Unique Air Quality Meter for the personal protection with datalogger, software and data cable ATEX II 1G EEx ia IIC T4 / ATEX II 2G EEx ia d IIC T4 (EEx ia (d) IIC T3/T4)

This Air Quality Meter is a unique gas meter which protects against a specific gas, inflammable or toxic. The Air Quality Meter Gasman warns with a penetrating alarm and an optical signal (useful in case when there are loud noises in the surroundings) of the existence of dangerous gas concentrations and shows on screen the value of the gas measurement. In addition with this gas meter you are able to save measurements and transmit them onto the computer for evaluation. For that, it is necessary to require the additional option of data logger and optional software. The function of logger will allow you to keep all the values in the meter with a quota of measurement from 1 minute to a total of 900 hours. The data saved in the apparatus can be, at any time, transferred onto the computer or laptop for later evaluation. The Air Quality Meter can be calibrated and certified according to DIN ISO. In addition it is verified according to the most recent directives (94/9/EG and disposition on the protection against explosions (ExVo). Every two years recalibrations can be made where you choose the sensor (according to the type of gas) with which the apparatus must be equipped. You will be able to choose between 12 standard sensors, but you can also request other types of special sensors.
In addition to the traditional uses of the Air Quality Meters such as in industry, institutions and investigations, this gas meter is an economic alternative to be used by the fire brigades (with Ex- sensor for inflammable gases).
The Air Quality Meter fulfills all the European and international norms, even ATEX standards.
Another special use is the measurement of the ozone concentration. For that reason this small Air Quality Meter can be complemented with an ozone sensor
