1. FEATURES

* Conductivity/TDS ( Total Dissolved Solids ) Meter

+ PH Meter, multi functions & intelligent features.

* Conductivity includs 2 ranges : 2 mS, 20 mS.

TDS has 2 ranges : 2,000 PPM, 20,000 PPM. Temperature measurement range from 0 - 60 蚓 / 32 - 140蚌.

* Conductivity/TDS meter build in automatic temperature

compensation circuit, adjustable between 0 to 5.0% per 蚓.

* Conductivity/TDS meter uses carbon rod electrode with

long life using separated pobe is convenient for remote measurement.

* PH meter has mV ( millivolt ) function for

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

* PH meter with wide manual temperature compensation

adjustment and optional ATC (Automatic Temp. Compensation) probe is available.

* Microprocessor circuit, intelligent function. * Records maximum and minimum readings with recall. * Data hold. * Auto shut off saves battery life. * RS 232 PC serial interface. * Temperature function with 蚓 & 蚌 display unit.
