LM 3189 is the most cost-effective dust monitor model, equipped with a semiconductor laser. It is excellent for measuring at the medium to long distances( 3 - 10 m) and medium high concetrations. ( > 25 mg/m3).

Advanced dust monitor with semiconductor laser. There is a model LM 3189 AZH available as well which is suitable for dust contents up to 20 g/m3 but otherwise offers the same features as LM 3189 AZL.

LM 3086 EPA3 offers the new performance standard in opacity/dust monitoring. It fulfills the U.S EPA 40 CFR Appendix B, PS1 requirements and is also approved by TÜV for German 13th BlmSchV and TA Luft.

LM 3086 SE offers the new performance standard in opacity/dust monitoring which is based on the model designed for USA-market and approved by US EPA. LM 3086 SE has TÜV approval for German 13th BlmSchV and TA Luft.

The filter controller consists of an isolated probe which is installed in the clean gas channel. The complete electronic is integrated in the probe head. No additional control unit is required. The charge transferred by contact and triboelectric processes is derived as current, converted in the evaluation unit, amplified and provided as norm signal 4 ... 20 mA. Via a limit value detector the exceeding of the allowable emission limit value can be signalised optically or acoustically.

The device is simple in construction and very user-friendly. The integrated micro-controller allows numerous possibilities to use the PFM 02 as well as a timely monitoring of the dust emissions. Target value calibration: Enter a known, averaged dust content in operation state - The PFM 02 determines automatically appropriate calibration factors and shows the quantitative dust content in mg/m³.

The dust concentration measuring device PFM 02 V is used for the continuous measurement of dust contents, especially for the emission measurement according to TI air, 13th, 17th and 27th BImSchV as well as for the dust concentration measurement in process monitorings. Parallel to the dust measurement flow and temperature of the smoke gas are registered (in combination e.g. with FMD 02).

The dust concentration measuring device PFM 97 W is used for the continuous measurement of dust contents, especially for the emission measurement according to TI air, 13th, 17th and 27th BImSchV as well as for the dust concentration measurement in process monitorings. Parallel to the dust measurement flow and temperature of the smoke gas are registered.

The dust concentration measuring device PFM 97 ED is used for the continuous extractive measurement of dust contents in wet and sticky exhaust gases. By means of a temperature-regulated probe the measuring gas is extracted from the process and led to the measuring chamber where the triboelectric dust sensors are placed.

The GMD 12 is an intelligent system for isokinetic dust and particulate matter measurements in exhaust gas stacks and channels. These gravimetric dust measurements are used for reference measurements to calibrate dust measuring devices. The GMD 12 is able to record independently all parameters being necessary for the dust measurement (e.g. humidity of the measuring gas, velocity in the exhaust gas channel as well as temperature and pressure).
