The WS100 Fluoride/pH Meter from Apera Instruments was specifically designed for the accurate and reliable measurement of fluoride, pH, ORP (electrode sold separately), and temperature. The patented F501-S 3-in-1 fluoride ion electrode consists of an ion electrode, a reference electrode, and a temperature electrode. It produces reliable readings with a stable measurement potential and fast response time. Stirring the sample solutions or adding reagents is not required during measurement. The fluoride ion concentration of the sample solutions can be measured directly, just like with a pH measurement (activation of the fluoride electrode takes only 10 minutes before measurement). For pH measurement, the set includes a 201T-S pH electrode, which allows automatic temperature compensation thanks to its integrated temperature sensor. The WS100 has a memory function and can store 300 data groups (numbering, measured value, measurement units, and temperature value).

• Fast and easy fluoride measurement using the patented F501-S 3-in-1 fluoride ion electrode – no stirring or addition of reagents required
• Very user-friendly thanks to a large backlit display, self-diagnosis function, automatic calibration and convenient measurement procedure
• Reliable pH measurement using the 201T-S pH electrode with automatic temperature compensation
• Memory function for 300 data groups (numbering, measured value, measuring units and temperature value)
• Ideal for laboratory and outdoor use: Waterproof and dustproof (IP57), robust and portable design with silicone case for a firm grip
