The APERA WS200 is a portable, rugged handheld water analysis meter designed for accurate and reliable measurement of fluoride ion, pH, conductivity, salinity, TDS, resistivity, ORP (with separately sold ORP probe) and temperature. The patented 3-in-1 fluoride ion probe combines an ion-selective electrode, reference electrode, and temperature electrode for stable potential and rapid response time. Measurement range: 0.02 ppm to 1900 ppm fluoride; Accuracy: ± 0.02 ppm or ±5% of reading (whichever is greater). Features intelligent 2-point auto-calibration for fluoride (0.19 mg/L, 19.0 mg/L), 3-point auto-calibration for pH (4.00, 7.00, 10.01), and 1-point calibration for conductivity. With 800 data storage groups, the meter is ideal for both laboratory and field applications. The rugged silicone-gripped design with IP57 waterproof rating ensures durability in demanding environments. No sample preparation is required—fluoride ion concentration can be measured directly like a pH test, with probe activation taking just 10 minutes.

Frequently Asked Questions

Does the fluoride probe require sample preparation or reagent addition?

No. The APERA WS200 measures fluoride ion concentration directly from sample solutions, similar to pH testing. Simply immerse the probe in the sample—no preparation, mixing, or chemical reagents are needed.

How long does it take to activate the fluoride probe?

The fluoride probe requires approximately 10 minutes of activation before the first measurement.

What calibration is required for fluoride measurements?

The meter features intelligent 2-point auto-calibration for fluoride using standard solutions at 0.19 mg/L and 19.0 mg/L. These calibration solutions are included in the kit.

Can I use this meter for both laboratory and field applications?

Yes. The WS200 is designed for both laboratory and field use. Its IP57 waterproof rating, rugged silicone-gripped housing, and portable design make it suitable for demanding field conditions while meeting laboratory requirements.

What parameters can this meter measure?

The WS200 measures fluoride ion, pH, ORP (with separate probe), conductivity, TDS, salinity, resistivity, and temperature. The patented 3-in-1 probe combines fluoride ion, reference, and temperature electrodes in one unit.

What is included in the carrying case?

The kit includes: W2100 meter, F501 3-in-1 fluoride probe, 201T-S combination pH electrode (ATC), 2301T-S conductivity probe (ATC), fluoride calibration solutions (0.19 mg/L and 19.00 mg/L, 50 mL each), pH calibration solutions (pH 4.00, 7.00, 10.1, 50 mL each), conductivity calibration solution (1413 μS/cm, 50 mL), screwdriver, 3 spare AA batteries, user manual, and portable carrying case.

How many measurements can the meter store?

The WS200 can store up to 800 data groups, including measurement values, units, timestamps, and temperature data.

What is the measurement accuracy for fluoride?

Fluoride accuracy is ± 0.02 ppm or ±5% of the reading, whichever is greater, across the range of 0.02 ppm to 1900 ppm.
