MAP Check 3 Online Gas Analyser / Flow Control

For real time, continuous monitoring of headspace O2 + CO2 in food packages as the products are being packed on bagging and flow wrap packaging equipment. Includes online oxygen gas analyser (CO2 sensor available optionally), GasSave to optimize gas useage, logs & displays actual gas consumption and interfaces with Dansensor MAP Mix Provectus gas mixer.

Dansensor MAP Check 3 Online Gas Analyser / Flow Control

With the Dansensor MAP Check 3, the gas target you set is the gas dosage you get, removing the problem of operators using too much gas without realising the effect it has on production costs.

The Dansensor MAP Check 3 increases your flexibility enabling you to combine monitoring of gas content on a vertical or horizontal flow packaging machine with real time control of package flushing via an enhanced GasSave function. For most manufacturers that translates into 20 – 50% decrease in gas consumption.

It also improves reliability and efficiency. Unlike off-line quality control, the on-line quality assurance of the Dansensor MAP Check 3 means that every package is tested – far quicker and more efficiently than with manual testing. And if there is a problem, production stops automatically, helping to avoid recalls or the need to re-pack entire batches.

Dansensor MAP Check 3 Pressure & Dansensor MAP Check 3 Vacuum

The MAP Check 3 Pressure is also as available as a special unit for measuring pressurised gases and the MAP Check 3 Vacuum for use on thermoform & tray sealing MAP food packing machines.

The Dansensor MAP Check 3 replaces the MAP Check Combi II – PFC and when combined with the MAP Mix Provectus they together
supersede the TGC-2.

  • Logs and displays actual gas consumption for easy traceability with GasSave function
  • Reduces labour and waste costs compared with manual testing
  • Avoids recalls / re-packaging by stopping packaging machine if the machine exceeds preset limits
  • Reduces work area CO2 levels to protect employees
  • Reduce waste & recalls, MAP Check 3 will automatically stop the packaging machine if the pack residual oxygen is out of tolerance.
  • New management information for better control of total gas consumed, pack residual oxygen and current gas flow
  • Get total control via a single touch screen when the MAP Mix Provectus and the MAP Check 3 are linked together
  • Easy traceable evidence of pack residual oxygen content and gas consumption through data download


  • 5″ colour touch screen
  • Improved data logging capabilities with USB, Ethernet, TCP Modbus
  • Ability to control MAP Mix Provectus gas mixer
  • Delivered with PC software
  • 3-channel multiplexer
