Traceable Flashing LED Alert Big-Digit Alarm Timer

Traceable 閃爍LED顯示大數(shù)字報警計時器
 

Easy on the eyes輕松顯眼
 

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.

這種報警器的大顯示數(shù)字有5厘米高，在實(shí)驗(yàn)室的另一頭就能看到。它配有微電腦芯片，可以在內(nèi)存中設(shè)置3種倒計時間。只需將三種最常用的時間編入程序，以后就再不用設(shè)置倒計時間了。倒計時間范圍是99分55秒到1秒。在達(dá)到零秒時，計時器便開式正數(shù)計時來顯示從報警后開始的時間。
 

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.

在倒計時間達(dá)到10秒時，LED屏幕上每秒鐘便會閃爍獨(dú)特的綠色燈光。在達(dá)到零秒并響起警報后會閃爍紅色燈光。警報聲音有三個開關(guān)位置，在嘈雜地區(qū)可以將聲音設(shè)置為高分貝，在安靜環(huán)境中設(shè)置低分貝，還可以設(shè)置靜音、僅使用閃爍的LED視覺操作。
 

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.

為了確保精度，每一只編有序列號的Traceable?產(chǎn)品都配有通過A2LA認(rèn)證（A2LA與CNAL認(rèn)證相互認(rèn)可）的ISO 17025校準(zhǔn)實(shí)驗(yàn)室授予的證書，它表示產(chǎn)品可以追溯到NIST（美國國家標(biāo)準(zhǔn)與技術(shù)研究院）制定的標(biāo)準(zhǔn)。這件計時器采用磁性背板，因而可以放置到任何金屬表面上，比如放到孵化器或水浴槽上。它還配有一只翻開式座架、一只彈簧固定件，用來夾持在筆記本/書寫板上，此外還有一只孔眼，以便用掛繩來懸掛到墻上。它的精度為0.01%，配有兩節(jié)AAA堿性電池。計時器的尺寸為88.9 x 57.2 x 15.8毫米，重71克。

 

 
 

Traceable? Flashing LED Alert

Big-Digit Dual Channel Timer

Traceable?閃爍LED顯示大數(shù)字雙通道計時器
 

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.

這種計時器可以分別針對兩項(xiàng)活動而設(shè)置從99小時59分59秒到1秒鐘的倒計時間。它的分辨率為1秒，精度0.01%。每個通道配有不同的電子警報和視覺指示，在達(dá)到零秒時便會發(fā)出警報和指示。警報可以關(guān)閉，或者在1分鐘后自動停止。
 

Automatic or programmable memory自動記憶或編程記憶
 

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.

這款計時器采用微電腦芯片，對于重復(fù)計時可以將兩種倒計時間設(shè)置到內(nèi)存記憶中，它能恢復(fù)上一次的倒計時間設(shè)置。顯示屏采用1.6厘米高的LCD大數(shù)字，六米開外就能看到。
 

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.

到倒計時間達(dá)到10秒鐘時，每個通道便會每秒鐘閃爍綠燈。在達(dá)到零秒、警報響起后閃爍紅色燈光。警報聲音有三個開關(guān)位置，在嘈雜地區(qū)可以將聲音設(shè)置為高分貝，在安靜環(huán)境中設(shè)置低分貝，還可以設(shè)置靜音、僅使用LED閃爍的視覺操作。
