Developed for the electrical industry, the SRX3 is a self-powered, multi-channel data logger that can monitor and record up to 7 separate inputs.  These 5V inputs can be paired with voltage and current transducers to record 3-phase AC power delivered to a load.  Includes TRX Basic software and Mini USB interface cable.

Typical applications include:

  • Energy baseline studies
  • Determine energy consumption
  • Conduct start-up or long-term load analysis
  • Compressor monitoring

Key Features:

  • Connect to a wide range of sensors to deliver a customized integrated solution with outstanding functionality
  • Capable of storing up to 1 million readings
  • LED flashing alarm lights
  • Two-stage alarming (Warning & Critical)
  • 16-bit resolution provides greater precision
  • Can be calibrated to NIST standards to achieve the highest possible measurement accuracy
  • Portable equations onboard the data logger ensure faster downloads and collaboration with less user intervention
  • One-button report generation
  • Wizards for Custom Equations and logger configuration for ease of use

Data loggers are often used in highly regulated environments such as food and pharmaceutical production and storage where strict safety regulations apply. Regulatory agencies generally require proof of calibration.

ACR calibrations are performed using reference standards that have been calibrated and are traceable to the US National Institute of Standards & Technology (NIST). This ensures that all ACR data loggers meet, and perform to, their published specifications, allowing you to be confident that they will assist you in achieving your compliance requirements.

Calibration certificates are provided with every calibration we perform. ACR Systems is an ISO 9001:2015 registered company and calibration records are kept as part of our quality system and can be made available for customer audits.
