Control Company’s Traceable memory card for humidity, temperature and dew point readings is a stand-alone unit with data logging capabilities.
The memory card stores readings from once a minute to once every 720 minutes on a removable standard SD memory card—identical to cards in digital cameras. The memory reader (supplied) plugs into any USB computer port with no software to install.
The text report includes date, time of day, sensor readings and may be sent to any spreadsheet or database. The unit monitors incubators, clean rooms, store rooms, labs, hoods and any critical areas. The unit records 5.9 million readings (over 10 years of minute-by-minute readings) and has 256 mb memory card (up to 4 gig card may be used).
Temperature range is 0 to 50.0°C with 0.1° resolution and ±1°C accuracy. Humidity range is 0.0 to 90.0 RH with 0.1 resolution; accuracy is ±5 percent RH at 25°C in range of 20 to 85 percent RH and ±7 percent RH elsewhere. Dew point range is -20.0 to 50.0°C with 0.1° resolution.
The minimum/maximum feature displays the highest/lowest readings for any time period. Alarm beeps and bright red LED flashes when temperature, humidity, and dew point rise above or fall below user-set trip points. Alarm can be set in 0.1 increments. A four-line display simultaneously shows ambient temperature, humidity, dew point and time of day. The unit operates using supplied batteries and/or supplied adaptor.
