Description
About the DS1923-F5# Hygrochron
The DS1923-F5# is a high-resolution iButton® focused on applications that require humidity logging and containing a complete temperature and humidity logging system. This is a reliable, flexible, low-cost data logger with excellent battery life. The DS1923-F5# is great in applications such as food preparation and processing, transportation of sensitive goods, warehouse monitoring, and environmental studies.
The temperature range of this device is -20°C to +85°C with an accuracy range of ±0.5°C in the range of -10°C to +65°C after software correction. The humidity range is 0% to 100% relative humidity. The DS1923-F5# has a programmable resolution of 0.5°C for the 8-bit and 0.0625°C for the 11-bit. The device can read 8192 values at a logging rate of 1 second to 273 hours for the 8-bit, and the 11-bit can read 4096 values with the same logging rate. Battery life information can be found on the DS1923-F5# data sheet.
The DS1923-F5# is calibrated against a NIST traceable source for temperature. A NIST traceable certificate for any DS1923-F5# purchased from iButtonLink is available for download on the Maxim website. A sample certificate can be seen here. Please see the iButton® Data-Logger Calibration and NIST Certificate FAQs for more information.
Calibration
This product comes with a Maxim Integrated certificate rated to 0.5 °C. If you are using our Hygrochrons for an application where you need a more accurate reading around a specific range of points, we suggest adding our 3-Point Accredited Temperature Calibration. Our 3-Point Accredited Temperature Calibration is for temperature only and does not give added data accuracy to the humidity readings of the Hygrochron.
When you choose our calibrated Hygrochrons, they will become part of a chain of traceability back to the National Institute of Standards and Technology. What does this mean for you?
- Calibrated to industry leading .02°C Uncertainty
- Proven accuracy
- Verified equipment quality
- Compliance with medical standards
NOTE: Maxim Integrated Circuits reliability studies have shown that the device survives a minimum of 1000 cycles of condensation and drying, but this product is not guaranteed for extended use in condensing environments.
Thermochron models vary in the operating temperature range, the amount of memory available for storage, and the accuracy of the temperature reading. Please check out the table below for comparisons with other models, as well as our Thermochron and Hygrochron page for more information.
