HI-981406
HI 981406 has been specially designed for water treatment and swimming pool applications where both pH and ORP (Oxidation Reduction Potential) need to be monitored. Instead of having to source two different meters and worry about wiring and compatibility, you can now continuously measure both pH and ORP with HI 981406.
The HI-981406 has been specially designed for water treatment and swimming pool applications where both pH and ORP need to be monitored. Instead of sourcing two meters, users can now continuously measure both pH and ORP with HI-981406.
There are two separate adjustable set points for pH and ORP. Once the pH set point is exceeded, the appropriate LED light will come on to alert the operator. Likewise, once the ORP level drops below the set point, the red ORP light will stay on.
HI-981406 is supplied with a HI-1283 ground probe. The HI-1283 ground probe provides users with more reliable readouts by suppressing current effects, which are found in pools. The optional HI-2114P/2 pH electrode and HI-3214P/2 ORP electrode are designed specifically for swimming pools. Both probes are constructed with a specially designed fibre salt-bridge making each particularly resistant to clogging in pools.
