美国YSI 550A溶氧仪，YSI550A便携式溶解氧测量仪
Measure temperature and dissolved oxygen simultaneously using highly accurate thermistors and YSI's proven polarographic technology for dissolved oxygen.测量温度和溶解氧溶解氧同时使用高度精确的热敏电阻和美国YSI已探明的极谱技术。 The fastest DO response times on the market.市场上最快的溶解氧的响应时间。
Measurements are fast and easy with one-hand operation, an easy-to-use backlit display, automatic push-button calibration, and a weighted, quick-sinking probe.测量快速，单手操作，易于使用的简单背光显示屏，自动按键校准和一个加权，快速下沉的调查。 The YSI550A该YSI550A DO has a built-in calibration chamber, low-battery indicator, direct salinity, and altitude compensation.溶解氧有一个内置的校准室，低电池指示器，直接盐度，并高度补偿。 The instrument provides simultaneous readings of oxygen and temperature.该仪器提供的氧气和温度的同时读数。 Dissolved oxygen readings are automatically compensated for temperature.溶解氧读数自动补偿温度。
美国YSI 550A溶氧仪Screw-on cap membranes make membrane changes easier than ever.螺丝帽膜使细胞膜上的变化比以往更容易。 The PE membranes are also faster responding and require far less flow dependence.体育膜也需要更快的响应，并大大减少流量的依赖。
The replaceable electrode decreases any down time due to old or damaged electrodes.更换电极的任何停机时间减少因旧的或损坏的电极。 Simply unscrew the old electrode, replace it with a new one, and calibrate!只需拧下旧的电极，更换一个新的它，校准！ No need to send it in or to replace the whole cable assembly.没有必要将其发送或更换整个电缆组件。 The cables are now even stronger!该电缆是现在甚至更强！
