Display & Backlight: Multifunction, multidigit monochrome dot-matrix display. Choice of white or red LED backlight.
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 & Graphical display Min/Max/Avg History: Logged history stored and displayed for every measured value. Manual and auto data storage. Min/Max/Avg history may be reset independently. Auto-store interval settable from 2 seconds to 12 hours*, overwrite on or off. Logs even when display off except for 2 and 5 second intervals. Kestrel 5 series units hold over 10,000 data points.
data Upload & Bluetooth Data Connect Option: Wireless range up to 100ft. Connection requires optional USB data transfer cable or Kestrel Link Dongle or Kestrel LiNK app. Employs Kestrel Link protocol for data transmission with Link supported devices. (Kestrel LiNK for iOS/Android, Kestrel Link for PC/MAC).
Clock/Calendar: Real-time hours:minutes:seconds clock, calendar, automatic leap-year adjustment.
Auto Shutdown: User-selectable – Off, 15-60 minutes with no key presses.
Languages: English, French, German, Spanish.
Battery Life: AA Lithium included. Up to 400 hours of use, reduced by backlight, alert light and buzzer, or Bluetooth radio transmission use.
Shock Resistance: MIL-STD-810g, Transit Shock, Method 516.6 Procedure IV; unit only; impact may damage replaceable impeller.
SealingWaterproof (IP67 and NEMA-6)
Display & Battery Operational Temperature Limits: 14° F to 131° F | -10 °C to 55 °C Measurements may be taken beyond the limits of the operational temperature range of the display and 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.
Size & Weight: 5.0 x 1.9 x 1.1 in | 12.7 x 4.5 x 2.8 cm, 4.3 oz | 121 g. (Lithium battery included)
