COLE-PARMER EW-94400-72 时间控制器
Cole-Parmer Digital Countdown Controller with NIST-Cal Cert; 115 VAC
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.
