Datasheet ZMOD4410 (Renesas) - 10

link to page 10 link to page 9 link to page 10 ZMOD4410 Datasheet The ZMOD4410 can respond reliably to al of the types of organic compounds that are typically found in indoor environments. To assess the response of the gas sensor module to the levels described in the UBA study, the module has been tested using several TO-15/17 multi- component TVOC standards defined by the EPA. The ZMOD4410 response to the EPA standard with the TVOC levels from UBA is shown in Figure 3. A third-party report and certification from an independent research lab is available on the Renesas website that confirms the good conformity for IAQ measurements with respect to the UBA study and EPA standard.
Table 6. Level of Air Quality Based on TVOC Levels Described by UBA Renesas IAQ Rating Reference Level* Air Information TVOC (mg/m3) [a] Air Quality
≤ 1.99 Level 1 Clean Hygienic Air (target value) < 0.3 Very Good 2.00 to 2.99 Level 2 Good Air Quality (if no threshold value is exceeded) 0.3 to 1.0 Good 3.00 to 3.99 Level 3 Noticeable Comfort Concerns (not recommended for exposure > 12 months) 1.0 to 3.0 Medium 4.00 to 4.99 Level 4 Significant Comfort Issues (not recommended for exposure > 1 month) 3.0 to 10.0 Poor ≥ 5.00 Level 5 Unacceptable Conditions (not recommended) > 10.0 Bad [a] Conversion from mg/m3 to ppm for most common TVOC is by the factor approximately 0.5; for example, 10mg/m3 equals approximately 5ppm. Conversion from ppm to ppb is by the factor 1000; for example, 0.1ppm equals 100ppb.
