The Daigger High Accuracy Hand-Held Thermohygrometers has a 4 digit LCD display that is viewable up to 10 feet away. It is ideal for hoods, clean rooms, food storage, process control, incubators, desiccators, drug manufacturing, environmental chambers, corrosion analysis, and internal/external air monitoring. It samples at a rate of once per second and uses fuzzy logic algorithm to pinpoint the answer quickly. Traceable unit displays humidity values to 0.01% and is acceptable for use in QC, ISO 9000, and research and development laboratories.
Each unit features additional functionality such as Hi/Lo memory capability, programmable alarms, and data output. The memory feature is able to recall both minimum and maximum readings in dew point/frost point, temperature, and humidity readings. Both high and low alarms can be set for each variable. In the event of an out-of-range condition, the alarm will sound along with a flashing display. The unit is equipped with computer output capabilities that allow data to be captured, transferred, stored, and printed for quality purposes.
Each unit is supplied with a serial-numbered Traceable® certificate provided from the ISO17025 calibration laboratory accredited by A2LA. Traceability standards are in accordance with NIST (National Institute of Standards and Technology). Each unit is also supplied with a 9-volt battery good for 1 year of use or 500 continuous hours and a durable ABS hard plastic carrying case. An AC adapter is available but is sold separately.
