Multipurpose Digital Meter SM-01 (SM01)

Product details

Multipurpose Digital Meter SM-01 (SM01) is an electronic conductivity tester used to measure water conditions such as TDS, salinity, and temperature. It applies electronic conductivity measurement to the liquid, converting probe readings into practical values for aquarium water checks. The probe uses a copper body with platinum plating, which is designed to help minimize polarization and support stable readings. For day-to-day aquarium use, this meter is useful when you want a quick, repeatable way to verify salinity/TDS alongside temperature, and when you need a way to calibrate the instrument using the included calibration solution.

Features:

• Large color LCD display for clear readouts
• High-resolution measurement with automatic temperature compensation
• Measures water temperature plus TDS and salinity (and provides specific gravity)
• Manual calibration setting with included calibration solution
• Vibration alarm to indicate test start and completion
• Low-battery reminder function for reliable operation
• Water-resistant build intended for routine testing use
• Conductivity measurement approach designed around probe stability (platinum-plated probe)
