A.3. Toxic (E-Chem) Sensor Specifications
The Company offers two (2) types of E-Chem Sensors: Standard and Rock Solid.
• Standard E-Chem Sensors – Capable of detecting higher concentrations than the Rock Solid E-Chem Sen
-
sors.
• Rock Solid E-Chem Sensors – Baseline is more stable and accurate. Allows lower range and lower alarm set
-
tings. Less susceptible to interference gases. Faster response and recovery time then Standard E-Chem Sen
-
sors.
