1. Data hold
The PHB series have a simple measurement data lock function, when it is in pH measurement mode, press the HOLD key, the instrument automatically lock the current measured data, when press the key again, instrument returns to measurement mode.
2. Automatic temperature compensation and measurement:
PHB-30 is equipped with temperature sensor, through temperature key, you can browse the current temperature data of the sample, when during pH calibration or measurement, the instrument has the function of automatic temperature compensation.
3. Can replace electrode
Because the chemical properties of pH electrode, the service life is about a year or so, if more than time limit, it can seriously affect the accuracy of the instrument. Electrode sensors of PHB series applies the plugin connection design, you can easily replace it.
4. Manually or automatically shut down:
For the design, in order to effectively save electric energy, we set up the automatic shutdown system for instrument program. After startup, if in eight minutes without any key operation, the instruments will be transferred to standby mode to save electricity.
5. Two keys/automatic calibration:
PHB series with two points buttons calibration function. During calibration, the instrument hints you which style of the PH standard buffer should be used, you only need to press Prompting and dip electrode sensors into the corresponding calibration liquid, press ENTER key, instrument calibrates automatically.
6. Good waterproof properties:
PHB has a good waterproof performance, even in water, it will not be affected, the weight of the instrument is calculated by levitation force, it can float to the top when it is submerged in water.
7. Instrument configuration:
PH standard buffer regent: 1 set ( international version: USA type), 1.5 V button cells 3 quarters.
8. Recognize standard buffer regent automaticly
During calibration period, if you wrong use standard buffer or use the standard buffer which is badly spoiled, instrument will automatically alarms and displays ERROR.
