Plug-n-play TC-80 total chlorine analyser simplifies monitoring, lowers cost

AMS Instrumentation and Calibration has added a new total chlorine
analyser to their product range, designed to simplify water monitoring and
treatment processes for industrial process and municipal engineers.

Recommended for drinking water, process rinse water or cooling water
applications, the new plug-n-play TC-80 total chlorine analyser from
Electro-Chemical Devices (ECD) also reduces ownership costs by lowering the
maintenance requirement.

Highly reliable in performance, the TC-80 analyser monitors total
chlorine content in drinking water, rinse water, cooling water or other fresh
water samples from 0.05 – 20 ppm chlorine as the standard range or 0.005 –
2.000 ppm with the low range sensor.

Key features and advantages of the TC-80 total chlorine analysers
include plug-n-play design enabling easy installation right out of the box; built-in
flow control removing the need for complicated pressure regulators and
rotameters; and built-in automatic pH compensation eliminating the need for
expensive reagents to reduce maintenance and lifecycle costs.

The advanced panel mount design in the TC-80 incorporates a constant head
flow control device, a pH sensor, a chlorine sensor and ECD’s T80
analyser/transmitter conveniently mounted on a PVC panel. The TC-80 is ready to
use by simply connecting the sample and drain lines, and the power and outputs.
The analysers are calibrated in the factory before shipment, with calibration
accomplished by DPD comparison.

Total chlorine is defined as the amount of free chlorine and combined
chlorine in a water sample. Combined chlorine includes chloramines and any
organic or bound chlorine compounds. The TCA sensor is a three-electrode
amperometric sensor with a gold cathode, silver halide anode and 304 SS counter
electrode. The TC-80’s 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.

Amperometric chlorine sensors are flow sensitive – the minimum required
flow by the sensor is 0.5ft/sec, with the output being virtually flow
independent above this value. A ‘constant head’ flow controller maintains the
optimum flow by the sensor over a wide range of incoming sample flow rates. The
minimum flow required is 10 gal/hr and the maximum flow rate is 80 gal/hr with
the sample going to drain at atmospheric pressure.

Available with either 110-240 VAC or 24 VDC power, the TC-80 analyser graphically
displays both the total chlorine and pH values, allowing for easy trend
analysis. The standard configuration has two 4-20 mA outputs and three alarm
relays. An Auto Clean option includes a solenoid actuated spray cleaner using
either 30 psi process water or air. An easily adjusted timer controls the
period and duration of the cleaning cycle.
