(com-80) premier testing instruments

Description

The COM-80 EC/TDS Hydrotester is an advanced and economical device ideal for measuring Electrical Conductivity (EC) and Total Dissolved Solids (TDS) in various applications such as hydroponics, gardening, aquariums, drinking water, and more. It’s designed for precision, ease of use, and durability.

Key Features:

1. Multi-Measurement Capability:
   • Measures EC and TDS, making it versatile for testing water quality.
   • It supports four modes: EC in µS and mS, TDS in ppm (using both NaCl and 442™ scales).
2. Automatic Temperature Compensation (ATC):
   • Ensures accurate readings despite fluctuations in temperature.
3. Waterproof Design:
   • The device is waterproof, making it highly durable and suitable for harsh environments.
4. Digital Calibration:
   • Features easy push-button calibration for accurate results.
5. Data Hold & Auto-Off Function:
   • Includes data hold to freeze readings and an automatic shutoff to save battery.
6. Large LCD Display:
   • Provides clear readings for both the main measurement and temperature.
7. Factory-Calibrated:
   • Pre-calibrated with a 1413 µS solution but can be recalibrated by the user.
