LabSen 881 Glass-body pH Electrode for Low Temperature Solutions by Apera

Backed by proprietary Swiss sensor technology and materials, the LabSen® 881 Glass Combination pH Electrode is ideal for pH measurements for low-temperature solutions (down to -22 °F).

Special Glass Membrane - The LabSen 881 pH electrode adopts a low-impedance glass membrane, which is especially suitable for low-temperature sample testing. The conical sensor tip is highly resistant to general impact (completely different from the traditional fragile glass bulb sensor), and has a faster response rate and better repeatability.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors, such as Apera Instruments MP511, PH8500, PH850, PH700, PH800, PC800, PH820, and PC820. The temperature sensor is not 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.

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

• Proprietary pH sensor technology and materials from Switzerland
• A special low-impedance glass membrane is adopted, which is especially suitable for low-temperature sample testing
• LabSen conical sensor tip - fast response rate, high repeatability, and built tough
• Standard BNC Connector
• 6-Month Warranty fulfilled by Apera Instruments

90447-41 Standard RTD, Mini-Plug, 1/8" OD, 9" L, Adjustable Compression by Digi-Sense

Resistance Temperature Detectors, or RTDs, are used in many process and laboratory applications where accuracy and repeatability are of prime importance. RTD elements are available in many different materials and with different temperature coefficients. The most commonly used element is a wire-wound platinum element, conforming to the DIN standard and with a .00385 temperature coefficient.

Key Features

• 316 stainless steel sheath material
• Extension leadwire transition with relief spring (350,°F)
• 3-wire RTD, 100 Ω
• Accuracy ±0.1%
• -328 to 400°F (-200 to 204°C)
• .00385°C temperature coefficient

93831-97 RTD Probe, 100 Ohm, ANSI 3-Blade Connector, 9" L, 3ft SS Braid Cable by Digi-Sense

Maximum error for probe assembly is ±1.1°C + 0.12% of reading below 300°F, ±0.35% of reading above 300°F. Alpha coefficient is 0.003850 Ω/Ω/°C (DIN IEC 751). Resistance at ice point (0°C) is 100 Ω.

Note: Time constant is the time required to reach 63.2% of the new reading. To determine how long it will take to reach 99% of the new reading multiply the time constant by five.

Note: The temperature range is for the probe tip only. The handle material may be affected if the probe is rated higher than the handle depending on exposure time, application, and handle material. ABS handles are rated to 220°F (104°C); PVC handles are rated to 200°F (93°C); Stainless Steel handles are rated at 450°F (232°C); Mini Connectors are rated to 392°F (200°C).

• Time Constant: 1-3 seconds or greater
• Custom designs or changes to this product are available upon request
