LabSen 851-3 Glass-body pH Electrode for Highly Viscous Solutions by Apera

Backed by proprietary Swiss sensor technology and materials, the LabSen 851-3 Glass Pre-Pressurized Combination pH Electrode is designed for pH measurement for highly viscous solutions such as cosmetics, paint, resin, glue, and etc.

Pre-pressurized reference system - a pressure is pre-filled inside the LabSen 851-3 electrode so that the electrolyte can continue to flow through the junction. Even if a high viscous solution is tested, the blockage of the junction can also be avoided

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors, such as Apera Instruments MP511, SX811, PH700, PH800, PC800, PH820 and PC820. The temperature sensor is not built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to realize temperature compensation.

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

• Proprietary pH sensor technology and materials from Switzerland
• Pre-pressurized reference system: pressure is pre-filled inside the electrode so that the electrolyte can continue to flow through the junction. Even if a high viscous solution is tested, the blockage of the junction can also be avoided
• Standard BNC Connector
• 6-Month Warranty fulfilled by Apera Instruments

18004-21 Traceable ONE Single-Use USB Temperature Data Logger, 60 Day, 6 Minute Interval, 2 to 8°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
