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.

PEI Body
PEI is suitable for a wide range of applications and excels in field measurements due to its durability. The shielding around the spherical glass tip minimizes breakage due to accidental bumping or dropping of the electrode. PEI is a high quality plastic that is chemically resistant to many aggressive chemicals.

Built-In Temperature Sensor
HN/012302 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.
|
