WALK-IN DIGITAL SOLAR POWERED THERMOMETERS

Weiss Instruments, the industry leader in commercial thermometers presents

our complete line of Digital Temperature Indicators. Our patented "Solar Only"

light powered thermometers are the standards in the industry with the lowest light

levels and a variety of styles that compliment OEM Equipment.

All Weiss digital thermometers feature our exclusive "sealed sensor" technology. A unique

design incorporates a fully (food grade) potted sensor combined with our press-fit sensor bulb stopper, keeps moisture out and the temperature right. With over one million units in the field since 1992, the Weiss sensors are a proven design. Completely food grade construction, the sensor

can be custom designed for various lengths, bulb materials, sizes and insertion configurations.

Designed for commercial installations, built with NSF accuracy and compliance, see our complete listing at www.nsf.org . Weiss Instruments has digital thermometers for every application.

Weiss Instruments is the Patent Holder of #5196781, which features a no battery design and reliable readings in very low light applications. The LCD (Liquid Crystal Display) is bold and easy to read. The extra benefit of these units is that being "Self - Powered" they need no power line or batteries to operate and therefore no need for periodic maintenance.

Advantages of Light Powered Only vs Battery Back-up Design :

a. The battery will eventually fail, making the unit unreliable.

b. The battery will leak toxic material after some time.

c. Limited ambient temperature ratings - batteries don't work well in cold temperatures._

d. Service problems in the field.
