This unique unit simultaneously displays time-of-day, temperature, and humidity. The clock displays AM/PM or 24-hour military time to the exact minute with 0.01% accuracy. Noting changes is easy with the triple display. Internal sensors make it ideal for use in hoods, storerooms, clean rooms, incubators, drying chambers, and environmental cabinets. At the touch of a button, the memory recalls the highest and lowest temperature and humidity readings. Permits monitoring conditions overnight, on weekends, or any time period. To assure accuracy, an individually serial-numbered Traceable® Certificate is provided. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).
I bought this one to replace my analog unit. It is the perfect size to hang on wall, or sit on shelf. But, worth mentioning-- In a previous review, a method to calibrate this unit was mentioned, so I contacted customer service to receive the same. I leave 4 stars instead of five because I received instructions for sending the unit back to the manufacturer for calibration---which, unfortunately would cost more than just buying another unit!
This is an excellent, portable thermometer. Being NIST tested it will be accepted by any inspector. Also long outdate (almost 2 years on each one I bought so far).
This is portable, well made and works great!
Very easy to use hygrometer and room temperature thermometer with clock. Only dislike is the re-calibration date lasts only 1-2 years.
likes. After expiration date, can we recalibrate or not? If recalibration is possible, can I receive the instruction, so I can do in lab. I appreciate.
I have found that this item is easy to read, and has a small footprint.
