Normal breath readings will be between 80-150 ppb. Readings of the dental staff are often lower because of superior oral hygiene.
Research reports about the etiologies of breath malodor agree that the vast majority of halitosis originates with the anaerobic bacterial degradation of sulfur containing amino acids within the oral cavity, resulting in the emission of hydrogen sulfide (H2S), methyl mercaptan (CH3SH), and dimethyl sulfide (CH3SCH3), collectively referred to as volatile sulfur compounds (VSC). The Halimeter®…
My Halimeter® is displaying a normal reading or even a very low reading, even though the patient has noticeable halitosis.
Remember that the Halimeter® responds to sulfur compounds. Although most oral malodor is sulfur-based, it is possible that the odor you smell is not being caused by sulfur compounds. A very low reading, and/or sluggish instrument response, indicates that the sensor is nearly dead. It will then be necessary to replace the sensor.
If the sensor is more than a couple years old, it is possible to experience erroneous readings. You might obtain a low reading and high reading on the same patient during the same session. This is due to the sensor decaying and thus being in need of replacement.
Under normal use, the sensor will last 2-3 years. An indication that the sensor needs to be replaced is a slow and sluggish response to breath readings, or no readings at all.
Our experience has shown that the sensor usually needs to be replaced before re-calibration is necessary. Contact our service department for current pricing on re-calibration and sensor replacement. If the sensor is more than a couple of years old, we suggest replacing it, as even if it is re-calibrated, there is no reliable way to…
Normally, we can repair or recalibrate the instrument within one week of receiving it.

My Halimeter® readings are jumping all over the place and the sensor is new; or I am witnessing the readings jumping ±100-200 ppb.
All new sensors are a little more sensitive than the sensor you replaced. Remember that the instrument is reading in ppb (parts-per-billion) levels. As time goes by, a new sensor will calm down a bit. It is normal for the Halimeter®readings to jump ±10 ppb. If you are observing the instrument spiking quickly either positive…
As the instrument gets older, there can be an accumulation of particles of dust or dirt, that have been drawn into the Halimeter®. These particles can prevent the ball from moving. If you tap the top of the flowmeter with an object, this should release the ball.
