pH Sensor

**** | pH | mV
Range | 2.00 to 12.00 pH | -512 to 512 mV
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
