AI3106 LabSen 551 PVC-body Spear pH Electrode by Apera

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 551 PVC-body pH Electrode is designed for direct soil testing and soil slurry testing.

LabSen S-type spear glass membrane - low resistance and high firmness, rendering fully stabilized readings in 15 to 30 seconds, and is yet 10 times stronger than traditional glass membranes, highly resistant to general impact, eliminating the chance of accidental breakage when inserting into the soil.

Open&Ceramic double-junction with Polymer electrolyte - ensures full contact with test samples while minimizing junction clogs. No need to refill electrolyte.

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 the reference system and extends the service life of the electrode.

The electrode uses a standard BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera MP500) to enable ATC or manually input temperature to achieve temperature compensation.

WD-17002-04 InnoCal NIST-Traceable Calibration, RTD Meter and Probe System Meter+Probe by Oakton

Regardless of the type of thermometry probe your application requires, InnoCal can ensure the accuracy of your meter, probe, or system!

All measurements reported are traceable to SI units via national standards maintained by NIST and performed in compliance with ANSI Z540, ISO17025 and MIL-STD-45662A. See the sample certificate under the "More Info" section to see how InnoCal's certificates provide more information in a concise manner than the rest of the industry.

InnoCal is accredited to ISO/IEC 17025 by the American Association for Laboratory Accreditation (A2LA) under certificate number 1746.01. This accreditation is your assurance that the calibration is performed in a qualified, controlled laboratory which is technically proficient and committed to quality and customer-focused continuous improvement. Our scope of A2LA accreditation can be found under the "More Info" section.

Calibrations on temperature systems (meter and probe) are performed using direct comparison in high-stability liquid using high-precision and SPRT's and displays. Measurements can be performed at four points between -196 and 1300°C. Points are generally selected at standard ITS-90 points across the range of the probe but customer-specified points can be accommodated. Calibrating the probe and meter together produces the highest accuracies.

• NIST-traceable calibration allows you to confirm that the specific asset you purchase does in fact meet the manufacturer's published specification EPA, USDA, ISO and GLP/GMPs standards require regular NIST-Traceable calibration of all test equipment being used in critical applications
• Receive your product calibrated and ready to use rather than sending it to a third-party or internal calibration lab and incurring additional delays
• Calibration service for a RTD meter and probe system

AI3107 LabSen 371 PVC-body Flat pH Electrode by Apera

Built with proprietary sensor technology and premium materials, Apera LabSen 371 POM-body pH Electrode is designed for flat surface pH measurement such as skin, paper, textiles, etc.

Special Flat Glass Membrane - LabSen 371 pH electrode adopts a flat glass membrane with PTFE ring junction, making reliable surface pH test easier than ever.

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 system and extends the service life of the electrode.

The electrode uses a standard BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is 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.

• Proprietary pH sensor technology and premium materials from Switzerland
• Special LabSen flat glass membrane, suitable for flat surface pH measurement such as skin, textiles, paper, etc.
• Long-Life Reference System, improving the stability of reference electrode and prolong the service life of the electrode
• Anti-clogging PTFE ring junction
• No more air bubbles inside the glass membrane thanks to the Swiss blue gel electrolyte.
