Analytic Process Station (3508)
The add-on unit offers an alternative for classes small enough to allow use of the level station as part of the analytic process. The trainer consists of a main water circulation system with a water heater, pump, cartridge type demineralizer, and water reservoir. A variable speed sampling pump draws water from the reservoir and circulates it through a path containing one pH and one conductivity transmitter, then returns it to the reservoir.
The unit features expanded microprocessor-based PID Controller (Foxboro 761), two-pen recorder, pH transmitter, conductivity monitor, one sample pump, two chemical metering pumps, pH and temperature meter, dissolved oxygen meter, temperature transmitter, electric water heater, thermostat control, two chemical reservoirs, piping, and valving.
