E Instruments, Langhorne, Pa, has released a zero filter attachment that enables more accurate zeroing of the company’s gas sensors for volatile organic compounds (VOC). The filter removes VOCs and other toxic gases (except CO2) from the ambient air, and allows the instrument to measure the zero point for the VOC gas sensor. Once the filter is removed, the instrument can obtain a more accurate VOC reading. For more information, visit E Instruments.
