    Specification :

    Design
    The design is quite simple. The basic parts could be assembled and disassembled without any extra tools.
    Moreover, operating the WQL-pH is effortless and timesaving. The robust stainless steel logger provides
    reliable protection and guarantees trouble-free measurements. For logger fixation the included shackle can
    be used. The shackle size matches the logger diameter.

    Huge memory space
    Flash memory for up to 600, 000 data records – measurements over a long period of time depending on the
    interval. Exceeded memory with an interval of ( e.g.) :
    • 1 s after 7 days
    • 30 s after 11 months
    Safe data storage
    Logged data is persistent, also in case of a power failure
    Detailed data recording
    Recorded are: pH, temperature, date/ time and data logger ID number

    Applications
    Monitoring of water resources has become a global challenge with high priority.
    Therefore innovative measuring technology is absolutely essential. Typical
    applications for WQL-pH are characterized by reliable and huge series of
    measurements at multiple measuring points that are difficult to access. In general
    these measurements take place over a long period of time.
    The data Logger WQL-pH is applicable for usage in ground and surface water as
    well as in drinking and waste water.
    Wide application range of WQL-pH:
    • Watershed and wells
    • Rivers, lakes
    • Landfill runoff
    • Construction and restoration projects
    • Pump stations
    • Diggings and boreholes
    • Applied limnology
