PH90 Waterproof
pH Meter
Rugged waterproof (IP57) housing with Flat Surface
Electrode for measuring pH in liquids, semi-solids,
and solids. Does not break or get junctions clogged
like traditional glass bulb electrodes. Easy to replace
sensor is perfect for field or lab use.
Features
• Rugged replaceable flat surface pH electrode for quick
on-the-spot pH measurements
• Simultaneous display of pH and Temperature
• 2 or 3 point calibration automatically recognizes buffer
solutions (order pH buffers separately)
• PTS (percent of slope) tells you when it’s time to
replace your electrode (below 70% or above 130%)
• Automatic Temperature Compensation
• Data Hold, Min/Max, Auto Power Off, and low battery
indication
• Waterproof design (IP57) floats in water and protects
the meter in wet environment
• Complete with flat surface pH electrode, protective
sensor cap, and two 3V CR-2032 button batteries
(pH buffers are required for calibration - sold separately)
