Why choose thelockerguy wholesale?

It is critical to measure relative humidity, wind speed and wind direction in order to minimise waste and maximize safety when crop spraying. In hot, dry conditions, expensive chemicals may evaporate into the air rather than onto your crops. Delta T allows you to accurately assess acceptable spraying conditions to ensure you’re within guidelines and help you select the right spray nozzle. The Kestrel 3500 DT is the difference between wet bulb and dry bulb temperatures and is an accurate predictor of chemical evaporation rates. The Kestrel 3500 Delta T incorporates barometric pressure correction in its wet bulb temperature calculation, ensuring accuracy even on low pressure days, at high altitudes, and in very dry weather. No other pocket weather meter offers this feature with this level of accuracy.

Specification

Primary Measurement	Units	Resolution	Accuracy (+/-)	Range: Max Operational Specification (if less)	Notes
Wind Speed or Air Velocity	m/s	0.1	Larger of 3% of reading, least significant digit or 20 ft/min	0.6 to 60.0 m/s 0.6 to 40.0 m/s	1 inch diameter impeller with precision axle and low-friction Zytel® bearings. Start-up speed stated as lower limit, readings may be taken down to 0.4 m/s \| 79 ft/min \| 1.5 km/h \| .9 mph \| .8 kt after impeller start-up. Off-axis accuracy -1% @ 5° off-axis; -2% @ 10° -3% @ 15°. Calibration drift < 1% after 100 hours use at 16 MPH \| 7 m/s. Replacement impeller (NK PN-0801) field installs without tools (US Patent 5,783,753).

	Beaufort	1		0 to 12 B
Temperature	°F	0.1	1.8 °F	-49.0 to 257.0 -20.0 to 158.0	Air, water or snow temperature. Hermetically-sealed, precision thermistor mounted externally and thermally isolated (US Patent 5,939,645) for rapid response. Airflow of 2.2 mph \| 1 m/s or greater provides fastest response and reduction of insulation effect. Calibration drift negligible.
Temperature	°C	0.1	1.0 °C	-45.0 to 125.0 -29.0 to 70.0
Relative Humidity	%RH	0.1	3.0 %RH	0.0 to 100.0% 5.0 to 95.0% non-condensing	Polymer capacitive humidity sensor mounted in thin-walled chamber external to case for rapid, accurate response (US Patent 6,257,074). 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 +/- 2% over 24 months. RH may be recalibrated at factory or in field using Kestrel Humidity Calibration Kit (NK PN-0802).
Pressure	inHg	0.01	typical 0.04 inHg max 0.07 inHg	0.30 to 32.48 inHg	Air pressure at the location. Adjustable reference altitude allows display of station pressure or barometric pressure corrected to MSL. Monolithic silicon piezoresistive pressure sensor with second-order temperature correction. Pressure sensor may be recalibrated at factory or in field. Kestrel 2500 and 3500 display continuously updating three-hour barometric pressure trend indicator: rising rapidly, rising, steady, falling, falling rapidly. Kestrel 4000 series displays pressure trend through graphing function.
Pressure	hPa (mb)	0.1	typical 1.5 hPa max 2.5 hPa	300.0 to 1100.0 hPa 10.0 to 1100.0 hPa
Wet Bulb Temperature (Psychrometric)	°F	0.1	3.6 °F	Refer to stated ranges for temp., relative humidity and pressure.	Temperature indicated by a wet bulb psychrometer under forced aspiration. Calculated from temperature, relative humidity and pressure.
Wet Bulb Temperature (Psychrometric)	°C	0.1	2.0 °C
Dewpoint	°F	0.1	3.6 °F	Refer to stated ranges for temp. and relative humidity.	Temperature to which the air must be cooled at a constant pressure for water vapour to condense into water. Calculated from temperature and relative humidity.
Dewpoint	°C	0.1	2.0 °C	Refer to stated ranges for temp. and relative humidity.
Delta T	°F	0.1	5.4 °F	Refer to stated ranges for temp., relative humidity and pressure.	Difference between dry bulb temperature and wet bulb temperature. When spraying, indicates evaporation rate and droplet lifetime. Safe range for pesticide spraying is 4 to 16 °F / 2 to 9 °C.
Delta T	°C	0.1	3.0 °C
Altitude	ft	1	typical 50 ft max 98 ft	-2,300 to 85,000 ft	Height above Mean Sea Level (“MSL”). Temperature compensated pressure (barometric) altimeter requires accurate reference barometric pressure to produce maximum absolute accuracy.
Altitude	m	1	typical 15 m max 30 m	-700 to 25,900 m
Max/Avg Wind	One-button clear and restart of Max Wind Gust and Average Wind measurement by powering down and restarting unit.
Display & Backlight	Reflective 5 digit LCD. Digit height 0.36 in / 9 mm. Choice of aviation green or visible red (NV models only) electroluminescent backlight. Manual activation with auto-off.
Response Time & Display Update	All measurements except those based on relative humidity respond accurately within 1 second. Relative humidity and all measurements which include RH in their calculation may require as long as 1 minute to fully equilibrate to a large change in the measurement environment. Display updates every 1 second.
Clock / Calendar	Real-time hours:minutes clock.
Operational & Storage Temperature Range	The operational temperature range of the liquid crystal display and batteries is 14° F to 131° F / -10 °C to 55 °C. Measurements beyond the operational range can be taken by briefly exposing unit to extreme conditions such that the display and batteries remain within the operational range. Storage range -22 °F to 140 °F / -30 °C to 60 °C.
Auto Shutdown	After 45 minutes of no key presses.
Certifications	CE certified, RoHS and WEEE compliant. Individually tested to NIST-traceable standards (written certificate of tests available at additional charge).
Battery	CR2032, one, included. Average life, 300 hours. Battery life reduced by backlight use in 2000 to 3500 models.
