Traceable® humidity/temperature/dew point meter traceable unit displays humidity to 0.01%, use for QC, ISO 9000, and R/D: Traceable® digital hygrometer/thermometer/dew point instrument, by using a special breed of artificial intelligence, provides a response time of under 10 seconds. It samples one-and-a-half times per second. Fuzzy logic algorithm pinpoints the exact answer almost instantly. Fast response with high accuracy: Direct-reading instrument. Certified Traceable to NIST, to assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Clean room and food applications, fulfills federal CLIA requirements and is ideal for hoods, clean rooms, food storage, process control, incubators, desiccators, drug manufacturing, environmental chambers, corrosion analysis, and inside/outside air monitoring. Four-digit LCD can be read from 10-foot Rugged handheld unit is designed for years of service. Hi/lo memories, programmable alarms, and data output. Memory recalls both minimum and maximum readings in dew point, temperature, and humidity at any time. High and low alarms can be programmed in dew point, temperature, and humidity. When an out-of-range condition is sensed, an alarm sounds and the display flashes. Computer output permits data to be captured, transferred, stored, and printed. Supplied with 9-volt battery for 1-year intermittent usage or 100 continuous hours. AC adaptor (not supplied) is available. Complete with Traceable® Certificate and ABS hard plastic carrying case. Replacement battery Cat. No. 1112.
