Detection Method / Sensor Type: Chemcassette colorimetric tape
Target Gas/Analyte: Diisocyanates — toluene diisocyanate (TDI), methylene bisphenyl isocyanate (MDI) and hexamethylene diisocyanate (HDI)
Measurement Range: TDI: 0.5 to 200 ppb. MDI: 0.5 to 200 ppb. HDI: 0.5 to 150 ppb
Relative Humidity Range: Optimum for best accuracy varies by gas — TDI 25-65%, MDI 5-80%, HDI 15-85% RH
Response Time: T50 at twice TLV — TDI 10 s, MDI 10 s, HDI 30 s
Resolution: Lowest alarm level 0.6 ppb for all three analytes
Additional Features: No sample line particulates filter required. TDI detection limit sits below the 2015 NIC TWA of 1 ppb
Sample Range / Line Length: Maximum sample line 0.15 m — the shortest of any Chemcassette, so the detector must be sited close to the monitored point
