Outdoor airvolume4/11/2023 ![]() ![]() Refer to the relevant section of the user guide for wiring instructions. The upper and lower limits can be set by the user via this control function. The control pin can be wired to control a gas concentration between upper and lower concentration limits. This is designed to control generation of a gas such as ozone from an ozone generator. What is the “Control” function (Series 300 & 500 only)? RS232 protocol available upon request for third party software integration. S500: 0-5V Analog output (current reading only), RS232 (current, logged data and instrument control) to PC software via USB adapter. S300: 0-5V Analog output (current reading only) What communication options does the portable monitor have? Note: Once capacity is reached new data will begin to overwrite the oldest logged data. 3 data points per minute) you can log for 2729 minutes.ĭecrease the logging frequency for the ability to log over a longer timeframe. If you are logging every minute for one gas, temperature and humidity (i.e. one data point per minute) you can log for 8188 minutes. If you are logging every minute for one gas (i.e. The Series 500 handheld unit can store a limited number of data points (8188), meaning that the length of time that data can be logged depends upon the frequency and number of data points recorded. How long can I log data for (Series 500 only)? See a range of frequently asked questions on calibration here. Aeroqual does not recommend a second factory calibration, but rather replacement after two years of operation. The sensor head calibration should be completed after the first year. All parameters are stored on the sensor head. The base unit does not need to be calibrated. ![]() Only the sensor head needs to be calibrated. *as particulate matter varies in size, unlike a gas molecule, PPM is not a valid unit of measurementĭo I return the instrument for calibration? The portable monitor measures in PPM and applies a conversion factor if you wish to measure in mg/m3. PPM is an absolute measurement, whilst mg/m3 varies depending upon pressure and temperature. What is the PPM to mg/m³ conversion factor? ![]() The PM sensor is compatible with Series 200/300/500 monitors with software version 6.4 introduced in November 2014. However, you are able to connect the optional temperature and humidity sensor at the same time as a gas or particulate sensor head.Ĭan I use the PM sensor head with any portable monitor? You can only connect one gas or particulate sensor head at a time to monitor. How many sensors can I use on the monitor at once? ![]()
