PP707,749-1917,Pico Technology PP707 数据记录仪, 测量最大+70 °C, 相对湿度90%RH, 最大电压5V ,Pico Technology
While the USB DrDAQ DrDAQ data logger unit (RS 749-1914) comes with many built-in sensors, the USB DrDAQ Data Logging Kit PP707 (RS 749-1917) contains additional sensors and probes to enable many other measurments to be taken, therefore allowing further experiments to take place immediately.
| Channel | Range | Resolution | Accuracy |
| pH (BNC) | 0 to 14 pH | 0.02 pH | Sensor-calibration dependent |
