Kestrel 2500手持式氣象儀

Kestrel 2500手持式氣象儀具有Kestrel 2000的所有功能，并增加了大氣壓和海拔高度的測(cè)量。一個(gè)趨勢(shì)箭頭可以顯示大氣壓值是增加、降低或者保持平穩(wěn)狀態(tài)，當(dāng)NK2500關(guān)機(jī)的情況下，大氣壓的監(jiān)測(cè)依然在進(jìn)行。 Kestrel 2500可以以數(shù)字形式直接顯示當(dāng)前海拔高度值，適用于爬山、登高等等戶外活動(dòng)。Kestrel 2500是旋轉(zhuǎn)風(fēng)杯式風(fēng)速儀，體積小巧，方便攜帶。采用高精度軸承，輕量葉輪，可測(cè)量風(fēng)速值，即便是在風(fēng)速很小的情況下。如果葉輪損壞，可更換。內(nèi)置溫度和大氣壓傳感器。

Kestrel 2500采用低功耗微處理器，明亮LCD顯示，可讀取當(dāng)前風(fēng)速、更大風(fēng)速、平均風(fēng)速并能選擇風(fēng)速單位。對(duì)于夜晚黑暗使用環(huán)境，NK2500草綠色版本還特別增加設(shè)計(jì)了紅色背景光，可提供照明。采用標(biāo)準(zhǔn)鋰電池，可更換，能保證操作至少300小時(shí)。如果風(fēng)速儀在過45分鐘都沒有任何操作的話，將會(huì)自動(dòng)切斷電源。便攜式包裝，防水、防震設(shè)計(jì)，能飄浮在水上。

NK2500風(fēng)速儀可以測(cè)量風(fēng)速、氣壓、氣壓變化趨勢(shì)、溫度等多項(xiàng)氣象參數(shù)，手持式便捷外觀，操作非常便捷，使用三個(gè)按鍵即可完成所有的測(cè)量操作。待機(jī)45分鐘后自動(dòng)關(guān)機(jī)，優(yōu)良的防水性能，適合實(shí)驗(yàn)室或野外現(xiàn)場(chǎng)測(cè)量。背景燈顯示功能和實(shí)時(shí)時(shí)鐘，數(shù)據(jù)鎖定功能，為野外氣象監(jiān)測(cè)帶來方便。風(fēng)速測(cè)量分為更大風(fēng)速，實(shí)時(shí)風(fēng)速，平均風(fēng)速，提供全面可靠的數(shù)據(jù)。

Kestrel Meter 2500 Weather Meter

The Kestrel 2500 Pocket Weather Meter measures wind and temperature with total accuracy, and has the added benefits of an air pressure sensor that provides altitude and barometric information. Kestrel 2500 technology enables you to follow changes in air pressure that help predict impending changes in the weather. Factor in the 2500's digital altimeter, and you have most of the weather information you need for outdoor activities ranging from model airne flight to rifle practice.

A quick compare chart of the basic models shows you the quick differences. 

As with all our Kestrels, the 2500's sensitive and user-receable impeller technology provides accurate wind speed info. Additionally, an external temperature sensor and waterproof casing allow you to gauge the temperature of water (it even floats) and snow, as well as the open air. A hard slide-on case, lanyard, and battery are included.

The Kestrel 2500 was originated as a basic model for long range shooters at an affordable price and someone who didn't need the ballistic features build in like the 5700 Elite.  A simple video shows how to achieve station pressure with a Kestrel 2500. 

For those using it at night, the Olive Drab NV version of the Kestrel 2500 features a night-vision preserving backlight. Backlight incorporates optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision.  (Note: This backlight appears soft greyish pink, not "red", and is still in the visible spectrum, so is not compatible with night-vision equipment.)
