LUTRON PH-207 Digital PH Meter with PE-03 sensor *
Microprocessor circuit assures high accuracy and provides
special functions and features.
* Super large LCD display with contrast adjustment for best
viewing angle.
* Dual function meter's display.
* Heavy duty & compact housing case.
* Records Maximum, Minimum and Average readings with RECALL.
* Data hold.
* Auto shut off saves battery life.
* Operates from OO6P DC 9V battery.
* RS 232 PC serial interface.
* Used the durable, long-lasting components, including a
strong, light weight ABS-plastic housing case.
* Multi-measurement : PH, mV, Temperature.
* Temperature function for °C or °F be selected by push
button on front panel easily.
* Show the PH & temperature values on the same LCD display
at the same time.
* High input impedance avoid measuring error.
* Wide manual temperature compensation range from 0 °C to
100 °C , high accuracy.
* Auto temperature compensation range via. the external
optional temp. probe.
* The values of "Manual temp. compensation" are reading from
the LCD display directly, no errors & easy operation.
* With the optional temp. probe for automatic temp.
compensation of PH function or temp. measurement.
* The instrument build in mV(milli volt) measuring function,
letting you make ion-selective, ORP, and other precise mV
measurement.
* Wide applications: water conditioning, aquariums,
beverage, fish hatcheries, food processing, photography,
laboratory,paper industry, plating industry, quality
control, school & college, water conditioning. |
