S350CDHF pH Sensor, Flat, Polymer, 12mm, HF by Sensorex

The specification sheet serves as an addendum to the pH LabSpecs sheet and covers all lab pH electrodes suitable for use in hydrofluoric acid.

Specifications differences for use in hydrofluoric acid (HF) are shown in SPECIFICATIONS section below. Please note 2 major differences as compared to standard electrodes. First, pH range is 0-12 not 0-14. Second, the temperature range is 0-50 deg C.

This series of electrodes are compatible with any lab or portable pH meter. Calibration of these electrodes is as normal with any standard pH electrode using standard pH buffer solutions.

• Resist attack and etching from HF (up to 2% v/v)
• Resist coating and fouling
• Compatible with any pH meter

Measuring Range: -50 to +250 °C

Part Number: M197150VN

3177 Benchtop, Conductivity/Temperature/TDS Meter by Jenco

The Basis Series Conductivity/TDS/Salinity benchtop is the latest entry-level meter from a line that is renowned for its reading quality, now with a refined user experience and improved usability.

• Renowned accuracy and repeatability
• Upgraded user experience and usability
• Low cost of ownership

Well-designed, Inside and Out

The Basis Series Conductivity/TDS/Salinity meter, along with the pH/mV model, forms the foundation of Jenco's benchtop meter offerings and comes from a long line of distinguished benchtop meters, where low cost of ownership, reading quality and build quality take precedent.

Benchtop Conductivity/TDS/Salinity Meter Renowned for Accuracy and Repeatability

The reason Jenco is consistently contracted to build products for well-respected brands and the reason we can consistently win the trust of end-users is due to our reputation for being focused on reading quality. Do the right things in the right way, no cutting corners.

• Repeatable readings with ±0.5% full scale accurate across entire measurement range
• Uses 2-wire conductivity cells with adjustable k=0.01, k=0.1, k=1 and k=10 cell constants for improved flexibility and accuracy
• Each and every unit is hand calibrated and QC'ed by at least 2 teams
• Simple one point calibration

Upgraded User Experience and Usability

While the Basis Series provides the quality readings you expect, it does so in a design that optimizes its user-friendliness and minimizes its footprint on your workstation.

• Streamlined, modern and smaller design creates clutter-free workspace
• Large, high contrast LCD
• Convenient one point calibration
• Automatically determines the best conductivity ranges to display readings

• Splash-resistant case made with durable, reinforced plastic for added protection
• AC adaptor or battery powered

Improved Electrode Serviceability and Low Cost of Ownership

The Basis Series Conductivity/TDS/Salinity meter uses a common Jenco 8-pin DIN connector so it works with our other conductivity electrodes. The decision to make the electrode arm a detached, optional accessory further allows the Basis Series to be setup in the way that works best for you.

• Splash-resistant case is made with durable, reinforced plastic for added protection
• 8-pin DIN connector for conductivity cell & 10k thermistor
• Optional, detached electrode arm

LabSen 223 Glass Combination pH/Temp. Electrode for Viscous and Low Ion Concentration Samples by Apera

Backed by proprietary Swiss sensor technology and materials, LabSen® 223 Glass Combination pH/Temp. Electrode is designed for viscous and low ion concentration samples' pH testing and ideal for titration. The electrode is compatible with TRIS buffer solutions.

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

• Moveable Sleeve Junction - easy to clean, especially suitable for low ion concentration solution and non-aqueous solution. The infiltration rate of the electrolyte is determined by the tightness of the sleeve during installation.
• Long-Life Reference System - composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of reference electrode and extends the service life of the electrode.
• Special Glass Membrane - The Cylindrical glass membrane is highly resistant to general impact (the traditional glass bulb membrane is a lot more fragile), and can be tested in high-temperature samples (up to 176°F).
• Built-in temperature sensor for Automatic Temperature Compensation

18004-16 Traceable ONE Single-Use USB Temperature Data Logger, 10 Day, 1 Minute Interval, -20 to -15°C; 10/pk by Digi-Sense

These data loggers can be used for monitoring and recording temperatures during shipments, storage, or experiments. They are ideal for food, pharmaceutical, or laboratory use any application where a small accurate datalogger is required.

The data logger features a time delay of 30 minutes so the logger will not alert when the temperature is within the alarm zone, until the delay time elapses. Protective plastic pouch keeps logger dry, eliminating concerns when shipping materials with cold packs, ice, or in damp environments. To maintain IP67 waterproof rating, do not tear open pouch before data download.

Products have an individually-numbered Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• LED alarm indicator for visual status indication
• Time delay of 30 minutes before logging begins for enhanced logging accuracy
• Protective plastic pouch maintains waterproof IP67 rating
• Bar code for in-house scanning
• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Compact, single-use datalogger with 10 day logging duration in 1 minute intervals
• Low to High alarm parameter range of -20 to -15°C

Includes

Battery (3.0 V CR2450 lithium) and NIST-Traceable calibration certificate with data.
