Waterproof pH Meter G1501 with alarm function including pH electrode GE114-WD

With the development of the new G1000 series is aware of the concentration on the essential functions of the measurement technology. The pure measuring with focus on precision, speed and reliability, packed in a compact housing enables the excellent price/performance ratio, Made in Germany. The new hand-held measuring devices are further enhanced by its ergonomic design, the dust-and waterproof design according to IP65/67 and the illuminated display. The compact pH meter is the alternative to pH-sticks on the one side and to elaborate middle-class devices on the other. The G 1501 also enables Redox (ORP) Measurement (with temperature compensated Ag/AgCl conversion from the reference system in accordance with DIN 38404 part 6, as hydrogen system table 1) and automatic temperature compensation with connected Pt1000 temperature sensor for pH and mVH. And an optical and visual alarm signal (min/max) is also included. This text is machine translated.
