The AutoStep Plus is a microprocessor-controlled instrument for leak detection, survey work, area monitoring and emergency response involving isocyanates. The AutoStep produces a color reaction on a paper tape cassette that is gas specific. The alpha-numeric LCD display shows concentration and an 80 dB alarm alerts the user to a preset level of isocyanate exposure. Software is included with the rental unit. The paper tape cassette, which is a purchased item, supplies 16 hours of continuous monitoring. A single tape is used for TDI, MDI or HDI, with the user selecting the gas type. The tape does not have to be refrigerated.
