Product Description

Kestrel 3500DT Delta-T Pocket Weather Meter – USA-Made, Essential Weather Data for Optimal Spraying Conditions – Waterproof, Floats, Includes 5-Year Warranty

The Kestrel 3500DT Delta-T Pocket Weather Meter is a professional-grade tool designed to provide accurate and comprehensive weather data, crucial for agricultural applications like crop spraying. Built in the USA, this reliable weather meter measures key environmental factors including wind speed, temperature, barometric pressure, relative humidity, dew point, and Delta-T—a critical value for assessing optimal spraying conditions. Whether you're a farmer, pest control professional, or field expert, the Kestrel 3500DT ensures you're always working within safe, effective conditions and helps you select the right spray nozzle for the job.

    Why the Kestrel 3500DT is Perfect for Spraying Applications:

    The Kestrel 3500DT Delta-T Pocket Weather Meter is specifically designed to help you assess optimal spraying conditions by measuring Delta-T and other critical environmental factors. By understanding Delta-T, you can ensure your spraying activities are within acceptable guidelines and choose the correct spray nozzle for optimal application, improving efficiency and reducing waste. Whether you're working in agriculture, pest control, or any outdoor setting, this meter provides all the data you need to make informed decisions for safer, more effective spraying.

    Product Features

    Delta-T for Optimal Spraying Conditions: The Delta-T measurement is essential for determining the best environmental conditions for spraying. By assessing Delta-T, you can accurately evaluate whether conditions are within safe guidelines for effective pesticide, herbicide, or fungicide applications. It also helps you select the right spray nozzle, ensuring that your application is both effective and efficient.

    Comprehensive Weather Data: In addition to Delta-T, the Kestrel 3500DT measures wind speed, temperature, barometric pressure, relative humidity, dew point, altitude (barometric), wet bulb temperature, and pressure trend, giving you all the data you need to make informed decisions during outdoor and agricultural operations.

    USA-Made Quality: The Kestrel 3500DT is designed and built in the USA, offering precision engineering and high-quality materials to ensure long-lasting, reliable performance.

    Waterproof & Floats: Fully waterproof and built to float, the Kestrel 3500DT is perfect for outdoor and water-based activities. Whether you're working in wet conditions or near water, you can rely on this durable device to deliver accurate readings.

    Easy-to-Use Operation: With its simple three-button operation, the Kestrel 3500DT is user-friendly, allowing you to quickly access all of its weather measurement features with ease.

    5-Year Manufacturer's Warranty:The Kestrel 3500DT comes with a 5-year manufacturer’s warranty, ensuring that you get a reliable, long-lasting instrument backed by the manufacturer’s commitment to quality.

    Compact & Portable: This lightweight and portable device fits easily in your pocket, making it ideal for professionals who need weather data on the go.

    Certificate of Conformity: Each Kestrel 3500 includes a certificate of conformity, confirming that it meets high standards of quality and provides precise, accurate measurements.

    Data Hold Mode: The Hold Mode is helpful for capturing measurements when you're unable to view the display in real-time.

    High-contrast monochrome LCD display: Easily readable in direct sunlight.

    User-Replaceable Impeller: Every Kestrel Impeller is tested at high and low speeds. The impeller is easily replaced if needed.

    Slip-On Protective Cover: Keep your Kestrel protected when not in use with a hard cover that simply slides up the lanyard and over the Kestrel.

    • Urgent need for my K2 winter expedition.

      I needed urgent for my K2 winter expedition. I was on the last min and needed the goods to be sent in Iceland. Their chat online worked 100% and I was able to add on one extra peace even after I checkout. They send with UPS same day and I had the package 3 days later here in Iceland. Extreme Meters works and has good service I recommend them.

    • The service was prompt and cordial.

      The service was prompt and cordial. The Kestrel is used to measure wind velocity and temperature when applying pesticides for agriculture crop production. It is also used to measure weather conditions for livestock comfort.
