Benchtop pH/ORP/lon Meter PH-920 PH-930

Description

Benchtop pH/ORP/lon Meter PH-920 PH-930

pH：

1. 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.

2. Automatic electrode diagnosis shows the pH slope and offset.

3. Automatic temperature compensation ensures accurate readings over the entire range.

4. Calibration due alarm prompts user to calibrate the meter regularly.

ORP:

1. 1 point offset calibration allows adjusting the displayed value to a known standard.

2. Relative and absolute millivolt modes ensure the reliable ORP measurements. Ion Concentration(For PH-930).

3. 2 to 5 points calibration, including the 8 concentration points can be selected.

4. Direct ion concentration readout simplifies the measurement process.

5. Automatic electrode diagnosis shows the calibration points and slopes.

6. Selectable concentration units(ppm, mg/L, mol/L, mmol/L) and ionic valency.

General Features：

1. Auto-Read function senses and locks the measurement endpoint.

2. Setup menu allows setting the pH buffer set, number of calibration points, resolution, stability criteria, temperature unit, date and time, etc.

3. Reset function automatically resumes all settings back to the factory defaults.

4. Expanded memory stores or recalls up to 500 data sets.

5. USB communication interface for data transfer and timed interval readings.
