  • Hobo Bluetooth Low Energy Ph And Temperature Data Logger - China

    price: contact company for price

    The HOBO MX2501 pH and Temperature Data Logger is designed for long-term monitoring of pH in estuaries, lakes, streams, rivers, and oceans.

    Leveraging Bluetooth Low Energy® (BLE) technology, the MX2501 pH Logger communicates wirelessly with the free HOBOmobile® app on iOS and Android devices making logger setup, calibration, and data offload quick and easy.

    A guided pH calibration process on the HOBOmobile app makes an otherwise complicated process easier to follow.

    This affordable and compact logger dramatically cuts the time and effort needed to collect field data, while also offering higher resolution data.

    NOTE: pH electrodes should always be stored in storage solution when not deployed.

    Highlighted Features

    Accuracy ±0.10 pH units within ±10°C of temperature at calibration ±0.20 mV

    Resolution 0.01 pH 0.02 mV

    Response Time 1 minute typical to 90% at constant temperature in stirred water

    Sample Ionic Strength ≥ 100 µS/cm

    Temperature Sensor

    Range -2° to 50°C (28.4° to 122°F)

    Accuracy ±0.2°C (±0.36°F)

    Resolution 0.024°C at 25°C (0.04°F at 77°F)

    Response Time 7 minutes typical to 90% in stirred water

    Logger

    Operating Range -2° to 50°C (28.4° to 122°F) — non-freezing

    Buoyancy Fresh water: 13.6 g (0.48 oz) negative

    Salt water: 19.6 g (0.69 oz) negative

    Waterproof To 40 m (131.2 ft)

    Water Detection Water conductivity level of 100 µS/cm or greater is necessary for reliable detection of water.

    Deionized water or water below 100 µS/cm may not be detected.

    The water conductivity circuit may not reliably detect water that has frozen around the electrodes, i.e. below 0°C (32°F).

    Radio Power 1 mW (0 dBm)

    Transmission Range Approximately 30.5 m (100 ft) line-of-sight in air

    Wireless Data Standard Bluetooth Low Energy (Bluetooth Smart)

    Logging Rate 1 second to 18 hours

    Logging Modes Fixed interval (normal, statistics) or burst

    Memory Modes Wrap when full or stop when full

    Start Modes Immediate, push button, date & time, or next interval

    Stop Modes When memory is full, push button, date & time, or after a set logging period

    Time Accuracy ±1 minute per month 0° to 50°C (32° to 122°F)

    Battery Type One AA 1.5 Volt, user-replaceable

    Battery Life 1 year typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always On selected in software.

    2 years typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Off Water Detect enabled in software.

    3 years typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off selected in software.

    Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life.

    pH Electrode Typical Minimum Life 6 months in sample with ionic strength ≥ 100 µS/cm

    Memory 152 KB (43, 300 measurements, maximum)

    Full Memory Download Time Approximately 60 seconds; may take longer the farther the mobile device is from the logger

    Dimensions 22.86 x 4.27 cm (9.0 x 1.68 inches)

    Weight 268.2 g (9.46 oz)

    Wetted Materials Logger: PVC housing and sensor end cap, polycarbonate closure caps and mounting end cap with a TPE switch

    pH electrode: plastic-bodied with Pellon® junctions and gel electrolyte, glass pH sensor bulb

    Environmental Rating IP68

    CE Compliant The CE Marking identifies this product as complying with all relevant directives in the European Union (EU).
