"HALO" Water pH-Meter
Take laboratory grade pH and temperature measurements using your smart phone or tablet
HALO Wireless Water pH Meter has a glass body, spherical tip, and has a built-in temperature sensor. All readings are transmitted directly to your Apple or Android device or the edge blu.
- Take laboratory grade pH and temperature measurements using your smart phone or tablet
- Easily connect to the Hanna Lab App at the press of a button via Bluetooth wireless technology
- Group your data by time or notation. Email it for storage or share it with friends or colleagues
Delivery equipment
HALO is supplied with hood, calibration solutions ph 7:01 and ph 4.01 in sachet, cleaning solution electrodes in sachet, battery, quality certificate and instruction sheet.
Note: All units displayed in the images not included in this equipment are tools or configuration accessories to be purchased separately.
The HALO Wireless Water pH Meter incorporates Bluetooth® Smart technology with an application-specific design. There are several features that make it ideal for measuring the pH of water.
| |
General Purpose Glass Formulation
General Purpose (GP) glass provides the best response over the entire pH range and can be used for a wide range of applications.
|
| |
Built-In Temperature Sensor
HN/010482 features a built-in temperature sensor for temperature measurement and compensation.
|
| |
Spheric Glass Tip
The spheric bulb is for general purpose use within laboratory environments and applications that measure aqueous solutions due to its large surface area.
|
| |
Real-Time Data
Display of pH and temperature updated every second. Readings are automatically saved to a history file every hour, limited only by the available memory on the device.
|
| |
Fluid, Dynamic Graphing
Measurements can be displayed alone on the display, with tabulated data, or as a graph. The graph can be panned and zoomed with pinch-to-zoom technology for enhanced viewing.
|
| |
GLP (Good Laboratory Practice)
Displays date and time of current calibration, offset, and average slope, along with calibrated buffers, mV values, temperature and slopes between each buffer.
|
| |
Calibration Reminder & Measurement Alarms
The Hanna Lab App alerts you when HALO needs calibration or if a measurement threshold is exceeded.
|
