US Manufacturing

The entire Kestrel line is designed and built in the USA. No other handheld weather meter is. Some electronic components have to be sourced overseas these days, but Kestrel buys American wherever possible. Kestrel believes US manufacturing is the only way to ensure that every Kestrel will do its job right. Kestrel believes it’s important to do its part to keep manufacturing alive and well in the US.

SENSORS

SENSORS	ACCURACY (+/-)	RESOLUTION	SPECIFICATION RANGE	NOTES
AmbientTemperature	0.9 °F 0.5 °C	0.1 °F 0.1 °C	14 to 131°F -10 to 55 °C	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.
Pressure	1.5 hPa\|mbar 0.044 inHg 0.022 PSI	0.1 hPa\|mbar 0.01 inHg 0.01 PSI	25°C/77°F 700-1100 hPa\|mbar 20.67-32.48 inHg 10.15-15.95 PSI	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.
Storage Temperature	-22.0 °F to 140.0 °F \| -30.0 °C to 60.0 °C.

Description

Utilize the Kestrel DROP D3FW Fire Weather Monitor to monitor and record weather conditions and variations over a period of time, whether at a burn site or during a wildfire. Export data to access and analyze critical information for making informed decisions.

Kestrel DROP D3FW Fire Weather Monitor Overview

When managing a burn site, knowing environmental conditions are within prescription is important for compliance and to ensure a fire doesn’t get out of control. Gathering sufficient weather data from site visits to make a decision on when to burn can be challenging. In addition to the full wind and weather readings from a Kestrel weather meter, the new Kestrel DROP data loggers can be left on site recording a history of conditions and trends which can then be viewed on a mobile device when within range via Bluetooth and shared via email.

Small, Accurate, Rugged and Waterproof

Each Kestrel Fire Weather DROP measures just 1 x 1.8 x 2.4 inches (24 x 46 mm x 60 mm) and weighs just 1.2 ounces (34 grams). DROP loggers meet military and international standards for water, dust and shock resistance (IP-67 and MIL-STD-810G) and are conveniently equipped with a sturdy D-ring for hanging wherever needed.

Log, View and Share on the Kestrel LiNK App

Kestrel LiNK is the free app that powers the Fire Weather DROP data logger. With Kestrel LiNK on your smart phone or tablet, you can view real-time readings from any DROP logger within wireless range (up to 100’ or more line of sight) via Bluetooth® low energy. Min/Max/Average readings are clearly displayed and the data log is viewable as a scrolling graph with detailed data for each logged point. The Kestrel LiNK 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. You can also send and share real-time and logged environmental data via email, Facebook or Twitter.

Battery Life:

The battery life will vary based on usage.
For baseline conditions and settings*, the battery will last approximately 6 months. *Temp = 75°F, Logging Rate = 10 Minutes, Update Rate = 30 seconds.
Battery life will be reduced by colder conditions and more frequent logging or update rates
Downloads of large data logs (or firmware updates) are best completed with a fresh battery and in temperatures above 10°C / 50°F.

Requirements:

iOS 6 installed iPhone 4s, iPad 3rd generation, iPod Touch 5th generation and above.
Android 4.2 and higher. Works with most Android devices with Bluetooth® low energy, including Samsung Galaxy, Nexus 4, Motorola Droid, and other recent generation phones and tablets.
