Application Range:
| Standard Measuring Range: | 0.2 to 6 ppm |
| Number of Strokes n: | 1 |
| Time for Measurement: | approx. 55 s |
| Standard Deviation: | ± 15 to 20 % |
| Colour Change: | yellow to pink |
Ambient Operating Conditions:
| Temperature: | 15 to 40 °C |

Reaction Principle:
H2S + HgCl2 ~> HgS + 2 HCl HCL + pH indicator ~> pink reaction product
Cross Sensitivity:
Up to 1000 ppm, sulfur dioxide has no influence on the reading. Within the range of their TLV, mercaptanes, arsine, phosphine and nitrogen dioxide are also indicated, however, with differing sensitivity. Within its TLV, hydrogen cyanide changes the color of the tire indicating layer to a light orange. The reading of hydrogen sulfide is not affected..
