Maximize your softener cycle time and minimize your regeneration cost.
The Hach Hach SP 510 Hardness Monitor is reliable, accurate, and virtually maintenance free. It can operate unattended for two months and still promptly and immediately signal hardness breakthrough to activate regeneration. Use it to make water softening systems more eBcient and less costly.
Continuous Hardness Detection
The SP 510 monitor detects hardness breakthrough when the capacity of a water softener is exhausted, immediately signaling the need for regeneration. Alarm points are 0.3, 1, 2, 5, 10, 20, 50, and 100 ppm (expressed as mg/L of CaCO3) and are selected by choosing the appropriate model. Easy to read LED indicators show a simple “HARD” or “SOFT” sample status. You can also use SP 510’s built-in alarm relay to actuate an external annunciator.
Low Maintenance Requirements
The SP 510 samples water every two minutes, operating automatically for up to 60 days. It is virtually maintenancefree, requiring only about 15 minutes every two months to replenish and standardize the reagents. Replace tubing in the pump system every six months.
Convenient, Trouble-Free Operation
The SP 510 monitor makes your water softening system more eBcient and less costly. It eliminates the guesswork so your softener is regenerated only when needed.
Regeneration based on calculation or set times can be replaced with continuous monitoring and automatic control, lowering reagent consumption.
Rugged, Lightweight and Self-Contained
The SP 510 case is made of ABS plastic which is lightweight, corrosion-resistant, and shatterproof. This sealed case is IP62-rated and has a hinged door for easy access to internal components.
