4210B10
- Optimal temperature range: 0 - 40°C
Constructed with a clog-free Sure-Flow junction. Includes 60 mL of refill solution. Uses easily replaceable 4210B03 plastic membrane module.
4210B13
- Highly selective for calcium over other divalent cations
Polymer-membrane electrode measures calcium in aqueous solutions from 40,100 down to 0.02 ppm as calcium over optimal temperature range 0-40°C. Uses include calcium in soils, fertilizers, feeds and plant tissues or calcium in boiler feed waters. Requires reference electrode 4215F10.
Reference fill solutions: 4210B10 uses Optimum Results A filling solution (Thomas number 4209N38); 4210B13 uses 4 N KCl saturated with Ag (Thomas Number 4153H44)
Accessories:
- Calcium Standard: 4210B35 contains calcium chloride in molar concentration of 0.1000 ±0.0005.
