pH/mV/T Meter (0,01 pH) with CAL Check
Benchtop meter features CAL Check™, data logging capability, and USB port for computer connectivity
HN/002221-02 - Benchtop pH/mV Meter with CAL Check
The HN/002221-02 is an affordable pH/mV benchtop meter that features automatic pH calibration up to five-points that can be performed using seven standard buffers.
All pH measurements are compensated for temperature effect automatically with the supplied HN/007662 temperature probe.
The HN/002221-02 can also measure oxidation reduction potential (ORP) in the mV range using ORP electrodes.
The HN/002221-02 offers many features including CAL Check, data logging up to 100 records, GLP (Good Laboratory Practice) capabilities, and PC connectivity via USB to provide users with a simple way to organize and manage their data.
- Automatic Temperature Compensation
- GLP and Logging Capabilities
- CAL Check
Details
The HN/002221-02 pH/mV benchtop meter features CAL Check, data logging capability, and USB port for computer connectivity.
Readings for pH can be manually or automatically compensated for temperature variations with the separate HN/007662 temperature probe from -20.0 to 120.0°C.
As a pH meter, the HN/002221-02 can perform up to a five-point pH calibration with seven standard buffers (1.68, 4.01, 6.86, 7.01, 9.18, 10.01, and 12.45).
The HN/002221-02 can also measure using ORP electrodes (pH channel input), due to the capability to measure mV with a resolution up to 0.1 mV.
The memory of the HN/002221-02 allows for storage of up to 100 log-on-demand records. Logged data, along with Good Laboratory Practice (GLP) data, can be recalled on the meter itself or transferred to a PC via USB cable.
Features at-a-glance
Simple User Interface
- Operation is simple with limited features that only require the use of a couple of buttons
- Readings are easy to view on the large, clear display
CAL Check
- Exclusive CAL Check diagnostics system ensures accurate pH readings every time by alerting users of potential problems during the calibration process
- The CAL Check system eliminates erroneous readings due to dirty or faulty pH electrodes or contaminated pH buffer solutions during calibration
- After the guided calibration process, the probe condition is evaluated and an indicator is displayed informing the user of the overall pH electrode status
Automatic Calibration
- Automatic pH calibration can be performed at up to 5 points using 7 standard buffers (1.68, 4.01, 6.86, 7.01, 9.18,10.01, and 12.45)
GLP Data
- The calibration data for each channel including date, time, standards used, offset, and slope can be accessed when the instrument is in pH measuring mode
HN/01131P pH Electrode
- The HN/002221-02 is supplied with the HN/01131P glass body, double junction, refillable pH electrode with a BNC and pin connector
- This design consideration is ideal for laboratory samples, liquid samples, and high temperature samples, as well as general purpose use
Temperature Compensation
- The HN/002221-02 offers manual or automatic temperature compensation of pH measurements over a wide range from -20.0 to 120.0°C
mV mode
- The HN/002221-02 has a mV mode that can be used with ORP electrodes and for relative mV readings
Stability Indicator
- The HN/002221-02 features a stability indicator
- An hourglass appears on the display when there is instability in the reading
- The hourglass disappears once the reading has stabilized
- At that time a reading should be taken or stored
Data Logging
- The log-on-demand feature allows up to 100 data points to be recorded
Data Transfer
- Data can be transferred to a PC with a USB cable and HI92000 software (both sold separately)
