Handheld Odor Meter OMX-SRM / OMX-ADM / OMX-TDM
Handheld Odor Meter OMX-SRM / OMX-ADM / OMX-TDM

Handheld odor meter model OMX, is the most simplified tool for odor analysis, which enables to indicate the relative strength and odor classification numerically by comparing odor gas and purified air. The reading shown on display is calculated based on our original principle.

  • Finding odor source at factories, incinerator plant, or effluent treatment facilities.
  • Evaluation of deodorizing at hospitals or nursing homes etc. 
  • TVOC measurement for monitoring IAQ condition.
Principle of Solid State Realys (SSR)
Principle of Solid State Realys (SSR)

A solid state relay (SSR) is a non-contact semiconductor control component where the input side and output side are isolated like an electromagnetic relay (EMR), and a function which matches the ON/OFF of the input and output is provided for switching electric circuits ON/OFF using semiconductor devices.

Water leakage detection system
Water leakage detection system

Water leak location is electronically measured and digitally displayed at units of 1 meter. Furthermore, when a water leak occurs, the sensor uses a colored display, making an on-site visual confirmation easy and making it possible to identify the location of the leak more quick.
 

Working Principle

  1. Sensor detects water presence or abnormal flow.

  2. Signal sent to controller.

  3. Controller triggers:

    • Alarm

    • SMS/App notification

    • Automatic shut-off valve (optional)

Relief Valve
Relief Valve

Relief Valves are safety devices designed to automatically release excess pressure from a system when it exceeds a preset limit. They help protect equipment, piping, and personnel by preventing overpressure conditions, ensuring safe, stable, and reliable operation in industrial and process applications.
