Traceable® Digital Barometer, Each

Details:

Specifications digital barometer is the perfect unit for plants, labs, and all other environments where there is a need to monitor conditions of environmental air parameters. Traceable® digital barometers have a four-line lcd that continuously and simultaneously shows barometric pressure, temperature, relative humidity, barometric pressure trend and time-of-day. Traceable® digital barometers have minimummaximum readings for barometric pressure, temperature and relative humidity are stored every hour for the last 24 hours and are available for recall at the touch of a button.Measuring ranges barometric pressure range from 500 to 1030 millibars (mbar) with a resolution of 1 mbar. Accuracy is ±4 mbar. Barometric pressure trend shows in bar-chart format the current and past 1-, 3-, 6-, 12-, and 24-hour readings. Switching permits viewing in millibars (mbar), inches of mercury (inhg), or hectopascals (hpa). Altitude compensation is –100 to 2500 meters.Temperature range is 32 to 131ºf and 0 to 55ºc. Resolution is 0.1° And accuracy is ±0.4°C. Relative humidity range is 0 to 95%. Resolution is 1% rh and accuracy is ±3% rh between 5 to 75%, otherwise ±5% rh.Computer output allows unit to be connected to a computer using the accessory computer data acquisition system to permanently capture readings.Traceable to nist for accuracy an individually-numbered traceable® certificate is provided which assures accuracy from our iso/iec 17025:2005 calibration laboratory accredited by a2la. It indicates traceability to standards provided by nist (national institute of standards and technology). Supplied: traceable® certificate, wall mount, flip open stand and batteries. Size: 4 x 3 x 1 inches. Weight: 7 ounces.Please note: the aforementioned a2la accreditation belongs to the manufacturer, not thomas scientific.Cole-parmer item number6800049max humidity rh (inside) (%)95max temperature (inside) (° c)55max temperature (inside) (° f)131max barometric pressure (psi)14.94Humidity accuracy (inside)±3% (5 to 75%), otherwise ±5%height (in)3height (cm)7.6Depth (in)1depth (cm)2.5Data loggingstream live data to pc with 68000-51 data acquisition softwarebattery typethree aaa (included)barometric pressure resolution (psi)0.1 Hg (1 mbar)barometric pressure accuracy (psi)±0.12 " Hg (4 mbar)temperature resolution (inside) (° f)0.1
