Vernier™ Go Direct™ Calcium Ion-Selective Electrode

Description

• Range (concentration): 1 to 40,000 mg/L (or ppm) Interfering ions: Pb 2+ , Hg 2+ , Si 2+ , Cu 2+ , Ni 2+ , NH 3 , Na + , Li + , K + , Ba 2+ , Zn 2+ , Mg 2+ pH range: 2 to 8 (no pH compensation) Electrode slope: 26 ±2 mV/decade at 25°C Electrode resistance: 100 MΩ Minimum sample size: must be submerged 2.8 cm (1.1 in.) Includes: Go Direct ISE Amplifier attached to a Go Direct Calcium Ion-Selective Electrode BNC Micro USB cable 30 mL bottle of High Standard solution with SDS (1000 mg/L Ca 2+ ) 30 mL bottle of Low Standard solution with SDS (10 mg/L Ca 2+ ) Short-Term ISE Soaking Bottle Robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly Data from the wireless Go Direct Calcium Ion-Selective Electrode can give a good indication of the hardness of water
• The concentration of calcium is also used as an endpoint indicator in EDTA-Ca/Mg hard water titrations
• The versatile BNC connector allows students to easily replace the electrode when it expires or becomes damaged
• You need only replace the electrode and not the entire sensor—lowering your overall equipment costs
• Has a combination-style, non-refillable, gel-filled electrode.
