HI-981914 Pool line Professional Waterproof Portable pH/ORP/ISE Meter
HI-981914
This portable meter is ideal for swimming pool maintenance. A handheld device with all the benefits of a bench meter. The meter measures pH, ORP and ISE.
Each meter is supplied complete with sensor, calibration solution, beakers, PC software and connection cable, instruction manual, quick start guide and batteries in a rugged, custom carrying case.
Key features
ISE measurement units: Extensive choice of units to display readings (ppm, ppt, g/L, μg/L, mg/L, M, mol/L, mmol/L, %, w/v, user).
Waterproof - IP67 rated: waterproof, rugged enclosure.
CAL Check™: Alerts users to problems during pH calibration including dirty/broken electrode, contaminated buffer and overall probe condition.
Automatic or manual temperature compensation: pH sensors incorporate a built-in temperature sensor.
Calibration: Up to a five-point pH calibration with seven standard buffers and five custom buffers available.
Approximately 200 hour battery life: Powered by (4) 1.5V AA batteries.
Clear display: Dot matrix display with multifunction virtual keys.
AutoHold: Automatically holds the first stable reading on the display.
Calibration timeout: Alerts when calibration is due at a specified interval.
Connectivity: PC connectivity via opto-isolated micro-USB with HI-92000 software.
GLP: GLP data provides data from previous calibration to ensure Good Laboratory Practices are met.
Intuitive keypad: Most of the available options such as GLP information, help, range, calibration and backlight have a dedicated button.
Waterproof Protection: The meter is enclosed in an IP67 rated waterproof casing and can withstand immersion in water at a depth of 1 m for up to 30 minutes.
About the Backlit Graphic LCD Display
This meter features a backlit graphic LCD with on-screen help. The graphic display allows for the use of virtual keys to provide for an intuitive user interface.
About CAL Check™
Hanna’s CAL Check maintains a history of past calibrations and monitors the pH electrode and buffers during subsequent calibrations for any signs of wide variances due to a dirty or broken electrode or contaminated pH buffers. During calibration, users are alerted to problems should they occur. After calibration, the electrode’s overall condition is displayed as a percentage.
Data Logging
The log-on-demand feature allows users to store up to 200 samples that can later be transferred to a PC with the HI-920015 USB cable and HI-92000 software.
About the HI-72911B pH Electrode
This electrode has a Titanium body. Its Titanium construction provides an unbreakable structure and allows the transfer of heat to the internal temperature sensor for rapid temperature compensation.
The HI-72911B electrode is maintenance free, gel-filled and does not require a fill solution.
