Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. For greatest accuracy, avoid direct sunlight on the temperature sensor and prolonged sunlight exposure to the unit in low airflow conditions. Calibration drift is negligible for the life of the product. For further details, see Battery Operational Temperature Limits.
Relative Humidity 2%RH 0.1 %RH 10 to 90% 25°C noncondensing To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift is typically less than ±0.25% per year.

Monolithic silicon piezo-resistive pressure sensor with second-order temperature correction. Between 1100–1600 mbar, unit will operate with reduced accuracy. Sensor may not operate above 1600 mbar and can be damaged above 6,000 mbar or below 10 mbar. Calibration drift is negligible for the life of the product.

ADDITIONAL PRODUCT INFO
Response Time & Display Update Display updates every 1 second. After exposure to large environmental changes, all sensors require an equilibration period to reach stated accuracy. Measurements employing RH may require longer periods particularly after prolonged exposure to very high or very low humidity. WBGT requires about 8 minutes to reach 95% accuracy and about 15 minutes to reach 99% accuracy after exposure to large environmental changes.
Data Storage Logged history stored for every measured value. Auto-store interval settable from 2 seconds to 12 hours*, overwrite on or off. D1: >13,000 data points, D2: >7,000 data points, D3: >6,000 data points.
Bluetooth® Data Connect Option Wireless range up to 100ft|30m. Compatible with Kestrel LiNK app for iOS (model 4s and later) and select Android products (Android 4.3 and higher) (See website for complete list of compatible 3rd party apps).
Certifications CE certified, RoHS, FCC, IC tested and WEEE compliant. Individually tested to NIST-traceable standards.
Origin Designed and manufactured in the USA from US and imported components. Complies with Regional Value Content and Tariff Code Transformation requirements for NAFTA Preference Criterion B.
Battery User-replaceable CR2032 (included).
Shock Resistance MIL-STD-810g, Transit Shock, Method 516.6 Procedure IV; unit only; impact may damage replaceable impeller.
Sealing Waterproof (IP67 and NEMA-6)
Battery Operational Temperature Limits 0° F to 140 ° F | -18 °C to 60°C Measurements may be taken beyond the limits of the operational temperature range of batteries by maintaining the unit within the operational range and then exposing it to the more extreme environment for the minimum time necessary to take reading.

Description

The Kestrel DROP is a highly durable environmental data logger that is incredibly easy to employ.

Monitor and record the conditions of any environment and easily access and chart real-time and historical data on your phone or tablet. A Kestrel DROP D2 logger can be placed wherever needed to log temperature and humidity with the data logs retrieved wirelessly and automatically to the Kestrel Connect app when within range(up to 100ft.). Kestrel DROP data loggers are designed to be used anywhere you need to track environmental conditions. DROP loggers meet military and international standards for water, dust and shock resistance (IP-67-30 minute submersion at 1m and MIL-STD-810G drop tested) and are equipped with a sturdy D-ring for hanging wherever needed.

    All you need is a DROP and a Smartphone with the free Kestrel LiNK app!

    Kestrel LiNK is the free app that powers the DROP loggers. With Kestrel Connect, you can view real-time readings from any DROP logger within wireless range (100’ or more line of sight) via Bluetooth® low energy Each phone or tablet can connect to up to 8 DROP loggers at the same time and store data logs from many more. Min/Max/Average readings are clearly displayed and the log is viewable as a scrolling graph with detailed data for each logged point. The app also allows adjustment of the logging interval and other settings as well as real-time threshold alerts. Readings can be updated as frequently as every 2 seconds and logging time and date are automatically updated whenever connected to your smart device. Send and share real-time and logged environmental data via email, Facebook or Twitter.

    I love this sensor and have bought three of them and have given two away to my church. Sorry to say they are not engineers and may not, as of yet, realize their value. These sensors are bluetooth, but can store 20 days of data when in range, can be downloaded very easily to e-mail and printed out ( temp, RH
    HI, DP)) after you set the interval from the APP. Flu season is just around the corner and you know ( I hope you do) that getting it right can save lives. You can bet it all that if they don't, they want see my smiling face at church!!!
