Automatic Temperature Compensation from 0 to 150 °C (32 to 302 °F) for pH & ISE and 0 to 200 °C (32 to 392 °F) for Conductivity
Standard Onboard datalogging offers realtime and historical trends for all process parameters on one or two channels (depending upon analyzer configuration) for up to 30 days time. This data can be downloaded to any USB stick for further data analysis and workup with programs such as Excel. In addition, on the local display you can view graphing and trending for this realtime data as well as review recent data sets up to 30 days back.
The following links provide examples for visualization of some common weak base and weak acid species where the total ISE can be determined:
- Total Ammonia (NH3-N, or total ammonia as nitrogen)
- Total Fluoride (Total HF, or unreacted fluoride)
- Total Cyanide (Total HCN, or unreacted cyanide)
- Total Sulfide (Total HS, or unreacted sulfide)
All 56 analyzers ordered in the dual ISE/pH configuration can determine total ISE. This means that you can display, output and use for control purposes the free ISE and total ISE such as total ammonia (NH3), total fluoride (HF), total cyanide (HCN) or total sulfide (H2S). A link is provided below that summarizes the 56 analyzer capabilities to compute the total ISE present from the free ISE measurement (from the ISE sensor), the pH value (from the pH sensor) and the process temperature:

* Ion selective measurement type must be set at time of purchase at ASTI factory. Transmitters configured for ISE measurement not sold separately but rather only as part of complete ISE system including ISE transmitter AND ISE sensor supplied complete from ASTI factory. ISE measurement must be validated for feasibility by ASTI prior to sale.
