The ACR-205 data logger has channels for temperature, relative humidity, and carbon dioxide, as well as two channels that can be used for any of 10 interchangeable sensors for detecting toxic or dangerous gases (CO, oxygen, chlorine, NH3, H2, HCL, H2S, NO, NO2, and SO2). Sensors can be switched when the data logger’s power is off; readings from a newly installed sensor are available as soon as power is restored. Other features include 12-bit resolution accuracy, real-time display of all channels, customizable alarm points, and a choice of either an AC adapter or an eight-hour rechargeable lead acid battery.
