2194100 Copper Test: Hach Color Disc Free & Total Copper by AquaPhoenix

Copper may exist in natural waters and effluents as a soluble salt or as suspended solids. A small amount is essential for plants and animals, and concentrations exceeding 0.1 mg/L are useful for controlling algae and plankton growth. Quantities ranging from 0.02 to 0.1 mg/L are toxic for some fish, so its use for treating fish disease requires careful monitoring. This kit is USEPA-accepted for waste water and potable water and approved by some states for potable water under specific conditions (Check with your regulatory agency). Range: 0.1-4 mg/L; Contains 50 Free and 50 Total tests.

• Simple, low-cost color disc method is the most accurate visual test kit method
• Kit contains all required reagents and apparatus in a rugged carrying case for analysis in the field

LabSen 821 Glass-body pH Electrode for Dairy Products and Liquid Food by Apera

Backed by proprietary Swiss sensor technologies and materials, the LabSen® 821 Combination pH Electrode/Probe is designed for testing the pH for dairy products such as milk, cream, yogurt, and other liquid food such as mayonnaise, jam, BBQ sauce, syrup, etc.

Silver Ion Trap Reference System+Protelyte Electrolyte - The LabSen® 821 pH Electrode/Probe adopts a Silver Ion Trap reference system and Protelyte reference solution. On top of the Long-Life reference system, a silver ion trap is added to prevent the junction from being blocked or contaminated by proteins.

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).

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors, such as Apera Instruments MP511, PH850, PH8500, PH700, PH910, PH950, 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
• Designed for milk and other liquid food that contain proteins
• Unique LabSen® hemispherical glass membrane, which has a faster response rate, better repeatability, and built tough
• Silver Ion Trap Reference System + Protelyte reference solution, preventing the electrode being contaminated by proteins
• Standard BNC Connector
