• Measure pH, ORP, DO/BOD and conductivity on one to three channels to maximize flexibility and productivity
• Digital probes are recognized by meters—no need to calibrate when changing probes
• Menu-driven operation for simple setup and ease of use

YSI's MultiLab multiparameter meters measure DO, pH, ORP and conductivity with just one instrument. These meters use digital probes for extremely precise measurements. Probes are automatically recognized once you plug them in, including each probe's calibration history. There's no need to recalibrate when you change probes.

The AutoRead feature constantly evaluates your measurement's stability to ensure reproducible results. When measuring pH, a bar graph indicates if you are measuring in the optimal pH range for your calibration values. Save data sets manually or automatically based on user-defined time intervals. When saving automatically, progress is graphically shown on the display. Transfer data to your computer as a .csv file through USB connection for further analysis.

Single-channel MultiLab meters feature a large easy-to-read backlit graphic display. Store 500 data sets manually, or 5,000 data sets in automatic logging mode.

Two- and three-channel MultiLab meters feature a large color graphic display that shows readings for either all channels at once or one channel at a time. Keypad is antimicrobial. Store up to 500 data sets manually, or 10,000 in automatic mode.

Intelligent probes are galvanically isolated digital probes that store their own calibration history and serial number. Measurements are processed and transferred digitally, which compensates for variable cable lengths and eliminates signal interference. pH probes with built-in ATC are designed for fast, accurate measurements. The self-stirring ProOBOD optical BOD probe features a built-in sensor guard that protects the sensing tip from being scratched when placing into BOD bottles. Conductivity probes feature four graphite electrodes for very accurate readings (K=0.475 cm-1).

Meters include: universal power supply, electrode stand, manual, software and USB cable. Meter kits include: items listed above plus probes (see order table). 3-year meter warranty.
