Product overview
The SL1000 portable parallel analyzer measures a maximum of six parameters at the same time in
drinking water and other clean water applications. The meter uses Chemkeys® and digital
IntelliCAL™ probes to measure different parameters in water. The meter automatically identifies the
type of Chemkey that is installed or the type of probe that is connected to the meter.
The meter can use a maximum of four Chemkeys and a maximum of two probes for measurements.
