MODEL 200SB MODEL 200SB HTO便攜式氚監(jiān)測器
200SB是一款低成本、輕量的便攜式氚監(jiān)測器。前板僅有三個控制鍵,一個“開-關(guān)-樣品”開關(guān)和設(shè)定報警值的開關(guān)。無需零點調(diào)整。200SB在0℃ 至+50℃溫度范圍內(nèi)顯示無零點漂移.大容量泵和快速電子學(xué)的結(jié)合使得此款儀器各種反應(yīng)快速。
SENSITIVITY, RANGE, SPEED OF RESPONSE
靈敏度,量程及反應(yīng)速度
This instrument is useful where measurement sensitivities of the order of 10 μCi/m3 (1 MPCA)
is sufficient, and where wide range, and fast response are needed. This low cost portable
model has a 4 ? digit LCD display for reading from 0 to 19,999 MPCA.
此款儀器適于測量靈敏度要求達到10μCi/m3 (1 MPCA),需要寬量程及快速響應(yīng)的地方,
此低成本型號有4 ? 數(shù)字LCD顯示讀數(shù)從0到19,999 MPCA.
CONVENIENT FOR USE
方便使用
This instrument needs no zero adjustment. It is ready for use by merely selecting the desired
alarm level and activating the instrument power.
此款儀器無需零點調(diào)整,僅需選擇所要的報警水平值并接通電源,就準備使用了。
The initial power surge transient will disappear in a minute; the readings will then be accurate.
初始電浪涌瞬時一分鐘內(nèi)消失,然后讀數(shù)將精準顯示。
GAMMA COMPENSATION
伽馬補償
The use of twin, side by side, or coaxial ionization chambers provides good gamma
compensation in moderate background gamma radiation fields.
使用并列雙室,同軸電離室在中本底伽馬 輻射場提供了很好的伽馬補償.
FAST RESPONSE
快速響應(yīng)
The use of a large pump, 3 liters a minute, together with fast electronics yields an
overall measurement time constant of under 5 seconds.
使用大容量泵,3升每分鐘,加上快速電子學(xué)使得整個測量時間常數(shù)在5秒以下
HTO DISCRIMINATION
氚識別
An HTO discriminating version is available. By addition
of an external desiccant column, this instrument will specifically
measure HTO in the presence of HT, or other radioactive gases.
HTO識別款型有供應(yīng),通過添加外部干燥柱,這款儀器將專門測量以
氚氣或其它輻射氣體形式出現(xiàn)的HTO。
