Description:
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.
There are two separate set points for pH and ORP which the operator can adjust at will. 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 HI 1283 ground probe. The HI 1283 ground probe provides you with more reliable readouts by suppressing current effects, which are prevalent in pools, from disturbing the measurements. The optional HI 2114P/2 pH electrode and HI 3214P/2 ORP electrode are designed specifically for the swimming pool market. Both probes are constructed with a purpose-built fiber salt-bridge making each particularly resistant to clogging in pools.
