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.

• 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

90550-93 Dampen Bottom-Con Bimetal Thermometer 5" Dial 24" L Range 0-250F (-20-120C) by Digi-Sense

Accuracy is ±1% full-scale when stem is immersed 2" in liquids or 4" in gases (immerse models with a 2.5" stem length 2" in gases). Measured stem length from the top of the threads to the bottom tip of the stem. Stem dia is 0.25"; threaded connection is 1/2" NPT(M). All thermometers meet or exceed ASME B40.3 standards. Maximum environmental temperature for glass lens thermometers is 500°F (148°C).

• Dampened movement
• More economical than silicone gauges
• Greater temperature range than a silicone-filled gauges
• Anti-parallax dial for accurate readings
• Eliminate the risk of a leaking case and cross-contamination
• Rugged 304 stainless steel construction with a clear glass lens
• Recalibrate using the external reset screw
• Hermetically sealed per ASME B40.3 standard to prevent fogging and protect against tough environments
