multiparameter ph meter price portable digital pH/dissolved oxygen meter with a large backlit LCD display

903P

Characteristics:

pH Mode:
1. Multiparameter portable pH/DO meter is equipped with a large backlit LCD display.
2. 1 to 5 points push-button calibration with auto-buffer recognition.
3. Selectable pH buffer standard (USA/NIST/DIN) or using the custom calibration solutions.
4. Automatic electrode slope display helps user decide whether to replace sensor.
ORP Mode:
1. Single point offset calibration allows adjusting the displayed value to a known standard.
2. Relative and absolute millivolts measurement modes provide accurate ORP readings.
Dissolved Oxygen Mode:
1. 1 or 2 points calibration using the air-saturated water and zero oxygen solution.
2. Manual salinity and barometric pressure compensation improve the measurement accuracy. 
Other Features:
1. Automatic Temperature Compensation provides accurate reading over the entire range.
2. Calibration Due Reminder prompts user to calibrate the meter regularly.
3. Stability indicator automatically shows current measurement status.
4. Auto-Hold function freezes stable measured value for easy viewing and recording.
5. Manual temperature calibration corrects temperature deviation.
6. Selectable temperature unit (°C or °F) meets different application requirements.
7. Automatic electrode diagnosis shows zero point offset and slope of the electrode.
8. Help message as a operational guide that helps you quickly begin using the meter.
9. System menu allows setting the 11 parameters, including the number of calibration points,resolution, stability condition, measurement unit, etc.
10. Reset feature automatically resumes all parameters back to factory default settings.
11. Expanded memory stores and recalls up to 500 readings.
12. Built-in real-time clock stamps stored data to meet GLP standard.
13. Stored data can be transferred into computer by USB communication interface.
14. Multi-mode power scheme (battery, power adapter, computer's USB port) ensures that use the meter smoothly.
