Cole-Parmer 5095CP 可追踪倒计时控制器

Cole-Parmer 5095CP 可追踪倒计时控制器

不受频率变化，确保高精确度和可重复性！

石英晶体时基提供的精度为±0.015％，在10秒，在10秒±0.005％的可重复性。

五位LED亮度可调，既会显示剩余时间计数下降到零或经过的时间（从零）。

控制器适合可重复的，持续进行的计划！

每个型号有四个不同的声音报警序列：（1）节拍器每秒的蜂鸣声;（2）第二，周期结束音;（3）每30秒发出蜂鸣节拍器在最后的10秒，和周期结束音或（4）无音。设置或两个500瓦交流电源插座，一个周期内开启或关闭。两个逻辑电平输出插孔提供一个逻辑电平兼容的信号并行与相应的交流电源插座。

薄膜键盘防尘，容易清洁。可选接触器（用于高电流），和脚踏开关（用于遥控器）下面分别设置周期从0.1秒到59分钟59.9秒通过一个按钮，每个数字对应的。周期结束时定时器自动复位，只需按下START / HOLD键重复一个给定的周期。非常适于快速生产工作或重复实验。控制器可用于定时关机，或任何启动测试。手动操作设备开启或关闭不扰乱程序。控制器还可编程14种不同的关闭/开启每日时钟开关切换，高达196每周开启/关闭开关切换。液晶显示器是1/2“高，0.01％的准确度。倒计时的控制器是可编任何一分钟的时间间隔23小时，59分钟，59秒到1分钟。每个控制器提供一个唯一的序列编号NIST可追踪®证书。

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.
