Cole-Parmer 5095CP 可追蹤倒計時控制器

Cole-Parmer 5095CP 可追蹤倒計時控制器

不受頻率變化，確保高精確度和可重復性！

石英晶體時基提供的精度為±0.015％，在10秒，在10秒±0.005％的可重復性。

五位LED亮度可調(diào)，既會顯示剩余時間計數(shù)下降到零或經(jīng)過的時間（從零）。

控制器適合可重復的，持續(xù)進行的計劃！

每個型號有四個不同的聲音報警序列：（1）節(jié)拍器每秒的蜂鳴聲;（2）第二，周期結(jié)束音;（3）每30秒發(fā)出蜂鳴節(jié)拍器在最后的10秒，和周期結(jié)束音或（4）無音。設置或兩個500瓦交流電源插座，一個周期內(nèi)開啟或關閉。兩個邏輯電平輸出插孔提供一個邏輯電平兼容的信號并行與相應的交流電源插座。

薄膜鍵盤防塵，容易清潔。可選接觸器（用于高電流），和腳踏開關（用于遙控器）下面分別設置周期從0.1秒到59分鐘59.9秒通過一個按鈕，每個數(shù)字對應的。周期結(jié)束時定時器自動復位，只需按下START / HOLD鍵重復一個給定的周期。非常適于快速生產(chǎn)工作或重復實驗。控制器可用于定時關機，或任何啟動測試。手動操作設備開啟或關閉不擾亂程序。控制器還可編程14種不同的關閉/開啟每日時鐘開關切換，高達196每周開啟/關閉開關切換。液晶顯示器是1/2“高，0.01％的準確度。倒計時的控制器是可編任何一分鐘的時間間隔23小時，59分鐘，59秒到1分鐘。每個控制器提供一個唯一的序列編號NIST可追蹤?證書。

Unaffected by frequency variations—ensuring high accuracy and repeatability!

Quartz crystal time base provides an accuracy of ±0.015% at ten seconds with a repeatability of ±0.005% at ten seconds.

Five-digit LED has adjustable brightness and will display either remaining time count (down to zero) or elapsed time (up from zero).

Controller is ideal for repeatable, on-going programs!

Each model has four different audible alarm sequences: (1) a metronome beep each second; (2) a one-second, end-of-cycle tone; (3) a beep every thirty seconds with a metronome for the last ten seconds, and an end-of-cycle tone; or (4) no tone at all. Set either or both 500 W AC outlets to be on or off during a cycle. Two logic-level output jacks provide a logic-level compatible signal parallel with corresponding AC outlets. 

The membrane keypad resists dust and allows easy cleaning. Optional contactor (for use with high currents), and foot switch (for remote control) are available separately below. 

Set cycles from 0.1 second to 59 minutes, 59.9 seconds via a push button corresponding to each digit. Timer automatically resets at end of cycle; just press START/HOLD button to repeat a given cycle. Ideal for quick production work or repetitive experiments. Controller can be used for timed shutdown or start up of any test. Manual override permits equipment to be switched on or off without disturbing the program. Controller also allows programming for 14 different off/on daily clock switchings, up to 196 on/off switchings per week. LCD display is 1/2" high and has accuracy of 0.01%. Countdown controller is programmalbe in any one-minute intervals from 23 hours, 59 minutes, 59 seconds to 1 minute. Each contoller is provided with an individual serial numbered NIST Traceable? certificate.
