the bulb at all times. During operation, ESD wrist straps should be worn to avoid possible damage
to the electrode by electrostatic discharges.
Any variation introduced by the user to the supplied equipment may degrade the instrument’s
EMC performance.
To avoid electrical shock, do not use this instrument when voltage at the measurement surface
exceeds 24 VAC or 60 VDC. To avoid damage or burns, do not perform any measurement in
microwave ovens.

You can simply install the meter in the vicinity of a pool or the
sample for continuous measurement of both pH and ORP.

The optimal HI 2114P/2 and HI 3214P/2 gel-filled pH and ORP
electrodes are specially made for the pool applications. The BNC
connector is protected behind a waterproof sheath.

You can select your own setpoint and be alerted through flashing
LEDs when the values are outside limits and an intervention is
required. The pH LED blinks when the values are higher than the
setpoint. The ORP LED flashes when the measurements are below
the setpoint.
