Waterproof Portable pH/ORP/ISE Meter – IC-HI98191

Features:

pH CAL Check: Alerts user to potential problems during calibration including when to clean electrode and possible buffer contamination.
Displays overall probe condition based on offset and slope after calibration.
ISE direct concentration readout in a choice of concentration units.
Automatic Temperature Compensation.
Five point pH calibration with seven standard buffers and five custom buffers.
Calibration timeout to alert the user at a defined interval when the calibration has expired.
Log on demand feature: Store measurement data at the press of a button, allowing the user to record and save up to 200 samples (100 for pH and 100 for mV)
AutoHold – freezes reading on display upon stabilization
GLP features include date, time, pH calibration buffers, offset and slope.
Multiple language selection.
200 hour battery life with battery level displayed on measurement screen.
Menu driven for ease of use with virtual-key extended functionality.
PC connectivity via a sealed opto-isolated micro USB and HI92000 software
The high contrast graphic LCD is easy to read outdoors in bright sunlight as well as in low-lit areas with the backlight. A combination of dedicated and virtual keys allows easy, intuitive operation in a choice of languages.
