Product Description
Apera Instruments WS Series
Portable Fluoride and Multi-Parameter Meter Kits
The Apera Instruments WS Series (WS100 and WS200) delivers advanced, laboratory-grade electrochemical testing for Fluoride ions directly to the field. Designed for municipal water treatment plants, environmental monitoring agencies, and industrial compliance testing, these portable meters utilize high-performance Ion-Selective Electrode (ISE) technology. This method offers significant advantages over traditional colorimetric photometric methods by eliminating the need for complex, time-consuming reagent mixing and preventing interference from water color or turbidity.
The WS Series is built around a highly intelligent digital chip that simplifies ISE measurements. It features automatic 2-point calibration for fluoride, automatically calculating and displaying the slope to indicate sensor health. Beyond fluoride, these meters are true multiparameter powerhouses. The WS100 seamlessly handles both Fluoride and pH measurements, while the flagship WS200 expands capabilities to include Conductivity, TDS, Salinity, and Resistivity. This allows field engineers to comprehensively map a water matrix's profile using a single rugged instrument.
Encased in an IP57 waterproof and dustproof housing with a protective silicone sleeve, the WS Series is built to endure harsh field environments. Each model is delivered as a fully equipped turnkey kit inside a durable hard-shell carrying case, containing the meter, the Fluoride ISE, complementary pH and/or Conductivity electrodes, and a complete set of specialized calibration standards and buffers.
