Portable pH/lon Meter

Description

Portable pH/lon Meter

Measurement Parameters:

1. PH-320: pH, mV, relative mV, ion concentration, temperature.

2. PH-321: Ion concentration, mV, temperature.

Features:

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.

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

1. 2 to 5 points calibration, including the 8 concentration points can be selected.

2. Direct ion concentration readout simplifies the measurement process.

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

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

General Features:

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

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

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

4. Auto-Power Off effectively conserves battery life.

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

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

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

8. USB communication interface is easy to transfer data to PC.

9. Multi-mode power scheme(batteries, power adapter and USB port) ensures that using the meter smoothly.

Optional Ion Selective Electrodes:

Ammonium(NH4+), bromide(br-), cadmium(Cd2+), calcium(Ca2+), chloride(Cl-), cupric(Cu2+), cyanide(Cn-), fluoride(F-), Iodide(I-), lead(Pb2+), nitrate(NO3-), potassium(K+), silver(Ag+), sodium(Na+), sulphide(S2-) and ammonia(NH3)

Accessories:

PH-320: Meter, PH electrode, temperature probe, PH buffer solutions(pH4.01/7.00/10.01), carrying case.

PH-321: Meter, ion selective electrode, temperature probe, standard solutions (100/1000ppm), ionic strength adjuster and carrying case.
