PH Indicator

The pH Indicator which we offer is specially designed for water treatment and swimming pool applications where both pH and ORP need to be monitored. There are two separate adjustable set points in the pH Indicator for pH and ORP. Once the pH set point is exceeded, the appropriate LED light will come on to alert the operator of the pH Indicator. pH Indicator Features :

• LED alarm signals
• Continuous monitoring
• Displays pH and mV simultaneously
• Adjustable set points

About pH Indicator :

• 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 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 fiber salt-bridge making each particularly resistant to clogging in pools.

Order Information : HI 981406-01 (115V) and HI 981406-02 (230V) are supplied with HI 1283 grounding bar, HI 70004 pH 4.01 buffer solution sachet, HI 70007 pH 7.01 buffer solution sachet, calibration screwdriver, 12 VDC adapter and instructions.
