New Cosmos Electric Co., Ltd. 個人暴露濃度計 XV-389 XV-389

Feature

• Measurement can be made in accordance with the "Guidelines for the Measurement of Personal Exposure to Chemical Substances" (established by the Japan Society for Occupational Health).
• Check exposure status at a glance with a trend graph (using the optional log data collection set).
• Target substances can be selected from among 17 chemical substances, including toluene. When the airborne concentration of the selected substance reaches the warning level (TWA, STEL), a buzzer or lamp notifies the user.
• Instantaneous, average, TWA (time weighted average), and STEL (short time exposure limit) values of airborne concentrations of chemical substances can be checked in real time.
• Compact and lightweight (H40 x W94 x D20 mm, approx. 62 g*), so it does not interfere with work.　Excluding protruding parts and the weight of the battery.
• *This product uses a highly sensitive gas sensor to measure and record the airborne concentration of chemical substances in gas form.
• Ideal for risk assessment of organic solvents and specified chemical substances.
