Description
Hanna® Laboratory Research Grade Benchtop pH/mV Meter with pH Electrode and Temperature Probe, 0.001 pH Resolution
Features:
- Highly customizable user interface—includes showing measurements in various modes with or without GLP information, real-time graphing, logging data, adjustable calibration stability criteria (fast, moderate, and accurate), programmable alarm limits (inside or outside)
- Color graphic LCD—on-screen help, graphic and custom color configurations, real-time graphing, virtual keys for intuitive user interface
- Built in barometer—provides pressure compensation for all DO measurements via built-in pressure transducer (can be calibrate to a single point)
- Capacitive touch—sensitive touch buttons for accurate keystrokes while navigating menus and screens; four dedicated keys for routine operations including calibration and switching modes plus four virtual keys that change based on use; no worry of clogged buttons
- Choice of calibration—automatic buffer recognition, semiautomatic, and direct manual entry pH calibration options available for calibrating up to 5 points from a selection of 8 standard buffers and up to 5 custom buffers
- GLP Data—user can view calibration data and calibration expiration at touch of a key; includes date, time, buffer/standards used, and slope characteristcs; offset for pH electrodes also displayed
- CAL Check™—alerts user to potential problems during calibration of pH electrode; indicators include Electrode Dirty/Broken, Buffer Contaminated, electrode response time and overall probe condition as a percentage based on offset and slope
- Data logging—automatic, manual, and auto-hold logging (up to 100 lots with 50,000 records maximum/lot, with up to 100,000 total data points) ; automatic logging features option to save data according to sampling period and interval
- Data transfer—transfer data to PC via USB cable and HI92000 software (sold separately)
- Contextual help—dedicated Help key provides clear tutorial messages and on-screen directions to guide users through set-up and calibration; information displayed relative to setting or option being viewed
- Warranty—2 years for meter; 6 months for probes
