Model UT Under Tank Reference Electrode by EDI

Description

Model UT reference electrodes are designed for taking potential profiles through perforated or slotted pipes beneath aboveground storage tanks. Contact to the electrolyte is through an all wood membrane which is more resistant to breakage and will not clog with salts or dry out as rapidly as a ceramic membrane.

Electrodes outfitted with two non-metallic ring bolts can be pulled through from either end of the pipe. When access is only available at one end of the pipe, use the S version which has a threaded socket at one end. This can be pushed or pulled from the open end.

Applications

Measuring potential profiles in perforated or slotted pipes beneath aboveground storage tanks

Features

• All wood membrane for contact to the electrolyte
• #14 RHW/USE lead wire is standard

Model UT1

Model UT1 was designed for use on tanks where the undertank piping terminates in a short radius ell. A user-attached sponge can be fitted to reduce contact resistance.

Weight - approx. 1 lbs (1/2 kg) plus wire #14 RHW wire: 1.5 lbs (0.7 kg) /100 ft (30 M)

Design life – 5 years (intermittent use).

 

Model UT2 and UT3

Models UT2 (for 2 in. dia. pipe) and UT3 (for 3 in. dia. pipe) can be left permanently in place in the slotted pipe and pulled through whenever potential profiles are required.

Weight - approx. 2 lbs (1 kg) plus wire #14 RHW wire: 1.5 lbs (0.7 kg) /100 ft (30 M)

Design life – 10 years (intermittent use).
