Description
Hanna Instruments Refillable, Glass-bodied, Double Junction, Combination pH Electrode with BNC Connector and 1 m Cable, HI1131B
Features:
- General purpose electrode made from high temperature glass to withstand elevated temperature without reducing the life of the electrode — resistance of 400 megaohms @ 25 °C
- Spherical glass tip provides wide sample exposure for fast response times
- Glass body is resistant to many harsh chemicals, easily cleaned, and reaches equilibrium quickly because of fast transfer of heat to the internal reference
- Single ceramic frit with a flow rate of 15-20 μl/hr that has been fused to the glass and has a similar co-efficient of expansion which allows ions to flow freely through the double junction
- Refillable with HI7082 3.5M KCl solution (91-2599-79) — this solution used for double junction refillable electrode contains no silver thus preventing silver precipitates from fouling the junction and causing readings to drift and be erratic
