MW170 MAX | Bench Meter

MW170 MAX is a compact and versatile bench meter that can measure up to four different parameters: EC, TDS, salinity (in PSU, g/L, percentage NaCl) and temperature. The main operating modes are setup, calibration, measurement and logging.

• Fast easy to read results with large duel level digital LCD readout.
• Extreme accuracy to 1% of reading for EC/TDS/NaCl |+/- 0.5°C (+/-0.9°F).
• Extended auto-ranging feature for EC/TDS/NaCl.
• Lightweight, sleek design featuring a small benchtop footprint.
• Simple easy-to-use logging; manual log-on-demand or manual log-on-stability up to 1,000 records.
• Micro USB Port download functions.
• GLP data, date and time.
• Easy measurement: just place the probe in the sample, gently stir and wait for the reading to stabilize.
• Single cell factor calibration for EC/TDS/NaCl, automatic simple one point calibration and two point for temperature allowing increased accuracy.
• Rugged low maintenance, high performance, easy-to-clean EC/TDS/NaCL/Temp probe.
• Built in temperature sensor.
• Internal clock date to keep track of different time-dependent functions (calibration, timestamp, calibration time out).
• 3 feet probe cables for extra flexibility when testing.
• Includes MA9315 electrode holder, cables, adapter and probe.
