Gas Monitoring Systems

PureAire vs. Det-tronics

The following information demonstrates a cost of ownership comparison of Det-tronics disposable electrochemical monitors and PureAire’s renewable sensor cell. Detronics H2S recommends calibration after 24 hours initial power-up, one week later and every 30 days thereafter, or as determined by the needs of the specific application 1. Det-tronics also suggests a visual inspection of the detector approximately once per week is recommended to ensure that physical obstructions such as trash, debris, mud, snow, or oil have not blocked or impeded hazardous gas access to the sensor.1 Detronics H2S monitor includes visually inspecting the hydrophobic filter on the detector nosepiece.1

Det-tronics Infiniti Gas Transmitter instructions mentions the operator should frequently inspect the hydrophobic filter for cleanliness.2 A dirty filter can significantly reduce the amount of gas that is able to reach the sensor cell, thereby impairing the ability of the system to respond to a hazardous condition.2 Detronics also mentions, if the filter becomes dirty or if it is damaged, it must be replaced.2 PureAire does not use a filter; annual maintenance requires no filter replacement or visual check.

PureAire offers a unique, proprietary renewable sensor, which is a completely different technology than a disposable sensor cell.  Many of PureAire sensor cells can operate in 100% RH condensing environments with virtually zero drift.  Additionally our renewable sensor cell can operate outdoors in Texas summer heat or a North Dakota winter without the use of coolers and cell heaters.  Det-tronics H2S monitors operates their cells to, 15 to 90% RH, non-condensing environments.3
