(-18 - 60°C) • Operation Temperature Range: 40 to 120 °F (4 - 49°C) • Humidity: 85% at 106 °F (41 °C) • Environmental: IP67, dustproof and waterproof Note: 1. Specifications are subject to change without notice with Pyxis’ continuous development. -
Page 6: Pyxis Major Features
Main features include: ⚫ The SP-800 is pre-calibrated for measuring turbidity in the range of 0 to 200 NTU. ⚫ Automatically select the primary wavelength according to the method selected and switches to the secondary wavelength to extend the primary measurement range. -
Page 7: Optional Accessories
The light shield cover should be in the closed position during storage, transportation, and measurements, especially during the turbidity. When turned on, the SP-800 carries out self-diagnosis including checking the performance of a variety of optical devices. The light shield door shall be at the closed position to shield interference from ambient light during self-diagnosis. - Page 8 Figure 2 Open and Close the Light Shield Cover Warning Magnetic sensitive devices, including but not limited to, credit cards, watches, hard disks, should be keep at a distance of at least 2 inches from the Light Shield Door to avoid possible damage and/or loss of information recorded.

3.4 Single-Vial Procedure 1. Place the sample vial filled with the water sample in the SP-800 sample vial compartment and press the ZERO button. The SP-800will display the page shown in Figure 7. 2. Take the sample vial out and add the reagent to the sample vial. -
Page 15: Multiple Timing Steps Method
Figure 8. Multiple Timer Method In order to show the concentration-time curve as shown in Figure 8 during the last timing step, The SP-800 must be zeroed using the prepared blank before the last timing step. Thus, the last timer button will not be selectable until the SP-800 has been zeroed using the prepared blank. -
Page 16: Low Range, Direct Reading Chlorine Dioxide, 0 To 35.0 Ppm
Direct Reading Bleach Percent Method, 0 to 15% The SP-800 has a 365nm UV LED and other deep blue LEDs that can be used to directly measure bleach concentration in the range of 0 to 15%. No reagent is required for the method and the displayed result is the sodium hypochlorite concentration in percentage. -
Page 17: Slope Calibration
The following steps are used to calibrate a method: Use a calibration standard of known concentration. Follow the steps required by the method and note the value reported by the SP-800. If the measured value differs from the known standard value, Press the CONFG button to launch the method configuration page. -
