- Oxygen partial pressure, oxygen concentration, oxygen saturation and temperature measurement
- Automatic absolute air pressure measurement
- Auto Hold function
- Easy calibration against the oxygen in the air
- Self-polarising oxygen probe, allows instant measurement after the system is switched on.
- Low bat and battery change indicator
- Sensor evaluation in the display
The new microprocessor-controlled SensoDirect hand-held meter range from Aqualytic® meets the day-to-day demands on sturdy and reliable systems for the measurement of pH or redox, conductivity/TDS and dissolved oxygen.
The water-tight housing in compliance with IP67 and equipped as standard with protective armouring ensures reliable operation even in extreme ambient conditions. The support can be flipped up to hang the meter on pipes or branches.
The direct, convenient and easy-to-understand user prompt with the required configuration options for all three systems facilitates the use of the meters both outdoors and in the lab.
The automatic Hold function ”freezes” stable measuring data in the display and indicates to the user the presence of stable and reproducible results.
The internal memory permits storage of 20 data sets to facilitate subsequent evaluation. The integral auto switch-off feature that can be set from 1 to 120 minutes, increases the operating life of the units.
The power consumption of all three unit versions has been reduced to a minimum. As a result, the 4 x 1.5 V integrated batteries are good for an operating life of up to 10,000 hours, depending on the unit version.
Aqualytic® Electrodes/Measuring Probes
 A wide variety of high-quality electrodes and measuring probes for the SensoDirect meters make the units suitable for almost any application in industry and research.
Single-rod measuring chains made of glass and plastic, with gel or liquid electrolyte, as well as various temperature sensors (NTC 30kOhm, Pt1000) are considered standard for modern pH/ORP Process Controllers.
Redox electrodes made of plastic with gel electrolyte and platinum tip are hardwearing and easy to use. The amperometric, diaphragm-covered oxygen sensor with integrated NTC allows instant measurement without the need for time-consuming polarisation.
The sturdy conductivity measuring cell with two graphite electrodes is ideal for use in the field of service and waste water analysis.
