Portable Conductivity Meter (QXM-CD327 )

Portable Conductivity Meter (QXM-CD327 )

Measuring range includes Conductivity (0.00 μS/cm to 199.9 mS/cm), TDS (0–100 g/L), Salinity (0–100 ppt), and Resistivity (0–100 MΩ·cm), with a resolution of 0.01/0.1/1 μS/cm and 0.01/0.1 mS/cm. Accuracy is ±1.0% FS and overall ±1.5% FS. The device measures 165×90×32 mm, weighs 0.31 kg, and has an IP57 protection grade.
Features

• Large LCD screen with controllable white backlight
• Built-in microprocessor chip has intelligent functions such as auto calibration, ATC, data storage, function settings, auto diagnosis, auto power off, and undervoltage prompt, etc.
• Adopt advanced conductivity measurement technology; with conductivity electrode (K=1), it can meet measuring accuracy requirement for range of 0.5 μS/cm ~ 200 mS/cm
• Can switch among conductivity, TDS, salinity, and resistivity. Multinomial calculation for TDS and salinity to ensure conversion precision of the full scale
• Auto recognition of 8 conductivity standard solutions with 2 kinds of options: Europe & USA, and China
