COM-100 Professional EC/TDS/Temp Meter

The COM-100 is a professional-grade meter designed for precise water quality testing across a wide range of applications. From hydroponics and aquaculture to pools, labs, and water treatment systems, this versatile meter ensures accurate readings of electrical conductivity (EC), total dissolved solids (TDS), salinity, and temperature. Its durable waterproof design and replaceable probe make it a long-lasting tool for growers, technicians, and researchers alike.

Features

• Multi-Parameter Testing: Measures EC, TDS, salinity, and temperature in one compact device.

• Automatic Temperature Compensation (ATC): Ensures accurate readings across variable water temperatures using three selectable coefficients.

• Waterproof Housing (IP-67): Submersible and floats for worry-free use in demanding environments.

• Digital Calibration: Push-button calibration to any point within the meter’s range for ultimate precision.

• User-Friendly Display: Large, easy-to-read LCD screen with simultaneous temperature readings.

• Replaceable Sensor: Detachable platinum electrode probe (SP-C1) extends the life of the meter.

• Smart Functions: Auto-off, data hold, and low-battery indicator improve usability and efficiency.

• Factory Calibrated: Pre-calibrated with a 1413 µS solution for immediate use.

• Aquaculture: Ensure safe and balanced water conditions for fish and aquatic life.

• Water Purification & Treatment: Test and verify filtration or treatment system performance.

• Pools & Spas: Quickly assess salinity and water balance for safe recreation.

• Scientific & Lab Testing: Trusted for accuracy in ecology, environmental monitoring, and research applications.

How to Use

1. Turn on the meter and immerse the probe in the solution you wish to test.

2. Allow the reading to stabilize; results for EC, TDS, salinity, and temperature appear clearly on the display.

3. Calibrate when necessary by using the digital push-button function with a known calibration solution.

4. Rinse and store properly after each use to extend probe life.
