This SHIMANA Carbon Monoxide Meter detects the presence of carbon monoxide (CO) and measures concentrations between 1-1000 parts per million (PPM). The SHSEGA078 Gas Detector Meter indicates the presence of CO by a reading on the LCD and a beeper tone. The beeper function much like clicking of a Geiger counter: above 200 PPM, the beeper sounds continuously with the concentration of CO; from 35 PPM to 200 PPM, the beeper sounds discontinuously with the concentration of CO.



Common sources of potentially dangerous levels of CO are:

  • Poorly maintained furnaces, gas heaters, or fireplaces.
  • Dirty or plugged chimneys, or flue exhausts.
  • Poorly maintained gas, oil, or kerosene appliances.
  • Internal combustion engines (e.g., automobiles, lawnmowers, blowers).

Not what you were looking for? We carry other gas detectors too: Refrigerant Leak Detectors (for CFCs, HCFCs & HFCs gases), Combustible Gas Leak Detectors (for a wide variety of gases: natural gas, propane, butane, methane, acetone, alcohol, ammonia, steam, carbon monoxide, gasoline and many others) or simple Flammable Gas Leak Detectors (for small gas containers such as lighters or camping-gas containers).

This portable carbon monoxide meter is a highly accurate instrument with an extremely fast response time - critical factors when measuring CO concentrations. You can buy this CO meter as well as other gas detector from your Canadian distributor, DMM. Please do not use the Meter as a personal safety monitor.

Need to have this new Shimana SHSEGA078 Carbon Monoxide Gas Detector calibrated? While this gauge has passed a quality control check, having a calibration certificate for gas detectors might be required by your quality control system. Digital Measurement Metrology (owner of is a canadian metrology company with more than 25 years of experience. Our Brampton, Ontario based calibration lab has one of the most comprehensive ISO 17025 accredited calibration scope in Canada.

Do you have an old Shimana gauge to be calibrated? We might be able to calibrate Shimana gas detectors (Shimana SHSEGA078 or a different model) and provide an ISO, NIST traceable calibration certificate. Please contact our metrology lab for more info.
