Electrochemistry Meters

	Series 150 All-in-One E-Chemistry Meter for pH, DO, and COND. Able to perform each test simultaneously for rapid results and no hassles. »
	pH 200 For pH / redox measurement and temperature measurement (Pt1000 or NTC 30kOhm). The water-tight housing complies with IP67. »
	COND 200 For Conductivity, Total Dissolved Solids(TDS), Salinity and Temperature measurement. The water-tight housing complies with IP67. »
	DO 200 For Oxygen Concentration, Saturation, Partial Pressure and Temperature Measurement. The water-tight housing complies with IP67. »

The Series 150 and Series 200 Electrochemistry instruments are rugged, high performance handheld meters that are specifically designed for use in both the laboratory and the field.
The meters come standard with the following features:

• Waterproof housing with built-in storage compartment for probes.
• A built-in support arm can be flipped up to suspend the meter on nearby objects, such as pipes or branches.
• A simple user interface for easy meter operation both outdoors and in the laboratory.
• The automatic Hold function which “freezes” stable measuring data in the display and indicates the presence of reliable and reproducible results.
• The internal memory allows storage of 20 data sets to facilitate subsequent evaluation.
• The integral automatic switch-off feature, varying from 1 to 120 minutes, to preserve the battery life of the units.

The power consumption of all three units has been optimized. As a result, the 4 x 1.5 V integrated batteries have an operating life of up to 15,000 hours, depending on the version.

Electrodes / Measuring Probes

The wide variety of high-quality electrodes and measuring probes for the Series 200 meters makes them suitable for almost any application in water analysis, industry and research. pH combination electrodes made of glass or plastic, with a gel or liquid electrolyte, as well as various temperature sensors (NTC 30kOhm, Pt1000) are considered standard for pH meters. Redox electrodes made of plastic with gel electrolyte and platinum tip have a long life and are easy to use.

The galvanic, membrane-covered oxygen sensor with built-in temperature sensor allows instant measurement without the need for time-consuming polarization. The sturdy, soil resistant 4-pole conductivity measuring cell with graphite electrodes is ideal for use in industrial process and waste water analysis. The electrode‘s robust construction allows routine measurement in temperatures 0 to 80 °C (32 to 176 °F) and up to 100°C, (212 °F) for short periods.
