The Wallace & Tiernan Products' DepoloxRegistered 3 plus residual analyzer continuously measures free or total (combined) chlorine in drinking water applications. Using universally accepted amperometric measurement technology, the analyzer directly measures chlorine residuals and provides an isolated 4-20 mA output signal for control or recording purposes. Integral alarm relays are included. The analyzer also is available in a dual input arrangement for measuring pH or fluoride, along with chlorine. Using an internally buffered sensor, the analyzer measures total chlorine residuals without the need for reagents. This includes samples with varying pH. For both free and total chlorine, a 3-electrode measuring cell is used. This eliminates the need for constant zero adjustment. Calibration and accuracy are not affected by changes in turbidity or conductivity. The electronic controls and the wetside are separate to simplify installation and provide for operator convenience.

The Model EP960 R.F. Transceiver-Controller from OTEK continuously monitors an input signal and compares it to high and low set points that are 100 percent field-adjustable. It is suitable for monitoring input signals from devices measuring weight, pressure, volume, vacuum, height, depth or other force parameters. The built-in dead band at 2 percent of the setting and the time delay avoid false or transient triggering. When a limit is exceeded, the comparator turns on its alarm LED (red for high, yellow for low), commands the microcontroller to transmit its address and the alarm type to the Master, blinks its "Alarm Transmit" LED and turns on its open collector transistors to control the process.
