TRM-1

The TRM-1: Triple In-Line TDS Monitor by HM Digital is an advanced device designed to measure Total Dissolved Solids (TDS) in water. TDS represents the dissolved substances, including salts, minerals, and organic materials, which impact water quality. Elevated TDS levels can affect the suitability of water for drinking, industrial applications, or specialized processes. The TRM-1 offers the advantage of monitoring TDS levels at three distinct points, such as within Deionization (DI) or Reverse Osmosis (RO) systems.

Key Features:

• Triple Point Monitoring: Provides TDS readings from three sensing points, ensuring comprehensive water quality assessment across various stages of filtration.
• Accurate and Efficient: Utilizes advanced microprocessor technology for precise and reliable readings.
• Auto-Off Function: Automatically shuts off the monitor after 10 minutes of inactivity to conserve battery life.
• Dual Range Display: Measures TDS from 0 to 9990 ppm, with a resolution of 1 ppm for values up to 999 ppm, and 10 ppm for values between 1000 and 9990 ppm, indicated by a blinking 'x10' image.
• Factory Calibration: Pre-calibrated with a 342 ppm NaCl solution, and can be recalibrated using a mini-screwdriver.
• Multiple Fitting Options: Includes three 1/4" T-fittings, with optional 3/8" or 1/2" fittings available.
