Optiflow Digital Volumetric (Bubble) Flowmeter

• Bubble action works on very small leaks.
• Nontoxic, noncorrosive, nonflammable formula does not contain chlorine, aliphatic amines, or ammonium compounds.

Composition: Deionized water and a surfactant.

Temperature rating: Can be used over a temperature range of 27 to 200ºF (-2 to 93ºC).

Optiflow digital bubble flowmeters automate the bubble flowmeter "positive displacement" technique, which works independent of the type, mass, or mixture of the gas being measured. These high-precision instruments combine the simplicity and versatility of a bubble flowmeter with the speed and accuracy of a microprocessor. This provides you with a reliable means of measuring gas flow.

These versatile units can be used with all gases. Plus, they feature an easy-to-read, accurate digital display, eliminating the need for tedious bubble watching, timing, and flow rate/time conversions. The bubble is visible for your observation.

• Accurate to within ±3% of any reading
• Portable - includes standard 9-volt battery
• Automatic power-off for extended battery life
• Field replaceable tubes
