USB DrDAQ® 2011 Data Logging Kit - PP707While 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 Redox/ORP (Oxidation/Reduction) (BNC shared with pH) | ±2 V @1012 Ω | 1.2 mV | Sensor-calibration dependent Resistance (screw terminal) | 0 to 1 MΩ | 250 Ω @ 10 k | 5% External sensors (3 x FCC68 4/4) | Measure 0 to 2.5V (Also supply power to external sensors and identify sensor type via ID resistor) | 0.1 mV | 1% Oscilloscope spectrum analyser channel (BNC) | ±1.25 V, ±2.5 V, ±5 V, ±10 V@1M Ω | 8 bits | ±3% (DC) Sound waveform | ±100 | ±0.2 | Not calibrated Sound level | 55 to 100 dBA | 1 dBA | 5 dBA Temperatur
