WD-35634-55 CTSTestr™ 50P Pin-Style Waterproof Pocket Conductivity/TDS/Salinity Tester, Premium 50 Series by Oakton

New design stands up to the challenges of measuring water quality even stands upright

The Oakton conductivity pocket testers stand up to everyday use, harsh environments, and the test of time. The testers can even stand upright when the cap is used as the stabilizing base. When you choose one of these conductivity testers, you get a pocketful of useful features and benefits.

• Easy-to-replace sensor module lets you use the tester body over and over again
• Intuitive interface has self-diagnostic error messages, and battery-life and stable reading indicators
• Simple operation at your fingertips with MENU button, 1-button calibration, and HOLD button to freeze readings for recording
• Valox® body resists most chemicals and is rugged, dustproof, waterproof, and IP67 rated
• Leakproof cap functions as a sample cup, hydrating cup, and stabilizing base to stand the tester upright
• Uses common AAA batteries

Measuring Range: -100 to +400 °C

WD-35808-89 Semi-dome, Double-junction, Epoxy-body, Polymer Gel-filled pH Electrode (Use with pH 300, pH 310, pH/CON 300, pH/CON 510 meters) by Oakton

Built-in temperature sensor lets you take ATC readings with a single probe

All-in-One Waterproof electrodes feature a built-in temperature sensor for taking readings with Automatic Temperature Compensation (ATC). Choose a single junction electrode for field, clean water, and general purpose applications. Choose a double junction electrode for most applications, including dirty water, heavy metals and organics applications.

Each electrode is 12 mm dia with a 3 ft cable.

• Includes a FREE electrode saver bottle to extend electrode life
• Feature a BNC connector for pH and a waterproof 6-pin connector for temperature

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

0024-0788 Oxygen Sensor, 2-year by Bacharach

The O2 sensor is used in Bacharach portable combustion analyzers to measure the percentage content of oxygen levels in flue gases. The range of the oxygen sensor is 0 – 20.9%. O2 measurement is used in conjunction with the chosen fuel to calculate the CO2 levels in flue gases. Bacharach portable combustion analyzers only calculate CO2 when oxygen levels are below 16%. Bacharach uses O2 and other readings in determining efficiency rather than CO2 for a more accurate measurement. Measuring oxygen content in the excess air lets you know if you have too much air or too much fuel, allowing you to tune your furnace or boiler to maximum efficiency. Measuring O2 directly can save fuel, and save time during a combustion tune-up test.

• Measures percentage content of oxygen levels in flue gas
• Provides more accurate efficiency readings
• Saves time during tune-ups, telling you if air or fuel is too high
• Available in two year, three year, and five year sensor life depending on instrument
