Total Free Chlorine & pH 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.

Description

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 Program Does What You Expect

  • Self- and sensor diagnostics
  • Fault tolerant
  • Output hold during calibration
  • Two programmable 4-20 mA outputs
  • Dual programmable alarms with self- and sensor alert
  • Frequent adjustments by keypad prompts
  • Program remembers what you were doing
  • No long key sequences
  • Instant return to sample display
  • 3-Level security to protect settings
  • Easy to operate
  • LCD displays ppm chlorine, pH, temperature, alarm setpoints, and calibration status.

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

The analyzer is 115/230 VAC operated.

IC Controls has incorporated intelligence into the microprocessor analyzers, which can be accessed using the optional IC Net™ 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 Net™ Intelligence Access Program runs in your Windows-based computer using RS485/RS232 and can provide you access to multiple analyzers.
