Extech Meters from DropTestKits.com

Built-in Smart chip offers advanced functions and features to a stick style pH meter not found anywhere else.

The only stick style meter with:

• RENEW feature that tells you when it’s time to replace your pH electrode
• CAL feature that tells you when it’s time to recalibrate your meter
• Flat Surface pH electrode that is completely waterproof and rugged enough to withstand harsh environments
• Analog bargraph originates at neutral point (pH 7.00) to conveniently view trends in acidity or alkalinity
• ATC plus measures Temperature
• 1, 2 or 3 point calibration

• Rugged refillable flat surface pH electrode
• Refillable pH electrode that can be reused by refilling the reference solution once it depletes
• Obtains continuous high accuracy using fresh reference solution
• Fast and easy steps to refill your electrode
• Eliminates the concern of electrode shelf life
