Post-Filter 100 psi Panel RO Gauge


A Post-Filter 100 psi Panel RO (Reverse Osmosis) Gauge is a crucial component in monitoring the performance and ensuring the proper functioning of a reverse osmosis water purification system. Let’s delve into a detailed description:


1. Post-Filter Gauge:

  • Location: Positioned after (post) the RO membrane and any post-filters.
  • Purpose: Monitors the pressure of the water exiting the RO system to ensure it is operating within the desired parameters.

2. 100 psi:

  • Pressure Range: Capable of measuring pressures up to 100 pounds per square inch (psi).
  • Relevance: Adequate for most residential and some commercial RO systems, ensuring safe and efficient operation.

3. Panel Mount:

  • Installation: Designed to be mounted on a panel, typically on the RO system control panel or another accessible area.
  • Accessibility: Allows for easy viewing and monitoring of the pressure gauge during system operation.

Key Components:

A. Pressure Gauge:

  • Measurement: Indicates the pressure of water in the system post-filtration and post-RO membrane.
  • Indicator: Usually features a dial or digital readout to display the pressure level.

B. Panel:

  • Material: Often constructed from durable materials to withstand continuous exposure to water and varying pressure levels.
  • Visibility: Positioned to ensure that the gauge is easily visible and accessible for monitoring and maintenance.


1. System Performance:

  • Monitoring: Regularly checking the post-filter pressure ensures the RO system is performing optimally.
  • Identifying Issues: A deviation from the normal pressure range can indicate issues such as blockages or leaks.

2. Maintenance:

  • Filter Changes: Helps in determining when post-filters may need to be replaced due to increased resistance (pressure).
  • System Checks: Regular pressure checks can be part of routine system maintenance to avoid unexpected issues.

3. Water Quality:

  • Consistency: Ensuring consistent pressure helps in maintaining the quality of the purified water.
  • Safety: Prevents potential damage or leaks by alerting to any over-pressure situations.


  • Residential RO Systems: Ensuring safe and high-quality drinking water for households.
  • Commercial RO Systems: Utilized in various industries, such as food and beverage, to provide purified water for various applications.
  • Aquariums: Ensuring the provision of pure water for aquatic life.
  • Laboratories: Providing consistent and pure water for various experiments and processes.

Installation and Usage:

  • Professional Installation: Engage a professional for installation to ensure accuracy and reliability.
  • Calibration: Ensure the gauge is calibrated accurately for precise pressure readings.
  • Routine Checks: Regularly monitor the gauge and record readings to track system performance over time.


A Post-Filter 100 psi Panel RO Gauge is pivotal in maintaining and monitoring the efficacy and safety of a reverse osmosis system. By providing real-time pressure readings, it allows users to ensure that the system is operating within safe and optimal parameters, thereby safeguarding the quality of the purified water and the longevity of the system.
