Landfill Gas Monitoring for Methane, Hydrogen Sulfide, Carbon Dioxide, Oxygen and Carbon Monoxide

Maximize methane production and protect the power generator from harmful levels of hydrogen sulfide.

Multitec 540

The Sewerin Multitec 540 and Multitec 545 measure 5 common biogases precisely for monitoring or control of biogas processes. Built in infrared sensors measure methane (CH4) and carbon dioxide without errors causes by other gases. Optional electrochemical sensors for oxygen, hydrogen sulfide and carbon monoxide provide more complete monitoring.

Simultaneously measure concentrations of 5 gases: hydrogen sulfide (H₂S), Methane (CH₄), Carbon dioxide (CO₂), Oxygen (O₂), carbon monoxide (CO)
Display: Large 4.3" display with backlight clearly shows all measurements at once even in direct sunlight.
Methane and carbon dioxide measurements are include in all 540 and 545 models. Electro-chemical sensors for hydrogen sulfide, oxygen and carbon monoxide are optional.
Save measurements for convenient transfer by USB port to PC with free software
Certified explosion protection
User friendly large control knob and keys and easy to read screen
Powered by AA rechargeable or disposable batteries
Power: 7 hour battery life, four hour charge time, continuously powered / charged in dock port

Multitec 545

The Sewerin Multitec 545 includes all the other features of the Multitec 540 plus the Multitec 545 measures hydrogen sulfide, H2S up to 5000 ppm while the Multitec 540 measures up to 2000 ppm.

Multitec BioControl 2, 4, 8

The advantages of fixed and portable biogas monitor and control all-in-one portable monitor. The portable Multitec 540 / 545 slides into the docking bay on BioControl 2, 4 or 8 fixed monitoring station. Easily and quickly discount the Multitec 540 / 545 to monitor remote locations, other fixed locators or ship the small unit for maintenance instead of hiring a service technician at much high cost and delay. Instead the much higher cost of having a fixed monitor for each monitoring / control site, simply slide or connect the Sewerin Multitec 540 / 545 into each location. Long sampling lines to remote points of the plant cost a lot to install and introduce errors due to changes during transport to the central monitor site. The flexible portable / fixed Multitec 540 / 545 easily moves to wherever you need it.

Automatically saves all measurements and settings internally with easy copy to USB stick
7" color touch screen
Flexible configuration: Choose measurement locations, cycles, recording intervals, limits, alarms thresholds
Setting history transferred to USP stick
Fixed unit nearly maintenance free. Portable easily removable Multitec 540 / 545 easily shipped for maintenance.
All relevant parts resistance aggressive gases
