Sales, Service, & Rentals

The Horiba W-22 is a comprehensive instrument for measuring and monitoring water quality in wells, lakes, streams and ponds. With a variety of cable lengths available, the W-22 is made for easy deployment in difficult field conditions. The unit allows for simultaneous monitoring of up to 8 parameters in real-time, including pH, oxygen reduction potential (ORP), conductivity, salinity, total dissolved solids, depth, turbidity and dissolved oxygen.

Built for Flexibility in the Field

Despite these powerful functionalities, the Horiba W-22's probe is small enough to fit in wells as narrow as 2 inches in diameter. One-touch calibration makes servicing the W-22 in field conditions simple; the device also allows for standard 2-point calibration when higher-precision measurements are required. The unit is powered by a conventional dry cell battery that provides up to 30 days of continuous use and is easy to swap out when required.

A Rugged Performer in Any Condition

From Denmark's Lading Marsh to the Los Chorrilos River of Argentina, the W-22 has proven its mettle in diverse environments across the globe. With a rubber sensor guard to prevent contamination and a stainless steel cover housing the unit's probe, the Horiba W-22 was built with the needs of today's environmental technicians in mind. A heavy-duty Pelican® carrying case comes standard, making it easily transportable without fear of damage. Additionally, the W-22 has been designed to be compatible with a GPS unit, letting you take accurate, time- and location-stamped measurements no matter where you are in the world. Waterproof to IP-67 standards, the W-22 is a rugged performer in any condition.

Powerful Sensors for Fast and Accurate Readings

At the heart of the Horiba W-22 lies advanced sensor technology that makes it ideal for professional and research applications. An optional dissolved oxygen sensor is unique in its class, with a patented galvanic membrane that gives precise readings even in rough waters. All told, the unit is capable of providing up to 8 in-situ measurements at once. With an onboard memory capable of logging an entire month of readings collected at 15 minute intervals and a variety of I/O options, managing and analyzing your data is easy, even without a computer or PDA at the measurement location.
