VIKING-M310 Portable Multi-Parameter Meter
Overview
The VIKING-M310 by COLO.Science is a portable meter for pH, mV, pX, ISE, conductivity, TDS, salinity, dissolved oxygen, and temperature. It is easy to read and simple to use.
Moreover, the 4.3″ touchscreen improves navigation. Therefore, set-up and routine work take less time. In addition, the IP65 housing supports field use.
Key Features
- Up to 1000 data sets per parameter with GLP.
- Auto-read, timed-read, and continuous-read modes.
- USB for data transfer and printing.
- ATC/MTC for stable and accurate results.
Measurement Modules
pH / mV / pX / ISE
pH supports 1–5 point calibration with buffer recognition. Moreover, electrode diagnostics show slope and offset. ISE offers direct, standard addition, sample addition and GRAN methods.
Conductivity / TDS / Salinity / Resistivity
Set the cell constant, temperature coefficient and TDS factor. As a result, results stay consistent across ranges. Temperature compensation supports none, linear or pure water.
Dissolved Oxygen
Calibrate in air-saturated or zero oxygen. In addition, barometric pressure is compensated automatically. Salinity correction is manual when needed.
Applications
Use the M310 in water quality labs and environmental monitoring. Therefore, it also suits industrial process checks and on-site control.
