WS100 Fluoride / pH Portable Meter Kit

Apera Instruments, AI4725, WS100 Fluoride/pH Portable Meter Kit with 3-in-1 Fluoride ProbeIncludes:Meter (1)3-in-1 Fluoride Probe (1)Combination pH Electrode (ATC)Fluoride Ion calibration solutions (0.19mg/L and 19.00mg/L, 50ml for each)pH calibration solutions (pH4.00, pH7.00, pH10.1, 50ml, one for each)Screw driver (1)Back up batteries (3)Instruction manualPortable case.The Fluoride/pH Portable Meter Kit is designed for accurate and reliable measurement of fluoride, pH, ORP (probe sold separately), and temperature altogether. The patented 3-in-1 Fluoride Ion probe is composed of an ion electrode, a reference electrode, and a temperature electrode, generating reliable readings with stable potential and fast response rate. Range: 0.02 ppm to 1900 ppm; Accuracy: +/-0.02 ppm, or +/-5% of reading (whichever is greater).Intelligent Functions:2-point automatic calibration (0.19mg/L, 19.0 mg/L) for fluoride3-point automatic calibraiton for pH (4.00, 7.00, 10.01 pH)300 groups of data storage (measurements, temperature, units of measurements)Auto. power-offBacklight adjustmentSelf-DiagnosisUnits switchable from mg/L, ppm, ppt, and pF.Convenient Use - There is no need for probe stirring or added reagents during tests. You can directly measure your sample solutions' fluoride ion concentration just like pH test (only takes 10 minutes to activate the fluoride probe before tests). Rugged design with IP57 water resistant rating, and a silicon case, which gives you a firm grip.Features:Patented 3-in-1 fluoride ion probe - no need for stirring or added reagents, directly measuring the ion concentration of fluoride in a quick and simple mannerStable potential, fast response rate, convenient use; 2-point auto. calibration for fluorideComes with an ATC pH electrode, testing fluoride, pH & temperature altogether with high accuracyLarge backlit screen, 300 groups of data storage, self-diagnosis, parameter setupRugged portable design, IP57 Water-Resistant Rating, ideal for both lab and field test.
