1. FEATURES

* Master meter is a professional PH/mV METER.

PH range : 0 to 14 PH x 0.01 PH.
mV range : -1999 mV to 1999 mV.

* DPHC2001 can be plugged with the optional

Conductivity and TDS probe, ( YK-200PCT )
Conductivity probe, ( YK-200PCD )

Dissolved Oxygen probe, ( YK-200PDO )
to be a professional Conductivity meter, TDS ( Total
Dissolved Solids) meter , or Dissolved Oxygen meter. After
plugging in the new probe, no new calibration procedures are
required. ** PLUG & PLAY FUNCTION**

* The instrument is with mV ( millivolt ) function for

mV measurement ( Be plugged with optinal ORP probe
ORP-04 to be a professional ORP meter)

* Wide manual temperature compensation adjustment

can be easily operated by push button on the front panel.

* Optional ATC (Automatic Temp. Compensation) probe is

available for PH measurement.

* Microprocessor circuit assures high accuracy and reliable

performance.

* The instrument is patented with it's intelligent design concept.
* Large LCD, dual function display.
* Records Maximum and Minimum readings with recall.
* Data hold.
* Auto shut off saves battery life.
* Powered by 006P DC 9V battery.
* RS 232 computer serial interface.

circuit.

* 蚓 or 蚌 can be converted by push button on the front panel.
* PH calibration is easily to be done by push button on the

front panel.

* Using the durable, long-lasting components and a strong

lightweight ABS-plastic housing case.

* PH function with high input impedance avoids measuring

error.

* Wide applications: water conditioning, aquariums, beverage,

fish hatcheries, food processing, photography, laboratory,
paper industry, plating industry, quality control, school &
college.
