HOBO Bluetooth Low-Energy pH and Temperature Data Logger, MX2501
Description
- High accuracy—within ±0.10 pH units in underwater environments
- Replaceable battery and pH electrode cartridge
- Guided pH calibration following on-screen prompts in mobile device app
HOBO pH/temperature data loggers are ideal for long-term underwater monitoring of pH in large tanks or bodies of receiving waters. These affordable, compact loggers dramatically cut the time and effort needed to collect field data, while also offering high-resolution measurements.
All data retrieval, logger setup and calibration is performed wirelessly with your mobile device using Bluetooth Low Energy® technology and the free HOBOmobile® app (available for Android and iOS devices). A guided pH calibration process on the HOBOmobile app makes calibrating simple and easy to follow. Download the app for free at the Google PlayTM or App store.
Maintenance is minimal other than routine cleanings and calibrations recommended about every 7 days. The anti-biofouling copper guard (stock # 28541) provides extra protection against biofouling during use, while still allowing proper water flow to the sensor. Use standard 4, 7, and 10 pH buffers for calibration (sold separately). Replace the double-junction potentiometric pH electrode sensor cartridge (stock # 28539) every six months.
Includes: battery, electrode in storage solution, and detachable anti-biofouling copper guard.
- Range: 2.00 to 12.00 pH (-512 to 512 mV)
- Accuracy: +/-0.10 pH units within +/-10°C of temp. at calib.(+/-0.20 mV)
- Resolution: 0.01 pH (0.02 mV)
- Operating conditions: 28.4 to 122°F (-2 to 50°C), submersible to 131.2' (40 m)
- Electrode life: 6 months typical
- Sample interval: 1 minute to 18 hours programmable
- Data storage: 21,700 sets of pH and temp. measurements; record trigger options include immediate, delayed, scheduled start (via Bluetooth up to 100' transmission distance)
- Wetted materials: PVC, polycarbonate, TPE, plastic, Pellon® nylon, glass
- Power: One AA 1.5V battery (replaceable), 1 to 3 year lifespan
- Dimensions: 1.7"Dia x 9"L
