876-25 Total Free Chlorine & pH Method Analyzer with Sample Panel

876-25 Total Free Chlorine & pH Method Analyzer with Sample Panel

The industrial total free chlorine analyzer and sample panel model 876-25 from IC Controls give you maximum flexibility, reliability, and ease of use.

Sample Panel Features

  • No reagents required
  • Includes two separate loops: total free chlorine and pH
  • Two chlorine readouts: total free chlorine and free available chlorine
  • Sample panel includes chlorine sensor, pH sensor, flow cell, pressure-reducing valve, flow setting valve, atmospheric break, constant head, grab sample point, and atmospheric drain
  • Sample-conditioning panel assures good results

Easy Maintenance

  • No reagents are required to measure total free chlorine
  • Chlorine membrane module replacement is easy
  • Reliable, separately powered and optically isolated output circuit prevents computer interface problems
  • Alignment controls hidden, but accessible when needed
  • Durable housing withstands hosing down, survives acid and caustic fumes, rain, and humidity.

IC Controls has incorporated intelligence into the microprocessor analyzers, which can be accessed using the optional IC Netâ„¢ Advanced Intelligence Access Program. Measurements such as chlorine can be critical to your process and must be strictly monitored and maintained. Analyzer intelligence goes beyond measurement and control; it provides the user with all necessary historical data, including events such as calibrations and diagnostics. This information can be communicated for trending or advanced control, even to remote locations. Ultimately, the user has superior control with a competitive advantage.

The analyzer stores the last 12 monthly calibration records. The last 20 upsets are recorded and date-stamped, e.g. out of spec events, alarms and power interruptions. Internal data logging capability can record hundreds of data points at user-defined time intervals for later recall of factors leading to alarm conditions and for analyzing measurement trends. An optional real-time clock allows accurate tagging of events and duration even through power outages.

The IC Netâ„¢ Intelligence Access Program runs in your Windows-based computer using RS485/RS232 and can provide you access to multiple analyzers.
