AI3102 LabSen 221 Glass-body pH Electrode for Viscous and Low Ion Concentration Samples by Apera

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 221 Glass-body pH Electrode is designed for titration and low ionic strength solutions as well as general water solutions. The electrode is compatible with TRIS buffer solutions.

LabSen S-type cylindrical 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.

Movable Sleeve Junction - easy to clean, especially suitable for low ionic strength solutions, emulsions, and suspensions. The infiltration rate of the electrolyte can be adjusted by the tightness of the sleeve.

The electrode uses a 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.

• Built with LabSen S-type glass membrane, featuring fast response and high firmness
• Movable Sleeve Junction - easy to clean, adjustable infiltration rate
• Long-Life Reference System, improving the stability of the reference and extends the electrode's service life
• No more air bubbles inside the glass membrane thanks to the Swiss blue gel electrolyte.

08009-22 ASTM Like Liquid-In-Glass Thermometer; 33F / Low Aniline Point, 50mm Immersion, -36.5 to 107.5F, Organic Liquid Fill by Digi-Sense

These thermometers are precision manufactured to conform to ASTM E-1 specifications except for not being mercury filled. Designed for use in quality control laboratories or when mercury filled thermometers can not be used but where ASTM standards are still needed. ASTM established thermometer standards suited for special applications, and assigned an ASTM number according to each specification.

Thermometers feature permanently fused markings, blue spirit liquid, white background glass; are also individually serial numbered.

• Designed for specific ASTM (American Society for Testing and Materials) test methods
• Nonmercury blue spirit liquid

WD-17000-06 InnoCal NIST-Traceable Calibration; Thermistor Meter (Meter) by Oakton

All calibration certificates contain as-found and as-left data, estimated measurement uncertainties (emu's) and test uncertainty ratios (TUR's) at no additional cost!

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

InnoCal's Metrology Laboratory is accredited to ISO/IEC Guide 25 by the American Association for Laboratory Accreditation (A2LA); certificate number 1746.01. This accreditation is your assurance that one of the foremost outside auditing agencies approves of our internal laboratory policies and procedures.

• Provides traceability to NIST
• Lists the environmental conditions present at time of calibration
• Certificate lists actual values, uncertainties, and tolerances
• Regular calibration helps you meet ISO, EPA, GLPs/GMPs and other quality standards
• Not an accredited certificate

AI3105 LabSen 251 Glass-body Spear pH Electrode for Semi-Solid Samples by Apera

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 251 Glass-body pH Electrode is designed for direct pH test of semi-solid samples as well as general water solutions.

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 semi-solid samples.

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 reference electrode 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.

• Spear sensor designed for direct pH test of semi-solid samples
• LabSen S-type glass membrane, featuring fast response and high firmness

LabSen 553 Plastic Combination Spear pH/Temp. Electrode by Apera

Backed by proprietary Swiss sensor technology and materials, the LabSen® 553 3-in-1 pH/Temp. Spear Electrode/Sensor/Tester is designed for testing soil directly (This is a replacement probe for Apera PH850-SL, PH9500-SL).

Long-Life Reference System - The LabSen 553 pH electrode adopts a long-life reference system, which is 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.

Polymer Electrolyte - The solid polymer electrolyte makes the electrode hard to be contaminated and maintenance-free.

Special Glass Membrane - The LabSen 553 pH electrode adopts a spear sensor tip, which is ideal for directly testing semi-solid samples like soil.

Compatible Apera Instruments' meters: PH700, SX823-B, MP511, PH800, 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.

• Proprietary pH sensor technology and materials from Switzerland
• Special LabSen Spear pH sensor tip, ideal for direct soil pH testing. No more slurry making.
• Pom housing, ideal for use in harsh environments
• Polymer electrolyte - not more clogged junction
• Long-life reference system, improving the stability of reference electrode and prolong the service life of the electrode
