GAS DETECTION - TOXIC, OZONE - PORTABLE

Ozone Monitoring
AP's strength in ozone has allowed us to solve numerous measurement challenges in the ozone industry where the ways in which ozone is being beneficially applied are many and constantly evolving.

In ozone health and safety monitoring or industrial process control of ozone generators, our meters, monitors and controllers have the sensing technology and features needed to consistently deliver to your requirements.

Current sophisticated, expensive ambient air pollution monitoring technology is not economically sustainable as the sole approach and cannot keep up with current needs, specifically new monitoring networks and special purpose monitoring.

Measuring ozone toxicity
The detectors measure the ambient ozone levels in commercial kitchens, water and sewage treatment plants, homes and industries in a variety of safety related applications.

Ozone is used in many industrial processes and in commercial buildings.

It has become increasingly important to measure ozone around ozone generators, air purifying units, electrostatic filters, systems for needle ionization and tube ionization, systems emitting UV radiation as well as other types of installations that produce ozone.

The ozone detector is used to protect and alert people for exposure from ozone and to abide with the requirements of the Swedish Work Environment Authority. Threshold level is 0,1ppm = 0.2 mg/m³ (exposure limit value for a working day) and maximum threshold is 0,3ppm = 0.6 mg/m³ (exposure limit for a reference period of 15 minutes).

The detector is also used to detect leaks and to provide automatic control of various processes and equipment.

In the US, the exposure limit is 0,05ppm (50ppb), which is recommended as an critical alarm.
O₃ -detectors from Automatikprodukter are intended for early detection of ozone, measurements and control of the air, including process ozones (high levels), ambient ozones (low levels) and flue gas zones (low concentrations).

This is a long-term requirements of the WHO (World Health Organisation), as exposure limit for ozone. Some OVK controllers set their own emission limits for ozone at a maximum of 0.04 ppm (ie 40 ppb).

The measurement should be carried out about 0.3 m above the floor since it is a heavy gas with a specific density of 1.7. The density of air is 1.0
  
The detector requires no further calibration by a qualified technician.

Ozone is a toxic gas. Many Europeans will die of diseases triggered by rising concentrations of ground-level ozone in the next years.

The human nose is not sensitive enough to detect the metallic smell from ozone.

Our sense of smell also varies greatly between people and can be influenced by local environmental conditions.

Checking required health and safety standards

Gas Sensor Specification

Electrochemical ozone sensor for fast response
Our EOZ sensor (0-10ppm) incorporates a Kalman filter and advanced signal processing to give excellent linearity across the entire range.

The screen updates every 4 seconds making this sensor an excellent choice for leak detection and health and safety monitoring where the user is moving quickly between locations.

Because the sensors can be swapped in and out – one portable monitor can harness both ozone sensor technologies in the same device.

PS 200 - Ozone Meter
PS 200 portable is a monitor compatible with different ozone sensors as well as a temperature and humidity sensor, if required.

It is an entry level device designed for spot checking ozone concentrations in a variety of applications.

The display can be configured to show the real-time ozone concentration or to display the minimum, maximum and average readings.

Ozone concentrations can be displayed in either ppm or mg/m³.

The meter is also supplied with a long life lithium battery which has over 8 hours of battery life and a recharge time of 2 hours.

PS 200 can be fitted with any of the sensor heads listed in the table above.

Because the calibration data is stored in the sensor head, the process of swapping sensor heads is extremely quick and can be done by anyone anywhere.

It also makes recalibration and servicing easy – simply return the sensor head to AP or purchase a new one.

The Ozone meter also has an inbuilt option to zero calibrate the installed sensor head to maintain data accuracy between recalibration intervals.

Features

• Very easy to use

• Fits comfortably in the hand

• One meter compatible with ozone sensors

• Changing sensors takes seconds and can be done anywhere

• Remote sensor capability

• To recalibrate simply send the sensor back to AP

• Long life lithium battery technology

• Large display gives min., max. and average readings

 PS 200

PS 300 - Ozone Monitor with alarm and control functions. In addition to the functions of  PS 200 there are the following functions.

There are user defined high and low alarm set points which will trigger an audible alarm when the ozone concentration exceeds the set point.

A key feature of  PS 300 Portable Ozone Monitor is the ability to operate in control mode.

Upper and lower control limits can be easily set directly on the display.

Using the 0-5V output the  PS 300 can be used to switch on or off an externally connected device, such as an ozone generator, or system in the presence of a predetermined level of gas.

By selecting the optional wall-mount bracket and plugging in mains power  PS 300 is effectively able to act as a fixed monitor as well as a handheld portable device.

For those wanting to recalibrate in the field, 
PS 300 allows adjustment of zero and span.

 Together with the R42 Calibration Accessory and an ozone generator this function allows the sensor head to be fully recalibrated without having to return it to AP.

Alternatively the sensor head can be returned to AP for a factory calibration which includes a renewed calibration certificate.

Features

• Audible alarm to notify ozone exceedences

• Analogue output to control external devices e.g. ozone generator

 PS 300

PS 500 - Ozone Analyzer, data logging
In addition to the functions of  PS 300,  PS 500 features the following functions.

PS 500 portable ozone analyzer enables accurate real-time measurement of ozone.

Data is stored on board the PS 500 with a maximum 8,188 records available. To download the data a USB cable is supplied for connection to PC.

Free PC software provided with the PS 500 takes the data and presents it in a chart or table view. Data can be downloaded and viewed in Excel.

Other features on the PS 500 include monitor ID and location ID.

Monitor ID identifies the analyzer uniquely and ensures that all data from it are tied to that monitor.

ID can be used to tag measurements to a specific location which is helpful when sampling at a number of sites over the course of a day or week.

High and low alarms can also be configured to alert when ozone concentrations have reach a user defined set point.

Features

• Data logged directly onto monitor base

• Audible alarm functionality

• Zero and span calibrate in the field

• Free PC software (Windows 7, 8, XP compatible)

• Connect direct to PC via USB

Calibration
The Calibration Accessory is a simple and effective tool for calibrating sensor heads for handheld and fixed monitors.

By delivering a consistent flow of calibration gas to the sensor head, without forcing air at the sensor, it ensures the most accurate calibration possible.

The calibration tool can also be used to humidify the gas which is important for best results with GSS sensors.

Further information on how to calibrate sensor heads can be found in the pdf to the right.
