Product Description
Professional Waterproof Conductivity Pen for EC & TDS TestingThe Milwaukee C65 is a rugged, waterproof conductivity pen designed for accurate EC (electrical conductivity) and TDS (total dissolved solids) measurement in aquariums, hydroponics, pools, and water quality applications. With automatic temperature compensation (ATC) and a replaceable electrode, this portable tester delivers reliable readings in any environment.Key Features:
Waterproof Design: IP67-rated protection allows testing in wet environments and withstands accidental submersion
Dual Measurement: Measures both EC (0-1990 µS/cm) and TDS (0-995 ppm) with the push of a button
Automatic Temperature Compensation (ATC): Built-in sensor ensures accurate readings from 32 to 122°F (0 to 50°C)
Replaceable Electrode: MA830R electrode can be replaced for long-term use and cost-effective maintenance
Easy Calibration: Simple one-point calibration with 1413 µS/cm solution for optimal accuracy
Portable & Convenient: Compact pen design fits in your pocket for on-the-go testing
