Dissolved Ozone Sensor Monitor

EZ-10W Measures dissolved ozone in water samples. This is a portable analyzer, battery operated instrument for taking water samples only. A use 50-180 ML samples and it does not come in contact with the water. It has many applications in bottled water, swimming pools and spas, water treatment systems, aquariums, food washing and canning, wine making, cooling towers, research and much more.

EZ-10W is used to measure dissolved ozone in samples taken from the process water. This new instrument is very popular because it is low in cost and does not require consumable reagent chemicals.

We recommend its use only for water with low ozone demand however so that the dissolved ozone concentration does not decrease during the sampling process. Bottled water residual and ozone in process water and wash water are examples of good applications.

Waste water and water with bromine compounds are not good applications.

RAP-2 The model RAP-2 is a remote alarm panel for gas and other detection instruments. It is designed to work with various Eco Sensors instruments including the C-21, C-30ZX, EE-1, EE-2, OS-1X, OS-3, OEM-1, and OEM-2. The RAP-2 can alarm by detection of closed relay contacts, signals exceeding DC voltage in put thresholds and signals exceeding 4-20mA current in put thresholds. The alarm is in the type of a flashing red strobe lamp and a pulsating audio alarm which can be turned off by its Acknowledge switch. When the alarm is activated a relay with both normally open and normally closed contacts is activated. The RAP-2 can be located many hundreds of feet or meters from the gas instruments if the connection wiring is has minimum loss and there is no outside signal interference.

UV-100 OZONE ANALYZER

The Eco Sensors model UV-100 ozone analyzer is for general purpose measurement of ozone in air. Its range is .002-100 ppm (v) with 2% accuracy, and it includes a built-in data logger. The UV-100 weighs only 2.1 kg (4.7 lb), it is powered by an AC adapter or 12 V external battery, and is equally versatile for the laboratory or for process monitoring. The outputs are digital display, 0-2.5VDC and 4-20mA. The instrument features LEDs to indicate calibration is due, the sample line filter should be replaced, and that the sampling area is above the danger limit of .1 ppm. Recalibration and annual maintenance is immediate simply by a factory service rep exchanging the pre-calibrated sensor module.

NOTE! 1. All Eco Sensors products are designed and sold as sensors and monitors for indoor use due to interference from atmospheric gases and other reasons.

NOTE! 2. For refrigerated cooler applications or sensing colder environments. The sensor or switch would be mounted outside of the cooler in a warmer environment. An aquarium air compressor can be used to suck the air from the colder environment thru 20 to 30 feet of coiled tubing. This allows the air to warm up within the indoor temperature range. At the end of the tubing you would connect a tee with the branch of the tee fitting connected to the sensor air inlet, the outlet of the tee fitting would connect to the air inlet of the mini compressor.
