LabSen 823 Glass Combination pH/Temp. Electrode for Dairy Products and Liquid Food by Apera

Backed by proprietary Swiss sensor technologies and materials, the LabSen® 823 Glass Combination pH/Temperature Electrode/Probe is designed for testing pH for dairy products such as milk, cream, yogurt, and other liquid food such as mayonnaise, jam, BBQ sauce, syrup, etc.

Silver Ion Trap Reference System+Protelyte Electrolyte - The LabSen 823 pH/Temperature Electrode/Probe adopts a Silver Ion Trap reference system and Protelyte reference solution. On top of the Long-Life reference system, a silver ion trap is added to prevent the junction from being blocked or contaminated by proteins.

LabSen unique blue hemispherical glass membrane - faster response time, better repeatability, and built tough, highly resistant to general impact (totally differentiates from the traditional fragile glass bulb membrane); and can be tested in high-temperature samples (up to 225°F).

Patented pH/Temperature combination structure - The temperature element is placed in an independent cavity under the pH glass membrane. With the built-in heat conducting medium, the temperature sensing speed can be increased by 40%, hence the response time and stability of the pH electrode are greatly improved.

Compatible with Apera Instruments' meters such as PH700, SX823-B, MP511, PH800, and PC800. May NOT work with other brands' meters because the temperature unit might be incompatible.

The electrode is backed up with a 6-month warranty by Apera Instruments.

874337 Chemcassette Tape, Mineral Acids by Honeywell Analytics

Chemcassette® is the unique trademarked name for a calibration free toxic gas detection method that uses an optical scanning system to detect the presence of gas by a colour change on the specially chemically impregnated paper tape. Chemcassette® technology is highly specific and reacts extremely fast to the presence of parts per billion (ppb) levels of many hazardous gases. Over 200,000 points of gas detection are currently maintained by the Chemcassette® sensing technology at any given time around the World in some of the most critical safety applications possible.

Each Chemcassette® is manufactured to traceable ISO 9000 manufacturing standards by a world class team of highly trained chemists and each batch is calibrated with ultra pure gas that is traceable to nationally accepted standards. This means that the end user does not have to provide calibration facilities themselves thereby saving cost and reducing risks to their own staff.

Efficient high volume manufacturing techniques means that there is always available Chemcassette® in stock that can be shipped anywhere in the World so that our customers are never left without adequate safety cover. Application support with expert gas detection chemists is available by phone and e-mail and is supported with many years of technical application notes and help to diagnose common support issues.

Should there be any concern regarding the performance of an individual Chemcassette®, a free of charge evaluation will be performed to trouble shoot the observed scenario using the award winning quality management system "Customer Discrepancy Report" CDR. Every CDR completed by a customer is guaranteed a full response and the outcome is reported directly back to the end user to ensure a complete resolution process.

Each Chemcassette® is backed with a full warranty and we have over 20 years of experience regarding the quality control of our proven sensing technology.

Additional Features and Benefits:

• Visible proof of a gas release event
• Greater sensitivity (detection down to parts per billion levels)
• Superior selectivity (less cross-interference with other gases)
• Fast response time
• Low false alarm occurrence
• Stability (consistent, repeatable operation)
• No calibration required
• Easy to use
• Available in fixed and portable instrumentation

94175 Reducer/Corrector f/6.3 by Celestron

This combination focal reducer and field corrector lens accessory works with all Celestron 5", 6", 8", 9 1/4", 11" and 14" Schmidt-Cassegrain telescopes. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality. The Reducer/Corrector is f/6.3 for C5, C6, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope.

If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, it reduces exposure time by a factor of 3.

Celestron doesn't offer a f/6.3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6.3 Reducer/Corrector. Results are amazing both visually and photographically.

94460-98 Traceable® High-Accuracy Fridge/Freezer Thermometer with Calibration; 1 SS Probe by Digi-Sense

Easily and accurately monitor temperature in most scientific, industrial, or general-purpose applications. Built-in alarms alert continuously until reset. Unit displays the exact time and date when thermometer alarms are triggered. Program the alarm in 0.1° increments. Thermometers have one-button field calibration and date/time stamp. Meters that accept two probes are ideal for monitoring two unique areas that are near each other. Probe comes with a microcable that permits a door to close on it.

Traceable® products are calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately.

NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.

Stainless steel probe is ideal for measuring temperatures of air, liquids, and semisolids; sensor stem measures 6.25"L x 1/8" dia (15.9 x 0.3 cm).

• Get accurate, reliable measurements with included NIST-traceable calibration
• Resolution of 0.01° and accuracy of ±0.6°F (±0.3°C)
• Visual and audible alarms signal continuously until reset
• Durable stainless steel probe withstand both low and high temperatures
