LabSen 803 Glass Combination pH/Temp. Electrode for Purified Water & Low Ion-Concentration Solutions by Apera

Backed by proprietary Swiss sensor technology and materials, the LabSen® 803 3-in-1 pH/Temp. Electrode/Probe is designed for purified water such as drinking water, RO water, distilled water, deionized water, and other low ion-concentration solutions.

Moveable Sleeve Junction - The LabSen 803 pH Electrode/Probe is easy to clean, especially suitable for low ion concentration solutions. The infiltration rate of the electrolyte is determined by the tightness of the sleeve, which can be customized by users to ensure the best performance in every specific sample.

Silver Ion Trap Reference System - The LabSen 803 pH electrode adopts a Silver Ion Trap reference system. On top of the Long-Life reference system, a silver ion trap is added to prevent the junction being blocked by silver sulfide.

Unique Glass Membrane - The LabSen 803 pH Electrode/Probe adopts a Cylindrical glass membrane, which has faster response rate, better repeatability, and built tough - highly resistant to general impact (totally differentiates from the traditional fragile glass bulb membrane).

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: MP511, PH850, PH8500, SX823-B, PH700, PH910, PH950, PH820 and PC820. 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
• Unique LabSen cylindrical glass membrane, faster response rate, better repeatability in purified water
• Get stable pH measurements in purified water or low ion-concentration solutions in 30 seconds on average. Say goodbye to annoying fluctuations
• Patented pH/Temperature combination structure, increasing the temperature response time by 40% compared to a conventional isolated built-in thermistor
• Silver Ion Trap Reference System - on top of the Long-Life reference system, a silver ion trap is added to prevent the junction being blocked by silver sulfide

CS200-C-N-AB-2-A-N CS200 Light Duty Online Conductivity Sensor, Platinum, 12mm, K=1.0, 3FT, BNC by Sensorex

The CS200 and CS200TC conductivity probes are a cost effective solution for measuring conductivity in light industrial and laboratory applications.

Models CS200 and CS200TC feature platinized measuring surfaces that provide accurate and repeatable measurements. Rugged epoxy bodies make the sensors virtually unbreakable. These are an excellent choice to use as standard laboratory conductivity electrodes.

By adding a simple mounting gland fitting, customers may use these in process applications. Mount them in-line, in a pipe "T" fitting, or submerse them into a tank.

Features

• Ideal for laboratory and light duty process applicationsAvailable with or without ATC (temperature sensor)
• Easy to submerge in a tank or mount inline in a pipe
• Cell constant choices of 0.1, 1, or 10
• Compatible with most portable and benchtop meters
