Field water analysis often means changing locations, probes and measurement tasks during the same working day. PRO 595 supports that workflow with a BNC input for pH/ORP electrodes, a banana input for electrode temperature sensors and two DX inputs for interchangeable digital probes.
The instrument helps teams record dependable measurement data in water analysis, aquaculture, river monitoring, well water analysis and wastewater monitoring. It measures pH from -2.00...+16.00 pH, ORP from -2000.0...+2000.0 mV and temperature via Pt1000 or NTC sensors. With DX probes, it can also display parameters such as dissolved oxygen, pressure, humidity, IAQ, photo-radiometric quantities and soil moisture, depending on the connected sensor.
On site, the backlit multilingual dot matrix display, HOLD function, chart view and Min/Avg/Max statistics make readings easy to check. Up to 1 million data sets can be stored with date and time stamp, then read out via USB-C as CSV files without extra software.
The high-impedance BNC input connects pH or ORP electrodes. A 4 mm banana socket supports Pt1000, NTC 10k or NTC 30k temperature sensors integrated in electrodes.
Two 5-pin M12 inputs connect DX series digital probes. Compatible probes cover dissolved oxygen, temperature, pressure, humidity, photo-radiometric quantities, IAQ and soil moisture.
The logger supports automatic recording with selectable intervals, manual single recording and sequential data collection in JSON format with Standard, Multiselect and on hold modes.
The backlit 140 x 160 dot matrix LCD shows large single values, multi-row views, statistical information and graphical chart views for selected parameters.
Configurable alarm thresholds can be assigned to selected measurement channels, with acoustic and optical signaling plus adjustable hysteresis.
The instrument runs on four rechargeable AA NiMH batteries and can also be powered through USB-C using an external 5 Vdc supply.
The multilingual menu supports device settings, favorite functions, protected mode with PIN and selectable measurement units where supported by the connected probe.
