Introduction to the U-50 Series

Horiba manufacture water quality meters that vary from inexpensive pocket meters to professional meters designed for field or laboratory use. As part of the professional, field-use range, the U-50 series measure 11 crucial water quality parameters using a single sensor head. The U-50 series is overflowing with features that make testing groundwater and surface water as straightforward as possible.

The series is comprised of seven instrument types and a total of twenty instrument and cable variations. The impressive assortment of options can appear overwhelming. To help find the best U-50 for your application, our scientists prepared a complete overview of the features and specifications of the series. 

 U-50 Series Key Features

Figure 2 Multiple parameters measured
via a single sensor head.

• Multiple Sensors: Multiple sensors within a single, rugged sensor head allow for seamless measurement of 11 parameters simultaneously.
• Easy to Read, Backlit LCD: All 11 parameters are listed on the screen simultaneously.
• One-Hand Operation: The U-50 series digital control unit can be held in one hand for straightforward operation.
• Rugged: The handheld unit features a shock-resistant cover designed to withstand rough treatment in the field. The sensor head is constructed using chemical resistant materials.
• Waterproof: When the sensor cable is fitted, the U-50 series is rated to JIS level 7. Meaning water shall not enter the enclosure when it's immersed under defined conditions (immersion-resistant).
• On-screen Icons: On-screen icons such as battery power, GPS, USB and probe unit connectivity ensure ease of use.
• Automatic Calibration: An easy auto-calibration feature provides hassle free calibration of pH, conductivity, dissolved oxygen, depth and turbidity.
• User-Selectable Display Units: Selectable measurement units allow users to report data easily without manually converting data to desired units.
• Minimal Maintenance: Minimum dissolved oxygen sensor maintenance thanks to the screw-on type membrane cap.
• Replaceable Electrodes: The pH and ORP electrodes can be replaced individually – at a fraction of the price of a new sensor.
• Auto-Hold: The handheld unit features automatic hold, freezing average data values on the screen for easy verification and more time to transcribe data.
• Data Management: The unit features a USB connection for easy data transfer to a PC (USB sold separately with included software).
• GPS: GPS enabled units record latitude, longitude and other important location data with individual measurements – this is especially useful for environmental surveys.

U-50 Series Applications

The U-50 series are robust and thrive in fieldwork ground and surface water testing applications. Examples of use include;

• Measurement at drainage ditches
• Tests from wharves or marine vessels
• Measurement in marshes
• Surface water environmental surveys in oceans, lakes and rivers; and
• Groundwater analysis from an intake.

Conclusion

When it comes to water quality, the list of parameters the U-50 series does not measure is probably shorter than the list it does! The U-50 series, with its 11 critical water quality parameters, a single sensor head, intuitive software and optional PC connectivity, offers the ultimate selection of field water quality assessment tools.
