Portable Multiparameter PH meter/ Conductivity meter/DO meter
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.
PH Mode:
Auto recognition of 25 buffers with three kinds of options: Europe & USA, NIST and China. Support 1, 2, 3 point calibration.
Conductivity Mode:
Adopt advanced conductivity measurement technology, with conductivity electrode (K=1), it can meet measuring accuracy requirement for range of 0.5μS/cm ~ 200mS/cm.
Can switch among conductivity, TDS, salinity and resistivity. Multinomial calculation for TDS and salinity to ensure the conversion precision of the full scale.
Auto recognition of 8 conductivity standard solution with 2 kinds of options: Europe & USA, and China.
DO Mode:
It has functions of ATC, auto salinity compensation and manual pressure compensation.
Polarographic DO electrode, short polarization time (3-5 mintues).
