TELLI is a 'non-contact' liquid level measuring device, meaning there is no risk of cross-contamination or chemical exposure. It affixes to the outside of the chemical waste container. TELLI 'talks' to the user, alerting everyone that the container is nearly full. It is ideal for laboratory waste container spill prevention.

• Easy to set up and maintain
• Prevents overflows
• UL tested for non-sparking
• Great for use on HPLC waste containers
• Works on glass and plastic containers
• Fits containers as small as 2L and as large as 40 gal.
• Includes 8' USB cable (300 V) - USB power means there is no battery to fail and cause a spill

TELLI, the Talking electronic liquid level indicator, uses radio waves to tell when a vessel is nearing maximum capacity and alerts you to empty the container before dangerous spills occur. Powered by a USB cable, it can use any USB power brick or computer port.
