The IsoSense is a portable and economical sampling device ideal for measuring vapor and aerosol levels of isocyanate compounds including MDI and TDI down to 1 ppb. It is specially designed for personal exposure evaluations, area surveys and emergency response.
Simple samples are taken by first placing a pretreated test strip in a specially designed test strip holder. Next, start the state of the art pump which is preset for analysis time and flow. Once the sampling is complete, remove the test strip and compare the color change with the calibrated comparator color wheel to determine the exposure concentration.
The IsoSense sampling unit has a digital display which displays battery life, flow rate and sample time. This smart sampling unit is constantly checking for restricted air flow, blocked air flow or over flow while automatically adjusting and maintaining the preset value.

Please Note: Because of the ease of use, the reliability and the direct reading capabilities of the IsoSense Sampling Kit for MDI, it is often asked if this instrument can be used to measure the airborne levels of polymeric MDI (PMDI). It is recommended that the MDI IsoSense should only be used as a rough indication of the PMDI airborne concentration. The monitor should not be used when it is necessary to accurately quantitate the airbone concentration of PMDI. PMDI's are mixtures that vary in composition between manufacturers and product grades. In order to have an accurate concentration calibration of a monitor for a PMDI, the monitor would have to be calibrated on the specific material and grade that is used in the intended workplace.
