AI3101 LabSen 211 Glass-body pH Electrode for General Water Solutions (TRIS compatible) by Apera

Built with proprietary sensor technology and materials from Switzerland, Apera LabSen 211 pH Electrode is ideal for professional lab and field pH measurement of general water solutions.

LabSen S-type hemispherical 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.

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.

• Proprietary sensor technology and premium materials from Switzerland
• Built with LabSen S-type hemispherical glass membrane, featuring low resistance (fast response) and high firmness
• No more air bubbles inside the glass membrane thanks to the Swiss blue gel electrolyte.
• Long-Life Reference System improves the stability of reference electrode and extends the service life of the electrode
• Compatible with TRIS buffers

LabSen 213 Glass Combination pH/Temp. Electrode for General Water Solutions (TRIS compatible) by Apera

Backed by proprietary Swiss sensor technology and materials, the Apera Instruments LabSen® 213 Glass 3-in-1 pH/Temp. Electrode is designed for general water solutions in scientific research and quality control. This electrode is compatible with TRIS buffer solutions.

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).

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 electrode and extends the service life of the electrode.

The 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 Apera Instruments' meters: PH700, SX823-B, MP511, PH910, PH950, PH850, PH8500, PH820. May NOT work with other brands' meters because the temperature unit might be incompatible.

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

• Proprietary pH sensor technology and materials from Switzerland
• Unique LabSen® blue hemispherical glass membrane - fast response rate and impact-resistant
• Patented pH/Temperature combination structure, increasing the temperature response time by 40% compared to a conventional isolated built-in thermistor
• Say goodbye to air bubbles inside the bulb thanks to the Swiss blue inner gel solution.
• Long-Life Reference System, improving the stability of the reference electrode and prolong the service life of the electrode
