Product Description

Horiba U-51-2 Multi-Parameter Water Quality Meter (2m Cable)

The Horiba U-51-2 multi-parameter water quality meter is available in seven models which are capable of simultaneously measuring up to 11 parameters. Each model has the ability to measure a different combination of pH, ORP, dissolved oxygen, conductivity, salinity, TDS, seawater specific gravity, temperature, turbidity (LED or tungsten lamp), water depth and GPS.

With an easy-to-read LCD display, Horiba U-51-2 multi-parameter water quality meters can display measurement data from all 11 parameters on the screen simultaneously. Text size can be changed to a larger font and the small control unit is designed for one-hand operation. Auto-calibration allows for hassle-free calibration of pH, dissolved oxygen, conductivity, turbidity and depth with the Horiba U-51-2. These Horiba water quality meters are designed for the field– the cover is shock resistant and the cable can be easily connected and disconnected using the quick-connect fitting.

Data management with the Horiba U-51-2 multi-parameter water quality meter is also very simple. The auto hold function freezes average data values on the screen, giving you more time to verify and transcribe data. Diagnostic functions notify the user of errors and an integral USB connection makes data transfer to a PC quick and easy. Selectable measurement units allow the operator to report data without the need to convert data to desired units of measure.

The Horiba U-51-2 probe houses several sensors in one unit. Multiple sensors allow for the measurement of 11 parameters simultaneously. The field replaceable sensors are chemical resistant and rugged enough for all environmental conditions. A 3-electrode design offers improved stability of the dissolved oxygen sensor and the pH and ORP electrodes can be replaced individually to reduce replacement costs.
The Horiba U-51-2 multi-parameter water quality meters ship complete with pH 4 standard solution (500mL), pH reference internal solution (250mL), DO sensor internal solution set (50mL internal solution, #8000 and #600 sandpaper, syringe), DO membrane space parts set, spanner for DO sensor removal, cleaning brush, calibration cup, back pack, strap, 4 alkaline batters (LR14), silicon grease and instruction manual.

Battery life is estimated under following conditions.
Continuous operation
Using batteries: C-size alkaline dry cells
Ambient temperature of the control unit: 20℃ or more
Backlight off

The precision is defined by measuring the standard solution in the following cases.
Turbidity and conductivity: after four point calibration
pH and DO: after two point calibration
Water depth and ORP: after one point calibration

Metallic parts are made of stainless steel. Immersing in seawater may erode metallic parts.
