Chemkeys – Reagents for SL1000

Use Hach's Patented Chemkey™ Technology with the SL1000 Portable Parallel Analyzer (PPA) for dramatically streamlined water quality testing. 

Chemkeys are a new technology from Hach that are designed for use with the SL1000-PPA Portable Parallel Analyzer.

Same Trusted Technology: Chemkey reagents execute the same process steps that you have trusted for decades — now delivered in a simple, self-contained package. All chemicals and processes are entirety contained inside the Chemkey. 
Less Hassle: There is no zeroing, no mixing, no shaking, no chemicals or vials to handle. All you have to do is insert the chemkey and let the PPA-SL1000 read you back the results. 
Increasing Portfolio: So far, we have released Chemkeys in 3 different phases. We initially released our Phase I Chemkeys which are: monochloramine, free and total ammonia, free and total chlorine, nitrite, copper. The following Phase II Chemkeys have been released: orthophosphate, hardness, alkalinity, and dissolved iron. Phase III parameters include: Extended range chlorine (up to 10mg/L), Combined Free and Total Ammonia (two measurements, one chemkey), and High Range Hardness.
