Easy, Economical Total Chlorine Measurement With Highly Intelligent ECD TC80 Analyzer

April 2024

ECD’s intelligent TC80 Analyzer eliminates consumables, simplifies installation and reduces maintenance with a self-cleaning design to lower the total cost of instrument ownership over its long life. This versatile, easy-to-use analyzer is a panel-mounted unit that is ready-to-go right out of the box. It is also fully compliant with the U.S. Environmental Protection Agency’s (EPA) Method 334.0. 

Ideal for measuring total chlorine, the TC80 Analyzer’s Cl2 sensor is a precision three-electrode amperometric type design, which measures all chlorine species in the water, combined chlorine and free chlorine. It is available in either: (1) a standard high-range configuration measuring Cl2 from 0.05 to 20 ppm or (2) a standard low-range configuration of 0.005 to 2.000 ppm. This analyzer comes factory pre-calibrated to the chosen measurement range before shipment, which also speeds set-up.

Total chlorine is defined as the combined amount of free chlorine, chloramine, organic and bound chlorine in a water sample. The TC80’s Cl2 sensor is a three-electrode amperometric sensor with a gold cathode, silver halide anode and 304 SS counter electrode. The TC80’s built-in pH sensor provides accurate compensation for samples between pH 4 and pH 12, eliminating the need for expensive sample conditioning systems to control the pH of the solution.

The TC80 Cl2 Analyzer is a complete solution requiring no additional third-party components.  Everything needed comes in one box from ECD and is assembled on a panel mount board.  The plumb-plug-and-play design incorporates a flow control device, the pH sensor, the chlorine sensor and the highly intelligent T80 transmitter, which are all conveniently mounted on the instrument’s ready-to-mount PVC panel.

Installation is simple: There is no special technician training or tools required for installing the TC80 Cl2 Analyzer.  Technicians simply connect the sample and drain lines, connect the power and outputs and the analyzer is ready to use.  The analyzer’s amperometric sensor technology and automatic pH compensation keep the cost of ownership low by requiring no inventory of expensive reagents on a shelf, tracking/ordering of reagents or valuable technician labor time to replace them.

Featuring an automatic flow control and large flow tubes and cells, the TC80 Analyzer greatly reduces clogs and blockages, which are a common problem in other total chlorine analyzers and allows for easy cleaning. It also can be ordered with an auto cleaning option to keep the chlorine sensor clean from water contaminants for an extended period of time.  This useful time scheduled pressure-spray washer keeps particles from adhering and building up on the sensor.

For user flexibility, the TC80 Cl2 Analyzer is available with either 110-240 VAC or 24 VDC power. The TC80 graphically displays both the total chlorine and pH levels, which supports easy trend analysis. The standard configuration has two 4-20 mA outputs and three alarm relays, 24 VDC or 110/220 AC power. 

TCV80 Analyzer users will appreciate the choice of MODBUS and/or HART communication that is available when ordering.  Both digital bus communication options report Cl2 analysis data directly to automated process control systems that can adjust Cl2 levels in the process stream according to real-time conditions.
