button to freeze reading
• TopSafe, indestructible case, protects from dirt and impact (option)
• Display light
• On site printout on Testo fast printer

Vividia Waterproof USB Flexible Inspection Camera Borescope Endoscope Microscope with Manual Focus by Oasis Scientific

By connecting the USB Flexible Inspection Camera Borescope Endoscope Microscope to your PC via USB interface, it allows you to perform detailed visual inspection in hard-to-reach places. This inspection camera is powered by a USB connection to your PC, so no batteries are required. The 56cm (1.8ft) flexible cable can be bent into many shapes to fit into unreachable areas. With 0.3M pixels CMOS sensor, 1-50x adjustable magnification, manual focus plus fine auto focus, and four built-in LEDs for illumination, this camera allows you to capture snapshots or videos with rich color throughout a large dynamic range. It is easy to take snapshot by hardware or software control, and the images can be saved, compared and printed. The software which comes with the camera has measurement function for length, arc, and angle. Waterproof camera withstands wet environments. The small 13mm camera head is perfect for up-close visual inspections in small spaces. It is ideal for use in automotive maintenance, electrical repair, plumbing applications, HVAC/R and the visual inspection of otherwise inaccessible areas.

WD-27504-30 Cole-Parmer® Combination Ion-Selective Electrode (ISE), Sodium (Na+) 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 epoxy body
