Massive, 5 cm-high display permits viewing from across the lab. Its microcomputer chip permits setting 3 countdown times into memory. Program the three most frequently used times and never set countdown times again. Use any countdown time from 99 minutes, 59 seconds to 1 second. When zero is reached, the timer starts counting up to show time elapsed since alarming.

这种报警器的大显示数字有5厘米高，在实验室的另一头就能看到。它配有微电脑芯片，可以在内存中设置3种倒计时间。只需将三种最常用的时间编入程序，以后就再不用设置倒计时间了。倒计时间范围是99分55秒到1秒。在达到零秒时，计时器便开式正数计时来显示从报警后开始的时间。

Unique green light fl ashes every second once the countdown time reaches 10 seconds. Red light fl ashes when zero has been reached and the alarm is sounding. Alarm has three switch positions which allow setting to a high decibel for noisy areas, low for quiet environments, or off (muted) for silent visual fl ashing LED operation.

在倒计时间达到10秒时，LED屏幕上每秒钟便会闪烁独特的绿色灯光。在达到零秒并响起警报后会闪烁红色灯光。警报声音有三个开关位置，在嘈杂地区可以将声音设置为高分贝，在安静环境中设置低分贝，还可以设置静音、仅使用闪烁的LED视觉操作。

To assure accuracy an individually serial-numbered Traceable? Certifi cate is provided from an ISO 17025 calibration laboratory accredited by A2LA (A2LA and CNAL calibration certifi cates are all mutually recognised). It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Magnetic back allows timer to be placed on any metal surface such as incubators or water baths. Also has a flip-open stand, a spring fastener for clipping to a notebook/clipboard, and an opening for a lanyard or hanging on a wall. Accuracy is 0.01%. Supplied with two AAA alkaline batteries. Size is 88.9 x 57.2 x 15.8 millimetres. Weight is 71 grams.

为了确保精度，每一只编有序列号的Traceable?产品都配有通过A2LA认证（A2LA与CNAL认证相互认可）的ISO 17025校准实验室授予的证书，它表示产品可以追溯到NIST（美国国家标准与技术研究院）制定的标准。这件计时器采用磁性背板，因而可以放置到任何金属表面上，比如放到孵化器或水浴槽上。它还配有一只翻开式座架、一只弹簧固定件，用来夹持在笔记本/书写板上，此外还有一只孔眼，以便用挂绳来悬挂到墙上。它的精度为0.01%，配有两节AAA碱性电池。计时器的尺寸为88.9 x 57.2 x 15.8毫米，重71克。

 

 

Allows simultaneous programming of two different activities from 99 hours, 59 minutes, 59 seconds to 1 second. Resolution is 1 second; accuracy is 0.01%. Each channel has a distinct electronic alarm and visual indicator when zero is reached. The alarm may be turned off or silenced automatically after 1 minute.

这种计时器可以分别针对两项活动而设置从99小时59分59秒到1秒钟的倒计时间。它的分辨率为1秒，精度0.01%。每个通道配有不同的电子警报和视觉指示，在达到零秒时便会发出警报和指示。警报可以关闭，或者在1分钟后自动停止。

For repetitive timing, the microcomputer chip permits setting 2 countdown times into memory. The memory recalls the last countdown time set. Large 1.6 cm high LCD digits may be read from 6 metres.

这款计时器采用微电脑芯片，对于重复计时可以将两种倒计时间设置到内存记忆中，它能恢复上一次的倒计时间设置。显示屏采用1.6厘米高的LCD大数字，六米开外就能看到。

Green light fl ashes for each channel every second the countdown time reaches 10 seconds. Red light fl ashes when zero has been reached and the alarm is sounding. Alarm has three switch positions which allow setting to a high decibel for noisy areas, low for quiet environments, or off (muted) for silent visual fl ashing LED operation.

到倒计时间达到10秒钟时，每个通道便会每秒钟闪烁绿灯。在达到零秒、警报响起后闪烁红色灯光。警报声音有三个开关位置，在嘈杂地区可以将声音设置为高分贝，在安静环境中设置低分贝，还可以设置静音、仅使用LED闪烁的视觉操作。
